Head Gasket Leak or LIM Gasket?

Bozly · 01-17-2009, 03:34 PM

We have removed everything down to the exposed heads. After removal and inspection of the plugs, I dont think its the head gasket but the LIM gaskets. Is this a common problem? Thanks, Mark

On the 60º V-6 engines, the aluminum surfaces can deteriorate and allow leakage. They are repairable.

Could this be repaired without removing the head?

If the eroded/pitted area is thoroughly cleaned, it can be filled with a metal-bearing epoxy. Once the epoxy is cured it can be scraped flat treated like metal.

This one has lasted since February of 2006:

It is a common problem and get the Dorman kit which is complete with new bolts.The intake gaskets from the kit are made out of metal instead of the crappy plastic GM uses
