I am one unlucky son of a gun. I just lost second engine in my Buick. The first one was my fault, the most recent one was just fate. But I have a quick couple of questions. The first is in regards to the lower intake gasket failing. I have coolant all in my oil, and the location of the breakage on the LIM gasket is around the ports on the LIM that are blocked off.
Second question, can failed piston rings really cause oil to make its way all the way up into the UIM? The lower ports were completely coated in an oil and carbon film while the upper just had a spots here and there on the runners. Was it a head gasket and piston rings or LIM gasket and piston rings?
I forgot to say, There's an exhaust flange leak that is causing the engine to run rich as can be. That's likely where the carbon in the LIM came from.
