I too had the same problem and had to replace my turbo. It was real bad...people in other cars would back off. I had some time to shop(extra car) and found prices from $1000 for a new one (Garrett) to $200 for a used. United Diesel in springfield va. is a place I have used for 20 years for IP pumps and injectors and the owner told me that buying a used turbo "was like buying used food". He sold me a reman from Garrett for around $600 with tax, and was the same part # I had on my car. He will ship to you also, if this tubo doesn't hold up...but it sounds like you might have gotten lucky. Good Luck.
