I would say oil starvation due to banjo bolt and restrictor.

Man I miss my 1.6 HKS manifold, such a piece of art! Are you sure you never sucked in some of that silicon sealant I see at the inlet?

Pretty much all oil feeds come in from the side to feed the top port, as it would put quite a kink in the hose if it came straight down into the feed port and then bend it to clear the hood.

Yeah, I have. As long as it's a real Garrett CHRA and you haven't tried to disassemble it for any reason, they'll replace it regardless of the damage.

I can't imagine the turbo was under-oiled. I run an .035 restrictor and so do a lot of other people, and there aren't a rash of failures like this. My bet is that because you've got the boost controller hooked into the intake manifold, it's overspinning the everliving **** out of the turbo and causing your failures.

Should the wastegate line be hooked up post intercooler/pre intake?

I mean that it appeared from his first picture that the oil was coming in sideways. Like yes, the line comes in from the side, but makes a turn and goes downwards. You can't have the oil shoot in from the side, continue to keep going along the horizontal axis, and then continue out the drain on the other side. The oil still needs to fall in a vertical axis.

Couldn't be this. The problem is in the bearings. Beside this my 2nd turbo hadn't any silicone sealant.

Ok , in the 1st video you can see the drain, nothing, not a single drop..

In the 2nd video is the oil feed, it fills 0.5l bottle in a few seconds with and without the restrictor.

Sorry for the poor quality , it's from my mobile.

Any suggestions?

Yes propably, could you figure out why? Is it possible from dirty oil?

What's on the end of that oil line? Did you check flow through the restrictor? Look at the restrictor and see if there is damage or possibly an error with the machining ... does the hole go all the way through?

That would eliminate the restrictor if it flowed the same. What did the two failed turbos have in common? same oil? same drain?

He has the line looped though. Remember it's only gravity carrying the oil away. It's not going to make it's way up that loop.

Gianic, try it again with the bottle under the oil pan.
