Hello Bill,
I know you’re a whiz at this Lincoln stuff!!! A couple years ago, you solved an A/C Relay issue on my ’89 TC while I was down in Clearwater visiting!!
I have a 1969 Mark which has a couple mysterious leaks which I cannot find the root cause for.
One is an oil leak, which leaks only after I shut the engine off, and only a couple drops, but enough so that I can’t park the car in the driveway. It appears to be coming from between the Power Steering pump and front cover. I do have the seal installed correctly, put in place from the front of the cover, and the seal is brand new.
The other is an antifreeze leak which is allowing a small amount of coolant to pool in the valley (at the top) of the front cover, which leads me to believe its the front cover gasket.
All this being said, the engine was completely rebuilt last year and every gasket, seal, component is BRAND NEW.
Any insight would be greatly appreciated.
Thanks,
Dan K.

Greetings Dan –
Any of these kinds of leaks can sure be annoying and some can be tough to find. The oil leak can be easier to locate if you clean the area completely and then observe that location after shutting off a hot engine. There is a need to determine if the oil leak is engine oil or power steering fluid, of course it is best seen with the front end of the vehicle raised if possible. The front cover to power steering pump seal is best inserted into the cover clean, dry and coated with a good contact adhesive on the front cover side that dries quickly and completely. We highly recommend this procedure.
The coolant leak must be correctly diagnosed as well in order to not misdiagnose and end up dismantling assemblies that do not leak. Coolant leak areas should be closely observed with both a cold and a warm engine. Ideally the use of a cooling system pressure tester is best used to pinpoint the suspected areas. These testers provide the necessary pressure to diagnose without starting the engine. A good radiator shop should be able to do this procedure for you.
Always remember that ACCURATE diagnosis is half the battle. We hope that the above helps of course if we can help further with any parts or advice etc. please contact us further.
Sincerely,
Bill
