Repeatedly Blowing Oil Pan Gaskets: Here's whyThere are very few reasons that you could be blowing oil pan gaskets. One of leading causes of blown oil pan gaskets is excessive crank case pressure. This is more common in cars that come from the factory naturally aspirated, and have a turbo kit added on later. Excessive crank case pressure can often be alleviated by adding an extra breather to your valve cover.
| Another possibility is that your oil pan itself is warped or damaged. Use a straight edge to make sure that all sealing surfaces are flat, and there are no gouges or knicks. If you do find nicks or deep scratches on the pan where it bolts up, you may consider having it resurfaced at a machine shop.
Lastly, OEM or even aftermarket oil pan gaskets are a waste of time. A generous amount of Black RTV Silicone on the surface of the oil pan where it mates to the block is more than sufficient. . . and it's much easier than lining up a flimsy paper, or rubber gasket. (and cheaper) |
