I JUST RECENTLY HAD HEAD/CAM INSTALLED ON MY 2000WS6.WELL THE CAR IS RUNNING LIKE CRAP.SO WAS DOING A HEADER INSTALL AND WHEN I PULLED THE MANIFOLDS OFF THE HEADS THE EXHAUST PORTS ON THE HEAD HAD A THIN LAYER OF OIL.ALSO THE PLUGS WERE COVERED WITH OIL AND FUEL(THICK BLACK SUBSTANCE)THE WEIRD THING IS THAT MY CAR IS NOT BURNING OIL AT ALL.WHAT THE HELL CAN BE CAUSING THIS?THE HEADS ARE TEA 1.5 5.3 HEADS

 

check your PCV system. ...sounds like the motor is sucking in oil on the intake side...

...a common problem that is cured by an Ls6 valley cover swap and use of an oil catch can...

 

WHAT PARTS ARE NEEDED TO DO THIS SWAP?

 

WHEN I HAD THE INTAKE OFF IT WAS FULL OF OIL!
