They lose cylinders horribly die to longitundinal bore scuffing. Big reason for it, called improper skirt clearance with a forged piston.

When I see people" upgrading" to an OEM 3.8 I just shake my head.

Upgrade? The 02-05 engines have the worst issues of all.

I was just reading on another forum where the 997 guys were referring to 2000 rpm as the "bore-scoring" zone. any truth to this? apply to us m96 guys too?

How sloppy are these things that you get piston slap (scoring) at 2k. Is this a case where you hear about the 1% of disasters LOUD and all the other happy drivers are mum?

An M97 is just an M96 with a different name.
