Usual suspect would be turbo oil return line. O-ring at the bottom cant last forever and needs periodic replacement. Never done it on 2.9, but cant imagine it being much "fun". Parts are probably $10, but without lift it is an interesting journey from above relying on your dexterity and praying for top bolts not to fall..

Well thank you for that info, only good thing about the bolts is that it has been in the garage and taken care of very well so. It leaks like crazy as well cant even see the turbo from top or bottom, you recommend from under cause I do have a lift for use. Thanks again
