i think i'm leaking from around the exhaust manifold but i dont know what. It looks like oil but the motor is so saturated with it i cant tell what it is. It feels like oil my oil is black. It does smoke from only around the headers though. my oil pressure gauge will bounce when I turn the key on. after it starts it will go back normal. The coolant gauge doesn't work at all. the breather tube from the exhaust has a white grayish smoke like if you spill oil on the motor. its on the number 1 and 8 cylinder.
