With out going into detail, because I don't have too many, a freind of mine ran a VW beetle with out a generator belt for a rather extended period of time, say 4 miles or so.
I looked at the engine tonight and first off the plug wire boots that seal against the cylinderhead tin are melted! I pulled the valve covers off and the rockers are dry with all valve lash being over tight. I couldn't fit any feeler gauge. So I replace the belt, plugwires, and set the valve lash at .006". The engine still feels like it has very low compression. I can not get it to fire at all. The only other thing I can think of would be changing the sparkplugs. Could the heat have killed the plugs too?
How bad could the damage be? Warped heads, burned valves.... rings.. ect? Can I get this engine running again?
I've never overheated one of my aircooled cars ( one 914 and three Beetles) so I don't know what to expect.
