That might make some sense based on the sound I'm hearing, although I have read that people claim they're bulletproof :\

Do you have any idea how difficult it is to replace those? I am at the mercy of my own wrenches and ability, as in this area, the dealer is the only other one that will work on it, and we all know how reasonable they are (not). No doubt they will tell me I need a new 1/2 or whole engine.

Thanks.
