This is a newb question... but I'm some what a newb and I would appreciate some help....
Ok so I need a little help with my new SR swap. I swapped it in last weekend and finally had it running. It ran great, pulled hard and sounded extremely healthy. I continued to drive it the rest of the week and then I noticed that I was gradually getting more and more bluish smoke out my exhaust. Then by the end of the week it was pouring a good amount on a cold start. Obviously there could be many things wrong. I'm thinking the turbo seals are shot. I had oil in my hotpipe when I took it off and also a good amount in the outlet tube. The car still sounds healthy and pulls really hard. I also noticed that my return line IS kinked. Either way I'm pretty sure it's my turbo. Should I just buy a new return line and see if that fixes it or are the seals shot and should I just buy a new turbo? This seems simple when you read it, but considering I live three hours away from my shop (where my car is currently sitting) and I have no internet access out there, it's not something I can just look at or fix whenever I want to.
If someone has a link to these same symptoms, just go ahead and send me the link please...

If its getting into the compressor side, seals are more than likely done. But fixing the kink wouldnt really hurt. Might alleviate the smoke some, atleast let it be drivable without being too obnoxious.

Yea that's what I figured. I wasn't able to get the car up and get the exhaust off to check unfortunately. I'll go ahead and replace the line but I realized another problem. The return tube is rubbing on the steering rack. Can I just reroute it with different tubing or what? I haven't heard a lot of people running into problems with the stock t25 oil return lines rubbing on the rack, mostly just people who upgrade their turbo's with bottom mount mani's.

I'm having the same issue with the steering column knuckle in the way. Is there a special type of hose that the return line needs to be. I'm going to need to find a hose with a 90degree bend to go around the column. Any suggestions anyone..

In my case, it turns out I actually had a T28 not a T25, they sell return lines on FRSport. That's the route I ended up going. It is still close but fits perfect and I haven't had any issues with it since.
