I’ve had a rear main seal, or that is what it appears to be, leak since the new motor went in. My theory is the clogged separatir/rocker cover which was caked with burnt oil, caused excessive block pressure and blew it. The Valley Pan gasket was distorted up as well.

Since PCV valve mod it appears to be leaking much less oil. Only my observations, but there does seem to be significantly less oil on the ground.

I’ve yanked that SOB. At times I love LR for designing a great vehicle, then puzzle at things like that separator which is junk IMO.

I think it creates pressure clean or dirty, but that is simply an observation since I changed over to the PCV. The plate that sits under the to of the Rocker cover was totally caked with oil on mine. I DON’t think oil or much pressure was getting thru there.
