ok so i just changed my rear main seal on my 1999 7.3 and im paranoid its still leaking, but its on the passenger side and i think its actually leaking up above somewhere. it appears to be running down the up pipe on the passenger side but i dont no where its originating. the valley is dry. turbo??? it honestly looks like its coming out where the up pipe joins into the turbo...maybe thats my smoke problem too...
help please!

Yeah, sounds like it is time for a turbo rebuild/upgrade.

Turbo seals will cause the problems you're having.

I'm having the same issue. I have drips, but the valley is dry. I'm beginning to think the o-rings in turbo pedistal.

7.3Ls have weep holes in the back of the engine block that allows 'stuff' to drain down.
