Title: Garrett T3 wastegate getting in the way of oil return line
Post by: gnavs on November 07, 2010, 06:01:02 pm
Title is pretty self explanatory, I went to connect the oil return line to my NOS T3 and found that the "can" for the internal wastegate prevents me from mounting the return line flange.  I looked all over the wastegate and it looks like the cover is crimped in place, doesn't really look like it's meant to come off.  At this point I think I need to remove the wastegate just to install this line.  Has anyone else come across this?

I don't have a T3 I have a K24. You can't come straight off of it though. I went with a 45 degree fitting and converted everything to JIC. Also, you won't be able to do much of anything with the turbo mounted on the manifold and in the car. I don't know if that is what is going on, but I haven't found a way to do that yet.

it probably means you are trying to install it with the centre cartrige at a funny angle? are you using a standard VW manifold? Which way up is it?

Is the return a banjo type at the turbo or straight in?

Pics as requested.  you can see that the bolt hole nearest the waste gate can doesn't even line up.  I'm most likely taking my dremel to the can to clear up some space, unless someone else has a better idea.  I can't figure out how to get the wastegate off without destroying it.

I would guess that the center section is off a bit. And as a suggestion if you dremel take it off the oil drain part around the bolt opening. All that does is hold that piece down, it shouldn't seal at all. The wastegate is a trickier animal. Probably the best would be to rotate the center of the turbo, but if you have to dremel I would leave the can alone if possible.

OMFGENIUS!

That and I'd use a combination of vice grips and hammers over a dremel. Slightly misshapen would be fine, but a leaking wastegate housing isn't a good thing. Wait.. just realized which side that's on... yeah, not a big deal however it's modified.

I stepped back and looked at the entire turbo instead of just focusing on the can and flange and realize this is by far the best solution.  Actually, I feel dumb for not noticing it earlier.  :-[
