jSbr0 Posted July 1, 2014 Share Posted July 1, 2014 Hey guys Basically i was driving along going from 4th to 5th and a puff of blue smoke came out the back between the gear change I have done a bit of searching and there is talk of valve stem seals But only just over the last week my turbo has been making a whining noise as it starts to boost and hesitates when i first take off after starting the car (not thrashing) Now ive taken the piping off and there is a bit of blow by in the pipe before the turbo The turbo is clean but does have shaft play 1 second in out not sure if this is normal How else can i check to make the turbo hasn't gone bad Do i need to drop the exhasut side off Link to comment https://www.sau.com.au/forums/topic/445106-rb25det-turbo-or-something-else/ Share on other sites More sharing options...
75coupe Posted July 1, 2014 Share Posted July 1, 2014 Is there any evidence of the compressor fins hitting the sides? What boost are you running?
