I want to be clear that while I did have two issues with the turbo he delivered, he did indeed deliver and was willing to take it back immediately to make it right.
Note the following Pm started by him;
Did you bolt up your turbo yet? I need you to do me a favor. Apparently I got some housings with my builds that were machined for use with 60-trim compressor wheels. It will be easy to notice - look inside the inlet of the turbo. Look carefully at the clearance between both the inducer and exducer against the compressor housing. If there looks to be a gap larger than the thickness of your fingernail, the housing is bad.
I apologize for any inconvenience and the shop is getting me the correct housings this week. I guess they make some frankenstein turbos with the Volvo housings, and some of them got mixed up. Let me know and I'll take care of it (I'm assuming the easiest way is to just send you another compressor housing?). Thanks!
Here is my PM to him and his response regarding the oil smoking issue;
So since the turbo was already installed and my 850 was ready for a first test drive I went around the block. Lots of smoke in boost and slight smoking on decel (likely residual from when in boost).
Swapped my 15G back on, once it cleared out the smoking stopped and car runs fine.
So looks like this turbo has further issues beyond the compressor cover.
Here's vid of the car after I got back from the test drive [youtube link]
monkey my life. Haven't seen that yet!
Ok...send it back to me. It will be fixed immediately with the correct compressor housing. You still have the address?
It's been a week since I sent that and hadn't heard anything so I just swapped to my other turbo and sent this out for rebuild to a local shop. It's rebuilt and back on the car as of last night and smoke free... they re-machined the compressor cover for me too (provided a good 15G housing i had) so I'm out $200. Review with your builder and let me know how you want to proceed.
Last communication was June 9, it's now June 30. I understand those who are out cash and have nothing in hand but for my experience he did seem genuinely concerned and willing to make it right. Still willing to give him the benefit of the doubt.
