White/Grey/Blue smoke, thought egr / oil in charge pipes, turbo seal?

Im getting smoke after the truck is warmed up and when you rev only a bit of smoke comes out but once you let the gas off alot of smoke comes out. Also smokes alot while your driving and not so much when at idle and sometimes even goes away at idle.

Pulled the charge pipes about to tear down for egr cooler delete and noticed alot of oil in the charge pipes and inside the manifold. Could this be the cause of the smoke?

Also parked the truck on a hill and pulled the egr valve never noticed any coolant in there. Theres puddles of oil at every connector, lookes like fresh motor oil, brown not black.

Any word of advice?

Also had the egr unplugged and revved the engine and noticed a fluid come out the tailpipe??

Thanks

bad egr cooler will cause coolant out the exhaust. The oil in the intake manifold and IC pipes is from the CCV vent

yeah well the smoke does have a tinge of blue to it kinda grey too and it doesnt smell of coolant just diesel.

just trying to figure out if its a turbo seal, leaking injectors or the egr problem.

Check your turbo over carefully when you have it out. If the bearing seals have failed, oil will leak past into the exhaust side as well as the intake side to cause the smoke you describe.

Ive checked seals on other turbos by wiggling the shaft for end play and side play. Similar fashion for diesel turbos?

Ill pull the turbo right now.

Thanks.

Yes. The Ford workshop manual specs. for acceptable turbo shaft endplay and radial play is 0.091 mm (0.0036 in) for the endplay, and 0.5 mm (0.02 in) for radial play. If either one of those dimensions are exceeded with your inspection, you'll need to replace the turbo or the center housing rotating assembly.
