well I won't have my car a Pete's on saturday. My car is in apart because after I replaced the lifters there was still a slight ticking noise that was driving me nuts! I spoke with the ford tech line and the 32 valve engines are having problems with #1 and 3 cylinders valve guides. They said it starts as a ticking, then a rough idle and will throw a code. So I am in the middle of a head replacement. I had heard of all the probems with the drivers head but not the passenger. Have you guys heard about this before? I guess this head should be a updated part that mid 04 cobras are supposed to already have.
