oh and when i accelerate i can also hear a gurgle sound underneath.. i was just thinking aliens were under there sucking away my antifreze..... i guess not........


Gurgling sounds when revving the engine (w/ the heater valve open) were always a sign when I had HG leaks. NEver saw oil-coolant mixing. All the times I had this type of problem, it was always an exhaust->coolant leak except the initial time when it was a cracked head, in this case there was also coolant->exhaust leak and I would get lots of white smoke. But mainly it was the case of exhaust gas over-pressurizing the cooling system (and that exhaust gas making the gurgling sounds) and blowing the coolant out the overflow.
