thanks for the replies,
Mike, the valves for this cylinder are covered in melted metal and i always used 91- 93 octane gasoline.
Freestyler, Thats exactly what I wanted to hear, thanks.
PaulG, I will look into the price of a piston, but with a hole in the old one and metal melted, isnt there going to be peices of metal all throughout the block now, and possibly the cooling system? A used one would not have this, although I guess I couldnt really know how good a used one is either.
Also How do I know the used one I could get isnt ready to die? Compression check, but what else. If I did get an engine is it worth pulling the head off and putting on a new head gasket while it is out of the vehicle?
