Rear main seal won't seal on 1999 TJ 4.0 due to scars on crankshaft

It leaks. Limped it back from Phoenix to Seattle . Dumped 18 quarts of oil in — most of that ended up in parking lots or the interstate. Otherwise, it ran great.

1qt per 100 miles. Got it to Boise and grabbed the trailer for the rest of the trip.

Yeah that’s more than a seeping rear main!! Repairs definitely needed! Sorry

I had a leak once that was about as bad as that. I got it after swapping my rusted oil pan. The cause was the oil pan seal not sitting properly in the channel in the rear main cap. I managed to get it to sit better, but still leaking, until I could get a new seal. Once the seal was replaced I was back to just the typical RMS drip.

First, I want to pass a huge thanks to @macleanflood . One of the straightest sharp shooters and generous people I've met in a long time. He stopped by and together we replaced the crankshaft. One of the kindest folks you'll ever meet.

So far, NO LEAKS!

The TJ is all buttoned back up and I now have 100 miles on it. So far, no oil leaks, and everything is running great.
