Can't remember, but are the holes in the crankshaft for the flywheel through holes? Are the cork pieces for the pan gasket installed? Did you use any sealer? Is the valve cover leaking at the rear? Oil pressure is not likely to cause the rear main seal to leak. I have observed what seemed to be oil in the driver's side of engine. It is very important to note that these fault codes should only be considered as potentially related to a bad rear main seal if you are experiencing an oil leak from the area between the engine and transmission where the rear main seal is located. Works on 1994 thru 2003 Ford 3/4- and 1-ton trucks with 7. Oil leaks in old cars unfortunately come with the territory. Correct installation of the seal will insure leak free engine operation (Fig 36). The crankshaft bearing rear seal allowed air to leak in and thin the air/fuel/oil mixture. The other option was a low-friction replacement seal. Your trip must have seated in the seal. At the very rear of the engine block the crankshaft runs very close clearance to the block and main bearing cap. Make sure your crank will work in the block you have.
