After about 12-15,000 miles on a rebuilt TE-44 turbo after a year of use, the exhaust journal was worn down really badly according to Majestic Turbo in Irving, Texas (www.dallasturbo.com) and they want $415 to fix it . I already paid $450 for the limit engineering rebuild..akh i'm pretty bummed considering I always used 10w30 synthetic oil and changed the oil religiously. Any advice?
