Just got this Lincoln running for the first time since I’ve owned it, as it sat for 10-15 years prior to that. Ran great, idled just fine, started it up a few times. The last attempt, I revved it up pretty good and then it just died. Not sure what happened when I revved it up, but now it turns over like there is no compression. Still getting spark, still getting fuel, rotor is turning but appears to be not pointing at #1. My guess is that the timing chain slipped or the camshaft sprocket teeth broke off. It is still original. Does that sound like the right path to go down?
Hi Michael –
If that problem as you have explained happened to myself, I would begin by taking a compression test of the engine and then removing the valve covers to check for bent push rods. Bent push rods will indicate seized valves. Not knowing the actual condition of that engine, seized valves and needing a valve job may prove to be only the beginning. If you suspect an issue with a loose timing chain as well, that will certainly need close inspection also.
Sometimes engines that have been dormant for years and years such as yours start fine and seem to run o/k at first and then fail suddenly after a short time. The years of sitting unused catches up to them and they seize. An overhaul may be imminent in your case but correct diagnosis could prove otherwise. You should have the correct factory shop manual at your side for this challenge and I would also be looking for a “good” local engine/machine shop. Lets hope that after the correct diagnosis the problem turns out to be a small one for you.
