When I pop opened the hood again this morning, there's oil over the top part of the heat shield again. This is the third time that this had happened to me, and I'm really sick of bringing the car back to the shop (yes, it is under warranty). <p>So are there any high quality aftermarket gasket that can fix this problem once and for all? Is chipping one of the caues? (I have Wett 1.0 bar)<p>Thanks<br>Kev
