[Vwdiesel] [TDI-conversion] Turbo rebuilders? (KKK K14)

[Shawn Wright]

Ok, got it apart again. Lots of oil on both sides. I didn't think about positioning the seal rings 
with gap at the top until Andrew mentioned it, but both sides were close to the top somehow 
by fluke. I measured ring end gap, and the new rings are between 0.15 and 0.20mm at both 
ends. (same size rings). I broke one of the old rings to use as a scraper, but the other old one 
is tighter than new - less than 0.15mm endgap. Maybe this turbo has between machined with 
larger rings? Nothing else unusual. Drain is clear. Hmm... I just checked the other end of the 
line into the pan by blowing into it, and got some backpressure, then poof and it went clear. I 
waited a few minutes and tried again, but the slight pressure from oil in the line is much less 
now. So it seems there may have been something in the line. 
The bad news is pulling this turbo apart again has further damaged the turbine shaft around 
the seal ring, as I don't know how to get it in place since there is no room to compress the 
ring. I managed the first time, but now it doesn't want to go. 
I suspect I will be pulling this turbo again soon. I've been quoted $300+ for a rebuild 
depending on extra parts needed. If anyone has a line on a *new* turbo, K14 or similar, 
please let me know. At this point I would consider a new unit just to avoid further hassle. 
Thanks
