Well, change of plans. Apparently, the exhaust leak sound I've got is in fact rod knock. I didn't crack an exhaust manifold on the trip up the Coq. last month, but actually spun a bearing. Took the truck into my exhaust shop for some help tracing the "exhaust leak" and got the bad news. So now I don't know what we're going to do. Tina and I are going to talk it over tonight but its not looking good for old "Solid Gold".
I think I need a beer...
