Rear Main Seal

[Gearhead999]

You shouldn't have to move bell housing. But, use the lip seal. Knock the pin in on the bearing cap and index the seam of the seal so it doesn't match the seam of the bearing cap to block. Make sure you put the seal it the right way. I have removed way to many installed backward. Also, it is good insurance to replace the rear main bearing, upper and lower, at the same time. This keeps the crank from moving around from wear that can cause the new seal to fail premature.

Not a hard job on a Mustang. Just very messy. Also, good time to check the oil pump and screen, maybe upgrade. Keep everything very clean and scrap the gaskets good. Glue the new gaskets and end pieces to the block and put alittle, and I say again LITTLE, RTV at the joint where the end rubbers meet the cork gasket. If you put to much it can squeeze into the oil pan and clog the oil pump screen. Not a good thing to have happen.
