I have a 283 that needs a new rear oil seal. I don't need to take the crank out, but would like to get this in. Can I loosen the bearing caps and raise the crank slightly to slide in the new seal? Then re-torque the mains. I believe this is a two piece seal.
Any tips I can use here is really appreciated.
Thanks,

Don't hold me to this, but I think there is a readily available one piece rear main you can stick in. This would of course require a naked crank flange to do.

Its difficult to describe but the seal to seal mating parts were staggered so that they were not in line with the seam between the cap and the block. I guess you could say the seam of the seal was at 2 o'clock and 8 o'clock. This prevents any oil from getting between the seal mating seams and leaking out thru the cap and block.
Its a small point but it was told me by a fellow who rebuilds engines in a machine shop. | | |

I would say the you could try it, but be prepared to go deeper when you do. | | |
