talked to precision again today about my pt52 failure....and they said they would warranty it even though it was past warranty because it wasnt my fault...had it for about 8 months but only has around 6,000 miles on it.....they said i had wear on outer thrust bearing which lead to stress on the compressor side turbin...basically he said to get a blow-off valve and it wont happen.....so i guess im gonna get ATR's blow-off valve.....im just glad to hear i dont have to pay to have it fixed!!!!
