I took off my intake pipe from the turbo, and found oil on the inside of the intake and oil around the blades. Not much oil, but enough. Where can I get a new turbo?

It may not be as bad as you think, try replacing the oil return first, then clean the intercooler and all piping and see if that helps, as it may just be blowing oil because it can't drain back. The line is a cheap fix, don't use radiator or fuel, use hydraulic line.
Is there wobble of the impeller, or end play, if so it may be soaked and need rebuilding.

I was very satisfied w/ the rebuild service I got from Dallas Turbo but be sure to send them your wastegate actuator also so they can check it. I did not and I think mine is bad.
Also, if you catch it before it is real bad, they may be able to salvage the impellers and only have to do seals!
Mine was let go by the previous owner and it chewed up both impellers, so all they could salvage was the case and wastegate.

Good luck, there are others, but I haven't any experience w/.

How much did they charge to do your turbo?

Don't hold me to it, I have had so many parts to replace so I'll have to chase down the receipt.

I just looked around and don't find the receipt, sorry, and my purchaseagen/bookeeper/wife is out of town so I can't ask her either!

Like I said, mine was absolutely shot, about 2 quarts of oil in the I/C, took out the cat, ox sensor, and was a fxxxxxxxx mess!

Email Mike@dallasturbo.com or call 800-297-3626, he seemed like a real straight shooter

Thanks for the reply. Mine isn't bad but I'd like to have an idea of what it's going to cost down the road. Is lasting 170,000 miles good for the T-25?
Who has had their tubo crap out and at what mileage?

95000 miles, rebuilt and uprgraded by turbochargers.com, $875 only because of the shot turbine housing.  Happy with service, payment methods are kind of a pain in the ass.  COD or You have to fax them the front and back of a credit card and your signature or some crazy shit.
