DaveA Posted July 1, 2020 Share Posted July 1, 2020 I get a puff of blue smoke after turning left. Here's what happens. I'm well on my way to work, mostly at 70mph. I turn off the A road to go through a housing estate which has a long downhill stretch so mostly on over-run. I slow right down for a slow left 90 degree corner and on steady acceleration, not booting it, I get a quite sizeable puff of blue smoke. It's exactly the same most mornings on this corner and I've noticed it elsewhere, mostly after a slow left turn. I have an A3 8P1 2.0 TFSI BWA. The car runs like a dream, it least I don't notice any lack of performance. It has PCV delete, de-cat pipe and chip mods. Does anybody have any ideas? Thanks in advance.

Magnet Posted July 2, 2020 Share Posted July 2, 2020 Hello Dave, I don’t know about the possible effects, if any, of all your ‘deleted’ bits, but your description of blue smoke on acceleration after overrun is text book valve guide/stem seals wear. Connection with turning?? Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted July 3, 2020 Share Posted July 3, 2020 I reckon the problem is more to do with acceleration after a period of over-run, than it is to do with the turning, so valve seals are going to be a prime candidate for the cause. 1 Quote Link to comment Share on other sites More sharing options...
