Heres the deal. My friend has a 91 5.0 that is supercharged. He brought it to me last week because of a blown headgasket. I swaped out the gaskets for him which fixed the burning coolant problem. But now it is burning oil. I pulled the upper intake and the gasket has oil all over it. What would cause this?

I can see the tabs on the head gaskets so I know they are in correct. There is a few vacume lines that are broken and not hooked up but he bought it like that. Could the PCV system cause oil to get in the intake like that? Need some suggestions any help would be great. Thanks

 

A faulty PCV could absolutely cause this, or even excessive crankcase pressure of blowby. That's why when I supercharged my engine, I had to actually remove the tube running from the PCV to the upper intake. Instead of having it connected to the upper intake, I installed an oil seperator / catch can and then vented it to the atmosphere.

 

Thanks man I'm going to try that. Anybody else?
