| Re: Root Cause of Head gasket Failure and a Fix?
Interesting, having not seen a N* apart (only became an owner 2 mos ago) I did not realize GM designed it with an open deck. I've never been a fan of open deck motors, because typically gasket sealing is an issue (especially at *ahem* elevated power levels) along with core shift and distortion of the cylinders, N* block casting issues aside. GM seemed to learn the lesson, since according to your pics the newer RWD N* were redesigned with a closed deck, and they did the same with the LSx series V8s when they were released in '97. |
