I have just what the title says not sure what to do never had this happen before. I drained the radiator and it looked like mud coming out. So I thought blown head gasket. So i drained the oil and it looks normal no anti freeze at all. I have never seen that before and I am not sure what to do. I know it is coming from the #8 cylinder as you can see in pic. Is there something else I should be looking for or is it the head gasket??? Intake and intake gaskets looked fine. Please help am stumped.
