Hey everyone..didn't know where I should post this so I figured here would be fine. I was just wondering if the LIM problem that seems to consume so many Grand Ams, does it also affect the Malibu since the engines are identicle except for bore size? Thanxs.

I would immagine so - its a poorly designed manifold/block mating scheme that is not unique to the 3400 in Grand Ams

I had the same LIM problems in my 1996 Monte Carlo with the 3100 motor.

What happens, is the gasket gets "squished" and the pressure causes it to break. The new redesigned manifolds have a metal clip to prevent it from being squished.
