so by doing the opposing blade only it should keep the overall balance? I was hoping that the damage was considered small, but this topic isnt covered too often. i'm just trying to fix it while its open if it will definitely be an issue.

Jerry knows his stuff. Be careful not to screw any others up.

Yes the idea is to keep the blade in balance. I have done it with chips three times that size. Turbos provided years of service and still tight.

You should really have it balanced after you clip the opposing turbine wheel. It will be unbalanced, but the more balanced it is, the less problems you'll have with the seals & shaft play in the future.

by balanced you mean actually taken off of the turbo and balanced? or just clipping the other side to try to balance it as best i can while its on the car?

The first poster who suggested clipping was not making reference to you doing it yourself. Clipping a turbo wheel is a common practice, but it's done with equipment that clips all the vanes exactly the same amount. It permits the extra back pressure to go by the wheel with less restriction in the high end of the RPM range. It just happens to be in the same area as your lost part of the vane, which part would be removed anyway. Your choice, I just wanted to clarify for those who may not know that information...

by "undo water and oil lines" what does that exactly mean? i understand that the lines feed the turbo, but arent they always filled? If i take it off wont it leak everywhere? ..or just whats in the line itself?

sorry for the newb question, i just dont want a surprise

The oil drains down the oil drain pipe, and there's just a small amount in the turbo when the car is not running. You can catch it in a 12 oz cup.

Similar for the antifreeze. Keep the feed line pointing up and you'll lose even less.

I would not do this if I was you. Turbos are balanced at high speeds and operate at high speeds. You are trying to balance something yourself that will spin greater than 100,000 RPM.

well there is always tolerance in balancing, i know it wont be 100% perfect, but i've got to try something.
