Sound like your exhaust is like mine 4 inch turbo back

Last time I had it off It did drop down alittle and I wedged a board on the frame under the exhaust pipe to help hold it up when I put the marmon clamp back on really wasnt to bad

If you had a helper for a second it would be easy

 

Crankcase pressure can easily be measured with a manometer and the right vent tube. This would take the rings or cylinder walls out of the guessing games. Test,verify,repair.

 

Do like bismic said in his first post. Pull the downpipe and look for oil. Plenty of flex in it to get it back on. Also take a mirror and look in the exhaust side of the turbo for oil "swirls". When i deleted my cat i also noticed more smoke. I figure if it starts and runs i wont worry about a little blue smoke.

 

I will take the downpipe off tomorrow and see what I find. I'm now getting oil residue on the outside of the tailpipes and some very thick, sludgey oil is collecting inside the exhaust tip. It doesn't smell like diesel, just oil, and only started noticing this recently. Is the CCV reroute just a band-aid for excessive blow by?

 

The CCV reroute is not a band-aid for excessive blow by, it is to get rid of the oil from inside the intake, and intercooler. If you have ever taken it apart you would see why it should be done, it is sounding like the turbo needs some rebuilding, or replacement

 

I noticed a few puffs of blue smoke a while back as well as oil at the seam of the exhaust tubing. I attributed it to bad turbo oil seals and proceeded to rebuild the turbo. Changed oil at the same time from T6 to T5, 15-40. The blue smoke is quite a bit less, but still shows at idle and not all the time.

First start up of the day, slight haze. I leave the house when the oil temp gets above 100 and drive easy until it gets to 160. I will get a pretty good train of smoke until the oil temp gets above 180 at every stop while I'm idling. When the oil temp gets above 180, it will only smoke every 3rd or 4th stop at idle. If I hold the brake and get the RPM's over 1,000, the smoke dramatically decreases, if not completely dissipates.

I do have the CCV rerouted and am wondering if it is affecting the operation of the engine.

Any thoughts?

 

Sorry, that was supposed to be a new thread.
