Oil is not harmful, but could indicate a leak from a blown seal.
If the blades are touching anything it is junk. Sorry.

Re:Turbo junked????
well jeff has not marked a few and they still kick.
it is very important but u can get by without it, basically u could get shaft wobble, which cause bearing wear, which leads to turbine hitting the housing, which leads to the darkside.
anyways.
to clean it i use my glass bead booth. another good way is to use some gasoline and a tooth brush..

Re:Turbo junked????
Agreed, my T3/T4 on my car right now, I didnt re-align the compressor blade with the shaft, because my mark got washed away in the solvant tank, lol.. But shortyz is right, you want to re-align them the way you take them off for proper balance. Or, you could just take the compressor housing off, get some brake clean with a toothbrush, and you will be fine.
I've also had a few turbos that touched ever so slighly on the compressor housing, and didnt have problems with them at all. Once oil is filled in the center section, it takes a little bit of play between the bearings.

That's crazy. I could see the oil taking up some of the play, but I don't know. That's like living on the edge. __________________

Check this site out. http://www.roadraceengineering.com/i...bowarranty.htm
Some shaft play is normal, some oil leakage is normal, alot of either is not so good. Turbo balance is critical, that's why turbo rebuilders spend $50,000.00 and up on computer controled ballancers, so there rebuilds will out last the warranty. Don't disassemble the rotating assembly unless you have to, clean it as a unit with brake clean and a tooth brush.
