RE: 4.3L cooling system
I think you may be right about the head gasket. So on a whim I went to Autozone and bought a bottle of this stuff called "Blue Devil" it was $60 it says that no mater what type of coolant leak you have it will fix it guaranteed or your money back. A last resort before tearing the hole motor down. I will right back to let you guys know if it works.

Whats your oil pressure at?? Is it higher then normal?? If your losing coolant that badly I would check the oil dipstick tube to see if its a milky brown!! If so it could be your intake manifold gaskets that went out its one of the more common problems with our engines!!

The oil pressure is about 40 psi at idle. I put that "Blue Devil" in about a week ago and have not lost a drop of coolant since then. I will keep my fingers crossed. So far it is a damn good product.
