Hi Guys,
I have a 428FE with a bad rear main seal. I am now on my second set of new rear main seals just trying to put the upper half round in. I removed the main cap and pushed the old one out without issue. Every time I push the new one in it stops about half way in and then will only go in if you push really hard. This destroys the outside of the seal and it still will not go all the way in. Any ideas? Should I loosen the reat of the main caps? I really would not like to do that. I have oiled up the seals and I made sure everything is clean.
