Default LIM Question?

Im curious, is the LIM UIM problem common on the L67 engine? I know it is for the L36 but is it on the L67?

There is a LIM gasket problem that I'm aware of. The L67'* UIM is the supercharger so it can't melt like the plastic UIM on an L36.

If your PA Ultra is truly at 115k like your signature suggests, you're long overdue. I'd suggest doing it ASAP before you lose your motor. Yes, it'* intended to scare you, and no, it'* not an exaggeration.

Lose the DEX and go with either Fel-Pro gaskets or the new GM aluminum, OR keep the nasty foul and evil DEX and go with ALUMINUM LIM gaskets ONLY.
