I put one on last fall specifically to correct a blowout of my previous rear pan seal (4 piece) after about 1 hour of engine time after my rebuild. Since I was specifically pulling the engine to correct this problem, I saw this new seal as a godsend. I had one of the 1st batch - their timing was perfect.

This new pan gasket is great and metal reinforced in all areas except the rear (round) area. Since this was my problem area, I contacted BOP for some pointers for installation. They advised me to glue to rear part of the seal to the pan with weather strip adhesive, assemble loosely and then let the sealant dry overnight. Then the next day I applied some silicone in the 4 corners of the pan and I have been good to go ever since.
