Idk going to just put the oem water pump in and hope it fixed it. If that doesn't work i'm just going to take the head off and check to see if it's warped. The oil isn't milky or anything. I've had royal purple in it oil is super clean when you check it and stuff. But once you took off valve cover it had all pitch black oil and really thick lucas oil stabilizer type stuff on the valve cover etc. I cleaned up all the oil out of the head cleaned all the cam caps etc so there's no oil and stuff in there.... Now that i finish typing all that, the thick stuff on the valve cover was kind've green, Like anti freeze color... I don't think it's the head gasket cause there's no type of smoke or milky oil etc and there isn't any loss of power.
