I believe the early head gaskets 93-95/96??? will all leak.

It is a problem of a bad design.

It has been said by many of the techs and moderators on this forum that the head gaskets were redesigned several times, and that finally the newest gaskets do not leak due to metal inserts in the gasket.

I did a search and found this one. According to these mechanics, it is unheard of to go past 100,000 miles w/o a leak. My head gasket started leaking at 130,000 miles with a small drip, but by 137,000 miles, it was leaking tremendously bad and I have had the gasket changed:
