Check out a product called Blue Devil. That is all i can tell you about it. I just looked and youtube has a couple videos on this Blue Devil, one says it's junk, the other says best stuff ever! You decide. Of course you know what a mechanic is going to tell you to do, as we have never seen "miracle in a can"! I can't say one way or the other. However i do understand your predicament! - pushrod
