Ok, I am new to the 3.4
I am VERY familiar with the 3.8 from GM though. In the 3.8 community there is a huge debate on the whole DEX Cool and gasket issue. It is VERY rare to have a head gasket failure, but it is quite common to have a bad upper intake manifold as the ones in the 3.8 NA are plastic :yucky:and a failed LIM gasket.
Normally this is resolved by a new upper and a metal gasket.
I have heard nightmares about the 3.4 and the head gasket though and heard of issues with the coolant. I was actually advised to drain it an replace it.
So, what's the consensus here on this issue?
