So like the topic asks...
Does anyone think a -3AN feed line for the turbo is too small? Please give reason as to why you think it might be too small as well.
I am having a bunch of problems with a smoking turbo. My seals are pretty much shot on the turbo which is causing this. But the turbo is brand new, well about 6000 miles on it. But still, it shouldn't be bad yet. Anyhow, there is a ton of shaft play and the bearing is certaintly damaged.

Any advice?

Oh, I have a -12AN drain line. THe i.d. on the 1/2" drain fittings is 7/16" if you guys are curious about that. And the drain is a straight as possible, although not perfectly straight.

Thanks!
