Review on Fel Pro OS30594C Oil Pan Gasket by Matthew Riley

The gasket is made of a cork like material. Due to the screw hole pattern, it only goes one way. The blue striped side goes up to the block and the smooth side goes down to the palette. The gasket was not exactly square and had a notch about 1 inch on one side. I had to use a couple of screws to hold the gasket in place on the pan as I lifted it onto the block. Be sure to apply oil to the sides of the seal when installing.
