Yet another Seafoam question

[camaro_speedemon]

Not how to do it, but should I do it. I have a slight exhaust leak in my cooling system. It's not really bad, my fried has a CO2 test kit he used and it turned the chemical a slight shade of green, indicating a small amount of exhaust gases in my cooling system. I want to clean out my engine, but I think that maybe some of the "gunk" in the engine might be keeping the leak small and if I clean it out, the leak may get worse. What do you guys think?

I'd use it, clean out the gunk, and if your leaking more, fix it [img]graemlins/thumbsup.gif[/img]

I need to wait until I have my other motor onhand before I could fix it. I don't know if it's a headgasket, or a crach in the block. If the block is cracked, then I can't fix it :(
