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 (G30) Reviews
I own a G30 Extended Van with HD emissions. It runs great and have had little problems with it. The biggest problem is Rust. Though the main body from about 1 foot up is in great shape the bottom rockers and panels are rusted out. I am in the process of replacement. The 350 HD engine is simple to work on and has plenty of power for a big horse like the one ton extended. A 7.4 would be even better. I have only done "maintenance work to it like oil, lube, O2 sensor...to it. The interior has held up great, though the carpet is in need of being replaced due to heavy hauling and grease. Over all, a good truck!
