You need to do some exploring before you make a big decision on this one. If you have rings so bad they are causing that much blow by, I would think the truck would be smoking like hell. Perhaps you have a hole in a piston, or a blown head gasket.
Bad rings, or a hole in a piston are going to mean a rebuild or replace engine. Blown head gasket is not a hard or expensive repair. If you don't have a knowledgeable friend to help you, determine the problem, then take it to a reputable garage for an estimate.
Good luck Frank
