Im not sure if the head gasket is blown but i beleive it is. It overheats at freeway speeds and I can drive it in city traffic for about 25 min before over heating. Then coolant bubbles out of the radiator. And today i saw a small pubble of oil on the top of the engine towards the back of the engine. No pressure test yet.
