This did a good job of sealing the floor pan of my 2002 Ford Ranger XLT 4.0 SOHC. I checked them daily for leaks on every ride. The bottom tray is easy enough to make. that I took the risk of using this gasket in hopes that it would permanently seal my engine. Unfortunately, I now believe the top pan seal is another source of leakage and there is no way I would ever touch this PITA! Looks like this truck will live to the end of its days with a small oil leak. :(
