The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

1992 Chevrolet G Series Van (G20) Reviews
I was driving my 1978 GMC 3/4 ton van from Connecticut to Maryland for the Thanksgiving weekend, 1985. 10PM at night,65MPH, extremely light traffic. In those days, the CT. turnpike had a toll plate about every 20 miles or so, 35 cents just to break up the monotony. There was a light rain falling so I was using "intermittents" to sweep the glass. Temp was right at freezing but I wasn't scared, I was in my van.
Coming to the New Britain toll plate I let off the gas and did a brake check. the road noise went silent and I started to slide, straight ahead, 65MPH.ICE, so I let off the brakes, the road noise from the tires was back! The wheels started turning, I steered a correction and touched the brakes again. Yeah, Start to slow down then the road goes silent again and I start to slide again. Dang, the toll booths are coming up fast and I'm still doin 50!
These gates at the toll plate are protected by 6 foot high concrete wedge, you know, shaped like the bow of a boat so if anything hits it the toll collector wont be hurt. I try the brakes again and get her slowed to about 35 MPH when I lose traction for the last time. I say the last time because I am gonna hit this abutment, or not. So I let off the brakes and aim for the slot. I can still see the lady's face as I crashed her gate doin about 30 MPH. The little wooden toll arm that hangs down until you pay was turned into a million little toothpicks. Poor thing rode up the glass about halfway and exploded. Holy cow! After i get through the gate I slam on the brakes and come to a complete stop.Go figure, They salt the exit side and not the approach. The wipers sweep the glass clean. Check that out, both wipers are still on the van and working! I jump out and run back to the gate, toss in my 35 cents which I was holding the whole time and said " its really icy up there!" to the lady who was unable to reply. I ran back to my van and continued all the way to Dunkirk before checking for damage. I will report I had too buff and wax, but not even a dent. In 1995 I finally laid this van too rest after 440,000miles, although I have transplanted her 400cid/400thd into a needy 1972 Monte Carlo. Greats times
