A few days late on this post, but I just called a local shop (I'm in Raleigh NC) and was told the head gaskets dont go on the 96-99 2.5's. He said the cylinder walls crack.
First I've heard of this. I always had heard my bubbling radiatior, overheating symptoms were caused by the gaskets.
Anyway, I too am now looking at options. ~ $2000 for head gasket replacement or about the same for a rebuilt engine from SSI?
