Re: Timing chain broke on 3.9L...
Hello I am new to the forum but have a very similar problem to this thread so I thought I would continue it. First off "schpenxel" what did you ultimately do.
I have a 2001 Lincoln LS with a 3.9 V8. Trying to start it the engine spins over like a bad timing chain. The car has run flawless till this time about 68,000 miles on it. Surprised at this mileage this would happen. Is this somewhat common on this engine. Can this happen without causing piston valve damage. Cranked the engine watched the pulley turned very rapidly without any resistance from compression. Engine cranks as though the plugs are out.
I have begun to disassemble the pass side valve cover is off 3 of 4 plug wells large amount of oil. The chain is intact but there seems to be significant play in the primary chain. The top guide is not in contact with chain? I hope to remove the driver side tomorrow and than start on the front.
Is it possible that coils being shorted by the oil could have caused this problem of cranking rapidly without starting? Once all the plugs are out I will do a compression check.
Any suggestion are appreciated
Thanks - Lanse
