Bad Oil Leak - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My brother has a 1984 C10 with the 305 and we've replaced the rear main seal twice now because it leaks oil so badly out of the little hole in the bottom of the torque convertor cover.

We made sure to RTV everything good and we put a one piece rubber gasket on the oil pan and it still leaks like crazy. As soon as you stop a puddle starts to form under the truck. We used a 2 piece rear main seal.

Did we do something wrong when we replaced the seal or could it be something else thats leaking?
