Oil leak, rear main?

[MarkTX]

02 6speed 117000. oil leaking from inspection plate. more on starter side than other. I just had pass. side valve cover gasket replced and no oil in valley or coming down the back of motor. If in fact it's the rear main any idea how much to have it replaced?

It's highly doubtful it's the rear main. I've only hear of one other 7.3 with a truly bad rear main.
It's either the O rings on the high pressure oil lines or the O rings that feed oil to the turbo bearing.

When I had the valve cover leak. Iwas told they never go bad. I looked at the back of the motor as best as I could and didnt see any oil drooling down also valley seemed to be oil free. I'll take another look. Thanks.

check under turbo really good.

I looked in 7.3 tech files to get a better idea where to look and I could see pass. side of the pedestal and it was dry as a bone. To much stuff in the way on driver side to see. I'llcrawl under it tomorrow as I'm now cleaned up after yard work. Appears to be pretty dry under though.
