Engine Mechanical problem
2001 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 160000 miles
My engine is the non-supercharged 3.8L. I just replaced my upper intake manifold due to warping that caused a coolant leak. This included removing the fuel rail and cleaning most of the top side of the engine. After putting everything back together I discover that it seems like my engine is starving for air in the vacuum lines. When I remove my oil cap there is a ton of suction through the valve cover. From my experience this has something to do with the EGR valve being plugged or not working. Could you give me heads up on how this might have happened while I was replacing my upperintake? Is it possible that I could have spilled coolant into the EGR valve tube?
