So, this past weekend I dropped the 6 to look for a compression leak on the number three cylinder. As soon as the cooling shroud came off it didn't take long to find it.
It doesn't look too bad and now I will finally know for sure what pistons and cams I have. Also have to take care of an oil leak on the front somewhere. (or rear depending on what car or book (IMG:style_emoticons/default/smile.gif) ) Check it out. Attached thumbnail(s)

QUOTE(cnavarro @ Dec 9 2004, 10:26 AM) If it is a 2.0, that "head gasket" really doesn't help seal against that level of leakage, it's just more to reduce the combusion by-products getting blown into the stale air heat, or at least that's what I was told by an engine builder who does lots of 2.0 race engines. Charles Navarro LN Engineering http://www.LNengineering.com Aircooled Precision Performance Yes, the head gasket of a SB chebbie won't seal that level of leakage, either. It's just more there to keep the combustion products out of the water jackets. I read this somewhere, but may have lost something in the translation. |
