How do you fix or replace a blown out head gasket for a 1987 Astro Van?

This is a major repair and requires a skilled mechanic. You have to take the head off. and replace the gasket and get it put back on properly. Unfortunately, something made the gasket blow and once you get the engine apart you will likely see that the rings and pistons are worn and the valves need regrinding , etc, etc. I do not know about the Astro Van, but you may have to take the engine. If so, this is a major job , requiring some kind of hoist, in itself, as is putting it back in. You might do better by selling the car for parts.
