7.3 Leak... Looking for more info...

I have just finished reading Mary's thread on diagnosing common 7.3 oil leaks and the leak that I doesn't seem to fit those described... So I was wondering if anyone could give me some additional insight before I take my truck in to the shop on Monday.

The leak loses about 2qrts a week... not sure if this is fast or slow, but it seems to be coming from the back side of the engine block hitting the ground between the oil pan and transmission.

There isn't a lot of oil on the ground so there it isn't a free flowing leak. Any thoughts to help educate me would be appreciated.

Could be your turbo pedistal O-rings leaking. Have you looked up top in your valley yet? It could also be your rear main seal.

so far at 183K had to replace turbo o-rings both sets, o-rings on plugs in high pressure oil rail, and ebvp leaks a little, also ccv bolts backed out and started a nice little oil slick, but 2 quarts a week? that sounds like turbo o-rings.
