HELP! Why are my new turbos smoking???

[green-lantern]

I'm assuming you didn't modify the oil lines? cus stuffing with these can cause too much oil flow which will force the oil through the bearings and it will smoke.

What are you talking about? stuffing?

^ Stuffing the return lines to increase oil pressure in the center housing??

Really? How is this done? In my opinion these cars seem to have almost too much pressure already.

By that I just meant play with/modifying them. If you change the size of these you will effect the oil pressure and flow. Seen this many times before. If you modify the oil lines from stock you will need to fit a restrictor to ensure the correct flow rate. Just poor choice of word

OK, I thought that might be what you meant. Witch brings me to wonder if my turbo return lines could be too small. I've had issues with oil leaks from my turbos exhaust seal side. I know my custom lines are smaller and I have wondered about it before but I still thought they were big enough.

This x2.

I have the 3sx stainless steel feed lines i believe...

Well mine are return lines. I could see smaller return lines causing turbo seals to leak but feed lines shouldn't effect the pressure too much.

if the feed lines are too big there is too much flow and this causes leaking around the bearings. too small return lines causes a restriction and has the same effect.

Well the banjo bolt and the rear brass fitting are the main restrictions so I wouldn't think that just bigger lines would make much of a difference.

EDIT: I do know that people can burn up turbos by putting restrictions in the feed lines trying to avoid leaking seals though.

Here is an update. I ran the car for 10 minutes (just sitting in the garage), rev'd it a few times during those 10 minutes. I didn't see any smoke. I don't think it got up to running temp, but for right now I think that's a good sign. Would you agree?
