Smoke from front of engine (m57) 2010.

[Diesel Spectre]

I’ve been at it for about 40 min. per evening this week (all the daylight I had left after work). Lower turbo was hung but not tightened. Oil return line (lower half) was installed and tightened. New DPF was installed with new gasket and new clamp. I installed the lower turbo oil feed line but it’s still loose because I’m not happy with how it went. I got (2) tubes of liqui-moly turbocharger breakin additive but it looked like it mostly wanted to run out. I should have added it before I pushed it up there because the Feed hole is on the side. I tried carefully rotating the compressor wheel to “suck some into the journal” but it didn’t work. So I’m looking for a way forward to properly pre-oil the turbo. I could try to fill the oil feed line but with the hallow (banjo) bolt attachment it’s not practical. Any ideas? At this point I’m just making a bigger mess and that liqui-moly stuff is like never-seize. It gets everywhere and end ends up all over everything in the area, including yourself. Maybe if I had a syringe and a small plug, it would actually go in. I’ll try to pick one up at the local drugstore. Any other ideas are welcome.
So the DPF is tightened to the turbo and I will replace the urea metering valve in the first exhaust section. Then I’ve just gotta install the new O2 sensor and both egt sensors in the DPF. The O2 sensor is a wear item and I understand the egt sensors really don’t go bad but I beat the wires on them up pretty hard taking the old dpf out and I figured it wasn’t worth fighting to get the old ones out of the old dpf. Next is the low pressure egr cooler, then I can tighten up oil drain line clamps and I’ll be done laying on my back in the driveway (once I get the subframe back up, engine lowered back down, and all the plastic shields back on). Then I can get to the metal charge piping between the turbos and start working on the upper turbo replacement. Of course we currently have 4 inches of snow on the ground so I may spend this weekend getting started on the upper turbo anyway. It’s too cold to be laying on my back in the snow. Once the heat gets sucked out of me, my hands no longer want to do what they’re told. Haha. So it’s 20 minutes under, 20 minutes getting warmed up so my hands work again.
As far as the “spacer ring”, I did almost forget to install it. Borg-Warner ships new turbos with a protective “bag of expanded foam” that is molded to the bottom half and the top half. The ring was under the turbo and almost completely included in the bagged foam shipping protection. I just spotted the shine from the metal and thought what else would come with a new turbo. Sure enough, that was it. Went and looked at the old one for orientation and you really can’t screw it up. Just have to remember to use it. Without that piece there, the changeover valve will never be able to do its job. Again, vigilance is best when you’re this deep into it and you don’t do it for a living. A questioning attitude and slow path forward (no matter how tedious) are going to help avoid the typical sanfus.
Back at it today but with the snow, I may not have any progress.
With the complexity of this task, I really wish I could delete it. It would substantially simplify this job and make it much more reliable (as well as far less expensive). Oh well, outside of my control.
Wish me luck.
