Has anyone else had a problem with the 3400 leaking antifreeze out of the right side of the engine? Mine just started. It looks like it is coming out where the coolant goes into the block. Just wondering if anyone has had this problem. I am just hoping that it isn't the head gasket.

LIM gasket needs to be replaced. (lower intake manifold) if kinda a "normal" problem with the 3400. normal that it most certainly will happen. get it fixed ASAP!!!! and dont use GM's replacement its still crap get an aftermarket one. i forget who makes it, but it made better than GM's. gl :thumb:

use the search option to find out more. theres been millions of posts here on that crappy gasket.
