anyone have premature seal failure on the PTE 6776BB turbo ? reason I'm asking I have a new engine/bb turbo with about 400-500 miles on them . Decided to do a oil change to 10/30 syn oil . took about a 1 hour highway drive into town and now I'm getting blue smoke . I can't see it being the oil and it being just a coincident that it happened at the same time . I dropped the syn oil and replaced it back with 15/40 dino oil and a fresh filter . but have no drive time on it . Heading to the track on Saturday . Very odd .
