2001 7.3 Leaking Oil And White Smoke

Curious if anybody could help solve issue with my 2001 f350 7.3. wit 96k miles on motor.

This morning I found some oil under my truck , looked further to find oil also around passenger side bottom of motor, just a bit. While leaving this morning truck began to blow white smoke and seems to have lost a little power. All fluids are fine, not overheating.

What is wrong, turbo??

What are signs of bad turbo??

Thanks.

EDIT
Fluid on bottom of motor is a tin oil, more black than brown and not as thick as oil.

If you've got anything looking brown coming out the bottom of your truck, that needs to be addressed.

Tailpipe is dry but oil film along tailpipe walls.

If it's leaking at the base of the turbo, it should be running down the back of the engine and on the ground under the torque convertor. That doesn't explain the white smoke though.

If you remove the down pipe from the turbo and there's oil in there, your turbo's likely shot. Check how much play the turbo shaft has. That too is an indicator.

Is it coming out of the clamp that holds the down pipe to the turbo?

Around clamp is all dry, clean. Just the turbo base is oily.

There are seals in the turbo shaft. If they blow, oil will either blow out the exhaust side or it will blow out the intake side of the turbo. One way will just blow the oil out the exhaust pipe. The other sends it through the motor then out the exhaust pipe.

Sounds like your EBPV actuator in the pedestal the turbo sits on could also be the culprit. John is also correct in that the seal inside the turbo on the exhaust side could have failed and is now producing the white smoke out the exhaust. This will usually not manifest itself dripping down the back of the engine, though. The failed actuator in the pedestal, however, will send plenty of oil to the ground via the back of your engine. In addition, the oil could be coming from the high pressure oil lines or the high pressure oil pump itself. You need to climb on top of your engine and look down into the valley. Is the front of the valley under the fuel bowl dry? If it is, shine your flashlight slowly toward the back until you see moisture. Once you have done this, post back in here with the results for more help...
