Reliability of 996 Engines

If you actually have a bad head gasket (which I cannot see in the photos), you would be the very first head gasket I have ever seen fail on one of these engines.

 

By far, the two biggest reasons for intermix on an M96/97 are cracked cylinder heads, or cracked cylinder liners:

My engine also blew up.  The more I learn about these engines, the more I realize how much of a crap shoot it is.  Some folks are lucky and some folks are not so lucky.  Going to do a LS swap.  Will probably outlast every single m96 engine on the planet.  I do not see these cars around in 30 years..

Welcome to RennTech:welcomeani:

Before going down the LS path, you might want to talk to one or two of the forum members that have done the LS swap; general consensus is that they would never do it again.
