Bad smokin!!

Afternoon All,,,, a buddy of mine has a 99 7.3, he just replaced the turbo, CAC tubes were all full of oil and it was smokin bad,,, new turbo, runs much better, but still SMOKES like a chimney!! WTF idling no to minimal smoke, driving,,, way bad,,, drank about 2 qts in 20-30 miles,,, the tube from the drivers side valve cover full of oil, pulled it off, blowin smoke,,, is it ring time? about 150k on it,, but he did have a K&N and had lived on a dirt/gravel road for about 6 mos... he was going to pull the valve cover and start it and get back to me,,, any ideas

Thanks

Wish I had more experience to offer some advise. Here is a bump for you.

If you take the oil filler cap off and lay it upside down on the filler neck while the truck is running will it stay there or does it get blown off? If it blows off it starts to look more serious.

What color smoke? And lots of oil in the CAC tubes (with a stock CCV) means lots of oil getting sucked out of the CC. Probably from blow-by. Do a compression test...

Nice colors in your avatar.

Ignore the smoke out the oil fill tube and check for pressure. Smoke is fine, pressure is not. K&N's don't play well in front of a turbo. Do you know if the oil in the driver side tube is new or old? Any oil dripping out the exhaust? Any chance the intake is plugged up?

if the tubes were full of oil, not just residual oil the first time, the turbo seals let loose

if the blow by tube on the drivers side valve cover is full of oil or drips at any steady rate and has pressure of any kind, time for a ring job

I would hope a "new turbo" wouldn't have let go already. But you never know. A lot of hours sucking dirty air through a K&N could've eaten up the rings, so that's why I say a compression test is in order. That's what I'd do, given the intake isn't restricted.

If it is not leaking it out somewhere external and you are absolutely positive that the new turbo is not the source of the oil consumption, then it's time for a rebuilt engine.
Again, if it's not leaking externally and the new turbo is not leaking, all that oil is being blown out the breather and into the intake due to rings not sealing.
The cylinders are too worn to just throw rings in it and be done, you have to bore it out with new pistons.
