My buddy has an 84 GMC Sierra with a chevy 350, holly double pump. He just bought it from a guy who just loaded him with problems currently their is a drain on the battery. The alternater is good, but we have to charge it before it will start. After it has been run for a little bit it begins to put out white smoke(can't tell where it is coming from) and dies. Also it splatters liquid aganst the radiator fan(can't tell were the liquid is coming from) that apears to be anti-freeze. Whatever the problem is it is getting progressively worse, because now it dies at idle and the only way to keep it up is to rev it. Also a shop claimed to of looked at it and said it needed a new starter. the starter is fine. It has dual straight pipes and a very small amount of white smoke comes out of one side. Some times a load pop is present when we try to start it. My dad suggested the head gasket, any imput would be appreciated!
