Good morning. Need some input on replacing the rear main seal on a ford 841 gas. We have swapped it out about 5 times now and still leaking. first two seals were A and I, next one was thru case and the last one was a felpro. It seems like the seal is just hardly contacting the crankshaft but probably is more then it appears. the case fit a little tighter and the felpro better yet but it's still leaking. We've tried flush with the block seam and also clocking the seal away from the seam. Cam cover is dry, We put a fine film of rtv where the cap meets the block and the cap seals seem to be installing as they should. What else are you doing to make these hold. We are using the neoprene type C shaped seals not the rope ones
