I'm no domestic guru by any means, I mostly work on my drift car but my Jimmy is broken with the classic water in my oil. I started pulling it apart the other day to diagnose whether its head or intake gaskets that failed.

After pulling off the pulley bracket on the drivers side bank (cyl.1,3,6) i noticed some chocolate milky sweetness leaking out between the lower manifold and the head. I compression tested all cylinders and they ranged between 120psi-130psi.

Should i be good and just do the intake manifold gasket? Or could it possibly still be head or both?

Any insight is much appreciated. Thanks

 

Definitely sounds like a failed LIM gasket.

Get the redesigned ones from Felpro that have an aluminum frame.

 

Yea that's what i figured, but i just wanted to make sure. I'm not too sure about the compression being ok considering i don't even know the compression ratio. I'll order a Felpro and call it a day
