BlackWatch66 Posted April 16, 2009 Share Posted April 16, 2009 I know smoking exhausts have been extensively covered and have read many threads, but I need to clear up a problem I have; I went out for a spirited drive tonight and all was fine until about an hour in when I noticed smoke behind as I was going along, I pulled over and there was no smoke, so I blipped the throttle and absolutely vast quantities of white/light blue smoke literally billowed from the exhaust, and then settled again until there was no smoke on idle. From reading the threads I gather this is either valve stem seals or something is up with the turbos? can anyone point me in the right direction of what this could be and how do diagnose what it is? BTW it is a 1993 jspec TT auto with around 40k miles on the clock recently gone BPU. Please help!!!! Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted April 16, 2009 Share Posted April 16, 2009 Valve stems normally smokes on initial startup and idle, or 'over-run' I would be inclined to say turbo oil seals. What is your spec and modifications? Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted April 16, 2009 Share Posted April 16, 2009 Sorry, spec is in the sig It would be best to take it to a local trader, perhaps AFR if it is close enough, they could then identify the specific cause. Its no good me guessing Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted April 16, 2009 Share Posted April 16, 2009 I would say almost certainly turbo/s oil seals. Quote Link to comment Share on other sites More sharing options...
Homer Posted April 17, 2009 Share Posted April 17, 2009 Oh dear, from the symptoms that does sound like a turbo failure AFR will be able to diagnose and repair to your requirements Quote Link to comment Share on other sites More sharing options...
