"Do it Yourself" Repairing and Maintaining Your Lincoln Tips

Performing some of your own repairs and maintenance on your Lincoln can be rewarding in so many ways. Besides saving labor expense a successful repair gives you a nice sense of accomplishment. Over a period of time and several repairs, you as the owner can really get to know your car and how to go about diagnosing and approaching many of the issues that will confront you as a Lincoln owner.

Before "tearing" into a problem you should do a little research into the issue as it pertains to your vehicle. This can be done with the use of the correct Maintenance Manual and the correct Wiring Diagram for the car. Prior to embarking on a repair or adjustment etc., knowing the answer to such questions as when did the malfunction begin to occur, did it start immediately after another repair was performed or was the car purchased with the problem already happening? Being aware of the answers to these and other questions can really help in the correct diagnosis.

Knowing how to properly read your wiring diagrams is an art form in some cases as many factory publications are very congested and can be difficult to follow. Paying attention to the wire color codes etc. and having patience along with proper diagnostic habits and simple testing equipment can really pay off in the long run and save hours of frustration and unnecessary expense. As an example, consider that a fuse that is continuing to blow occasionally could be protecting other unknown circuits as well as the one that you are trying to repair. Learning this from the wiring diagram before starting a repair may suggest other logical avenues of approach in order to locate the culprit. On the other hand proceeding without this information can many times lead you to wasted hours and/or excess cost.

The above are just a few tips to help owners pinpoint some of the troubling issues that we all must deal with sooner or later. If any of these tips seem to help some of our customers, we will continue to include them occasionally in the Lincoln Land blog.

Sincerely,

Bill

1982 Mark VI Performance Issues

Bill -

I don't drive my 1982 Mark VI anymore, and days between short drives of just a few miles in town. Started noticing the idle increasing 8 months ago slowly over time, and the speed it wanted to go increased as the engine warmed up and then suddenly work fine after off for 30 minutes sometimes. Then a week ago I started it up and it started bucking and didn't want to run in gear, but as the engine warmed up it got a little better, but when I stopped for a few minutes at a store it didn't want to restart, even with it spinning fast, so I floored it and it sputtered to life, and I got home. Days later it started fine but acted the same way, but then at the same shop on restart no sign of trying to start, even floored. Towed it home and the next day today it started fine again but acting the same way. I am suspecting the EGR was sticking some, and now a lot. What would be your guess?

Greetings Dwight -

Could you forward your customer number so that we may look up your account with us? Also it would be helpful to know the tune up history of your Lincoln and what you have done so far to diagnose or correct your engine issue. The engine management system for your 1982 Mark VI engine was sophisticated for these early years of automotive electronics and therefore requires a shop manual to assist in pinpointing the culprit in a logical sequence. If a component such as the EGR is suspect for any reason, it should be tested as per the manual before replacing. "Guessing" is not a wise option. Do you have a shop manual or do you have a mechanic that has a factory shop manual along with some technical experience with these vehicles?

There is not an over abundance of Lincoln collectors who collect these early 80's years of Marks and many parts are becoming difficult to locate as time goes by. In your case there are some on going on line forums available for specific eras of vehicle whose members may have had experience with your exact issue and similar engine management problems.

1989 Town Car Shifting Question

Bill -

I just purchased this vehicle and had the engine professionally replaced since the previous owner overheated it and blew the heads. The transmission was also serviced. I was driving it and noticed that shifting from first to second was fine but from second to third there is a delay where the RPM's go up before shifting smoothly into third. Is this a normal function of that transmission type?

Robert

----------------------------------------------------------------------------------------------------------------

Greetings Robert -

What you are describing is certainly not normal behavior for that automatic transmission. The best advice is to take the car to a trusted transmission shop and have it road tested and evaluated for a possible internal transmission problem. A good transmission mechanic familiar with that era of Lincoln will also be able to ascertain if the transmission linkage and controls etc. were assembled and adjusted correctly during the recent engine replacement and transmission service.

Sincerely,

Bill

1967 Continental Starting Issues

Hi Bill -

I am working on my 67 Lincoln 4 door Sedan with the 462 engine and am having starting problems. I should say that the car is mechanically fully rebuilt and ran great, but was sitting for a while and now it seems that the gas in the carb drains back into the gas tank or disappears somehow, because the car wont start for a while till the carbs fill up and then it runs fine with no dying or hesitation - that's what it feels like. Any advice would be greatly appreciated.

Thanks,

Fred

----------------------------------------------------------------------------------------------------------------

Greetings Fred -

The modern ethanol fuels tend to evaporate quicker than the fuels of the sixties. The fuel cannot drain back into the fuel tank. I would first do a complete fuel system test. This will include a fuel pump pressure and volume test as per the shop manual and an inspection of the fuel lines hoses and possibly the fuel pickup in the fuel tank. The fuel pump must supply the correct volume and pressure in order to fill the carburetor quickly on an engine that has been sitting for a period of time. The pumps can be weak and/or the push rod that operates it could be worn to less than the necessary 4 and 13/16 " to operate it properly.

Sincerely,

Bill

1994 Continental Wiper Issues

Bill -

When the wipers are on Full does it still run through the intermittent Governor. My wipers stop after 10 minutes of driving, kick back in 10-15 minutes later. Today they did not kick back on. I opened the hood and when I closed it must jarred something because they started to work. What should I check as it is intermittent.

Randy

----------------------------------------------------------------------------------------------------------------

We usually diagnose these issues as per the shop manual. In your case and as a start, an examination of the hidden wiper linkage first for debris that has accumulated could be a good idea. Next would be to check for loose electrical connections at the motor etc. Be advised however that we do not have too many parts available for this year and model of Continental.

1979 Mark V Blower Motor Removal

Bill -

I can't find a procedure in my Factory Shop Manual for removal of the Blower Motor for my 1979 Mark V.

Thank you -

Ken

****************************************************************************************************************

Hi Ken -

That procedure seems to have been omitted from the 1979 shop manual. We are sending you the procedure from the 1972 manual for a Thunderbird. this should be the correct procedure for your 1979 Mark. Please let us know if this works for you. We stock many parts for your vehicle and we look forward to your first purchase from us.
Sincerely,

1969 Mark III Headlight Indicator

Hey Bill,

My headlight indicator light at the top started acting weird. Normally, I'm pretty sure it only lights up for a second or two right after you turn on the lights. But now, it stays lit up when I have my headlights on. If I had the lights on and quickly switched it off-then-on, it lights up instantly and stays on. If I turn it off, wait a few seconds, then turn them back on, it lights up after a few seconds and stays on. I'm worried, because I don't want the light to over heat the panel or plastic. Any help will be appreciated, thanks.

John

----------------------------------------------------------------------------------------------------------------

Greetings John -

You don't mention if you have the Automatic Headlamp Dimmer option. If you have this option and it is turned ON, the system may be trying to warm up and operate. The owners manual will explain this operation to you if you have one. Or are you referring to one of the over head panel light indicators above the windshield. This light advises you if the headlamp covers are open or not with the headlamps turned on. The manual should explain this operation as well.

Sincerely,

Bill

1973 Continental Starter Removal Issues

Hi Bill,

I am replacing the starter on my 73 Continental. I can get the existing starter disconnected but when it comes to actually removing from the car the steering linkage is in the way. I saw in an earlier response you suggested disconnecting the idler from the frame. I also read in an old Mitchell manual I have that I may need to turn the wheels to the right and disconnect the idler. The only problem is I still don't think I have enough room to wiggle it out and away from the car. I also thought about trying to take off the solenoid to gain more wiggle room but I don't know if that's a good idea. Any suggestions? Please feel free to email me directly, thanks!

Tom

----------------------------------------------------------------------------------------------------------------

Hello Tom -

The removal of the starter is shown on page 28-03-04 of the 1973 Factory Shop Manual for that style of starter on the 460 cid engine. It describes turning the steering linkage for a right turn and disconnecting the idler arm from the vehicle frame in order to maneuver the starter out on the Mark IV. There may also be a brace in the way and blocking removal that will need to be disconnected at one end as well. The full size Lincoln model may not require this procedure at all. If you have some aftermarket type of exhaust pipe or any other non factory parts etc. interfering, you will need to disconnect these parts. Another thought to possibly consider is that a badly deteriorated motor mount could be lowering the engine and causing some interference. Removing the solenoid from the starter prior to removing the assembly is not advised.

Sincerely,

Bill

1977 Town Car Headlight Door Issues

Bill,

Saw your response to another post about similar problem they had with a Mark V. The 77 Town Car I have is in Hawaii and no local mechanic seems to be able or want to find that vacuum leak. What's happened so far is when I got the car a few years ago, the leak was such that doors stayed shut for about 3 days before starting to gradually open. Both would open at the same time and at the same rate. The problem got gradually worse. Upon investigating this, somebody suggested trying to change check valve near fire wall. Did this. No change. Also changed headlight switch as that too was suggested as possible culprit. So car had to go into shop for over a year to get engine changed. When I got car back, doors were worse. Driver side door slow to open and close even when engine on. Passenger side opens and closes quickly like before. But now will fully open if car left parked for even a few minutes. I got a shop to look at it and even got them the large ford pamphlet/ book on the vacuum / electrical system. Unfortunately they are not patient to try to really get to the root of the problem. They just want me to obtain two new door actuators which are hard to find. Oh in addition I disconnected air line to driver side actuator to check hose connection and a significant amount of water came out. So probably the driver side actuator is bad, but not positive on passenger side one. Do you agree actuators are likely cause or how water could get inside driver's side actuator? Can you suggest parts to tell them to check and if you have these parts you could sell or direct me to where I could find them?

Thanks,

Robert

----------------------------------------------------------------------------------------------------------------

Hello Robert -

Several blog replies have been posted here regarding vacuum leaks and they all have similar information. Vacuum leaks can be located anywhere that the vacuum is routed and the total amount of loss will be the sum of all of the leaks that are found. We only recommend performing proper diagnosis to repair these systems. Without diagnosing you can consider every component that is shown in your shop manual a suspect. The vacuum motors (actuators) can very easily be tested for leaks and determined absolutely without doubt if they are leaking or not but unfortunately you have described the technicians that work on your car as impatient which is incompetence in my opinion. To sum up, I can sit here and type out ALL of the other parts that you have not "tried out" as culprits but that would be only guessing and a disservice to you.

We usually do stock most of the parts needed to repair these vacuum systems. Some components can also be successfully repaired in our shop.

The one possible way that water can be inside the lines etc. is that a sizable vacuum leak or leaks has the outside air entering the components and is condensing on the walls of the interior where the vacuum is routed. This of course is only a theory.

Although the headlamp door actuators are very popular leak areas I do hope that someone will diagnose and qualify them as faulty before you order replacement parts. As our customer we can offer to properly test any parts for you that are sent to us if you are unable to receive that service where you are located. Please check with George before sending us any parts for inspection.

Sincerely,

Bill

1963 Continental Acceleration Problems

Hi Bill,

I have a 1963 Lincoln Continental and having some acceleration problems. All started when my mechanical fuel pump died and installed an electric Carter pump, still no good. Then my mechanic thought my original carb was the problem (old and tired), so I installed an Edelbrock 750 with electric choke. Still ran the same, very sluggish and a hesitation during acceleration and an occasional backfire under load. Then thought it might ignition, so removed the points to a Crane points conversion kit. Then finally installed a MSD pro billet with vacuum advance. In the meantime I upgraded the battery cables, spark plug leads, coil and starter motor cable. The car is still doing it.

What can I look at next as I am running out of patience. Your help will be grateful.

Regards,

Angelo

----------------------------------------------------------------------------------------------------------------

Hi Angelo -

I am not sure of the performance and/or quality of the aftermarket parts that you have installed but if you and your mechanic are confident that the fuel and ignition are more than sufficient, please have your mechanic carefully read the enclosed blog question and reply from the Lincoln Land Blog of January 2013. Does this information sound like your issue? Let us know the results.
Sincerely,

Bill

1965 Continental Is Sluggish

Hi Bill,

I have been working on a customers 65 Continental for a couple of months now. He brought it to me saying it shut off on him one day and when he started it back up it was running rough and had little power. I have have been through this thing in and out, top and bottom. Did all the usual diagnosis stuff and have changed parts as I have found defects. The car was running rough at idle and would break up real bad when trying to accelerate, popping back back through the carburetor and smelling very rich. The first thing I did was rebuild the distributor, it wasn't advancing and the plate was very corroded. That didn't help at all. I pulled the timing cover to check the chain and marks and that was fine so I pulled the intake and discovered the lifters were seizing in the bores. I cleaned the bores, installed a new camshaft, lifters and timing chain set. While I had it that far down I sent the heads to the machine shop and 500 bucks later they were fixed with a few valves and all new springs. All the rockers are free and pushrods not bent. After all that the car idles as smooth as a brand new car, but still have no power and can barely accelerate. New coil, 12 volts to the coil, new cap and rotor, timing set at 10 degrees ( have tried it from 6 to 16 degrees), 5-6psi fuel pressure at the carb, new helper fuel pump near the tank, compression is 130-140 on every cylinder after warm-up. After all this the car still has very little power, breaks up during acceleration and is still slightly popping through the carburetor at WOT. You can see a mist of fuel with a flashlight coming out of the top of the carb while power breaking it at half throttle. I've hit a brick wall with this one, its the first 430 Ive ever worked on, I'm too far in it to stop now. Any ideas or advice? Thanks so much.

Andy

----------------------------------------------------------------------------------------------------------------

Greetings Andy -

After reviewing your letter several times and reading what you have done so far with this engine and assuming that all of your work has been done correctly as per the engine's specifications etc. I can offer the following. The factory exhaust systems on these engines use a " double wall" exhaust pipe. These of course are the pipes that bolt up to the exhaust manifolds and continue on to the next flange connection rearward. It is not unheard of for the inner pipe to develop a separation in such a way as to severely seal up the exhaust on one side enough to cause the symptoms that you are describing. When this occurs the outer wall remains intact and no exhaust leak is heard. Because of the exhaust heat factor this final "plug up" can take place in a very short period of time as your customer has described to you. If the vehicle has the original style pipes on it you should remove them for a careful internal inspection.

Two other items to be aware of when tuning or servicing this era of engine are...The damper pulley on the crankshaft can separate from the rubber damper material and give you an incorrect timing reading. These are available rebuilt. The second is that the vacuum advance units on the distributor are well known to seize or rupture and become inoperative. These are available new.

I hope that the above helps you and I would ask you to let us know here at Lincoln Land what you find.

Sincerely,

Bill

1965 Continental Is Sluggish - Update

Bill I can't thank you enough for the advice, I unbolted the exhaust just before the muffler's and sure enough the passenger side exhaust pipe was clogged shut. I ran 2 new pipes from the manifolds to the mufflers and the car runs perfect!! I've run into double walled exhaust pipe problems before but 99% of those cases were on Honda's. I had no idea these Lincolns were manufactured with it and probably never would have checked it.

Thanks again,

Andy.


----------------------------------------------------------------------------------------------------------------

Hi Bill,

Thank you for your advice, being way over here in Australia it is a bit hard to find anyone with any experience at all with these cars. They have their querks and I guess that's part of the reason we love them! I think your blog from Jan 2013 is quite interesting in relation to my car. I had the exhaust built new but(there's always a but) the exhaust guy couldn't undo the bolts on the end of the headers and was worried about snapping them of if he applied too much force, so he left about 3 foot of original pipe and then welded a flange and continued with new pipe. So my problem could may aswell lie there.

Can I also ask, he recommended only using two mufflers before the diff so that they would run hotter and wont collect any water in them due to the fact that as we don't use these cars all too often enough, and thus avoid any rusting away in the muffler.

I forgot to mention last time that the car ran beautiful at idle and cruising at slow speeds runs great, and on the open freeway at about 60 mile/hr runs even better(there's not enough road ha ha) its just that acceleration problem I cant handle. I tell you that I wont rest til I fix that gremlin in there. Cheers again Bill.

Regards,

Angelo

----------------------------------------------------------------------------------------------------------------

Angelo -

Everyone has their own opinion and there is plenty to read on the internet regarding exhaust systems. I personally only go with all of the original components on my systems because I enjoy the "Lincoln Quietness" of the factory installations. The available quality (and of course more costly) stainless steel components that are available do not rust out. Be advised however that the cheaper stainless exhaust parts are usually NOT of the optimum quality in all respects. In the end it is up to you according to your wants, needs and affordability. We wish you luck in diagnosing your recent engine issues.

Sincerely,

Bill
