Up to this knock, it has been good
1995 Mercury Villager crankshaft questions.
I just had an interesting thing happen with my 95 Mercury Villager. I changed the spark plugs, and when I restarted the engine, a terrible knock appeared in the engine. I suspected bad plugs or possibly something dirty fell into the engine, but I feel that these can be ruled out, since the compression is good on all the cylinders. The engine has 200,000 kms. (120,000 miles) on it.
I have received two different opinions on this. First opinion from the dealer is that a piece of carbon dropped in and has been caught in the valves or something. They put in some engine cleaner and the problem seems to be better. There is still a knocking noise when the engine starts in the cold, but quiets down when the engine is warm.
A second opinion given to me is that likely the crankshaft is broken. It was just a coincidence that it happened after the plugs were changed. Does anyone know the symptoms of a bad crankshaft?
Would you buy another car from this manufacturer? Don't Know
