2000 Volvo V70 Question: Turbo Noise
Answer #1patrick mannion from Greg Solow's Engine Room, April 29, 2011, 18:24Master
Don't wait for it to fail change the turbo use good oil preferably synthetic (due to high heat), on older Volvos it was important to change the oil feed line to the turbo if there was a failing turbo. Many good aftermarket turbo rebuilding companies out there that offer good rebuilt units. Try looking at www.rockauto.com or a website like "turbocity", don't know exact address for them I think they are in Los Angelas or Texas.
