Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

1994 Chevrolet G Series Van (G30) Reviews
This van is a workhorse. I bought it used with 115000 miles on it blowing a little smoke. We put a lightly used engine in it and I have nearly 180000 miles on the body, with around 70000 on the motor. It has never given me a question in five years. The body is a little rusted (lower panels), the wheels have needed ball joints, tie-rods, and other stuff. Front end is loose. Minor electrical problems. But, it is a great truck that does all the work I put it through. People ask why I don't get a new truck....because this one pays me! I will do some light work on it and keep it...It's now nostalgic!
mine has 170,000 miles on it and we are having trouble with the engine.
