Just some observations here guys...
I want your opinions, its sort of an open ended conversation thread. Maybe to vent more than anything.
Here is a picture of my GTP's LIM gaskets when they came out. I guess both banks gaskets were blown (big suprize there)
As you can see I have circuled where the gaskets have failed.
My question....
Why in the HECK would GM design little slits like this (pointed at with arrows) in the coolant passages of the gasket? It makes no sense to me at all.
It appears the gaskets always blow right where these slits are (same deal with the 3100's LIM problems, and I'm sure a lot more GM motors).
Only reason I can think of to have these slits is in fact so that the gasket
does blow, and the owner possibly returns to the dealership for service.
Something interesting to note is that the intake runners do not have these slits. Why is that? (seems suspicious).
Also GM redesigned metal framed gaskets and Fel-Pro brand gaskets do not have such slits. Why would that be?......(Interesting)
