triple j Posted August 23, 2016 Share Posted August 23, 2016 U can't go off a post to diagnose your cars problems, the real proof will be in a compression test as said above. Quote Link to post Share on other sites
TimD Posted August 23, 2016 Share Posted August 23, 2016 (edited) You need to do some proper investigation as to what's causing it!! Do a compression test first and foremost, don't just replace piston rings for the sake of it. Did the turbo look like it had failed, did you even check? What's the inside of your boost pipes looking like, there could be oil in them? There are so many things it could be. Edited August 23, 2016 by TimD Quote Link to post Share on other sites
Ollieh17 Posted August 23, 2016 Share Posted August 23, 2016 Piston rings could be fine though and just have issue with an oil control ring Quote Link to post Share on other sites
paddy Posted August 24, 2016 Author Share Posted August 24, 2016 No oil inside the boost pipes, the turbo didn't fail and had minimal shaft play. After fitting the new turbo core it made no difference at all to the smoking so now sure it's not turbo related, it runs very well but don't see what else could cause now it other than the rings, everything else had been replaced Quote Link to post Share on other sites
paddy Posted August 24, 2016 Author Share Posted August 24, 2016 (edited) This is exactly the problem I'm having, will get it compression tested ASAP http://www.ukstarletowners.com/topic/101510-still-smokes-whenever-off-boost/?fromsearch=1 Edited August 24, 2016 by paddy Quote Link to post Share on other sites

jellybaby Posted August 28, 2016 Share Posted August 28, 2016 Cylinder leak down test will show the extent of piston ring damage etc if there is any but onlyDo that once u got the compression test Quote Link to post Share on other sites
paddy Posted November 22, 2016 Author Share Posted November 22, 2016 It was piston rings, now been changed running great with no smoke Quote Link to post Share on other sites
fiddlersport Posted November 22, 2016 Share Posted November 22, 2016 Was the ring stuck ? Quote Link to post Share on other sites
paddy Posted November 23, 2016 Author Share Posted November 23, 2016 Not as far as I know, I don't compression test it but after replacing loads of other bits it couldn't have been anything else, runs lovely now more still running in but defo has more of a punch to it. Was a easy enough job to just time consuming Quote Link to post Share on other sites
