causing the oil too leak out a lil?? what causes that to happen

 

wait, are you telling us your header is hitting the oilpan? because if you are...isn't that clearly your answer? it doesn't seem probable that a header would hit an oil pan so much that it made a hole...but who knows. if you need us to diagnose your leak. it wont happen...you have to do it. we have no idea where the oil is coming from without seeing the car.
