Gar_GT4 Posted November 9, 2013 Share Posted November 9, 2013 this is going to be a bit hard to explain but here i go...have a tt supra with very few mods, double decats, exhaust and intercooler. the car has 114k km on the clock. i service it reguarly using millers 5w40 oil and i always warm it up and leave it a minute on the turbo timer. over the last 6 months or so ive gotten puffs of blue smoke from the exhaust. the weird thing is it might only happen once every 10 times i drive it and doesnt happen at any particular time...once was when i was pulling away hard, once was just driving normally around town, once was slowing down for a roundabout and the most recent was sitting in traffic where i could see and smell the smoke coming out and it only did it for about 10 seconds then cleared up. there is a big period of time between these incidents aswell. since then it hasnt happened since. it coming up for a service now and it hasnt used a bit of oil...still full and clean...i havent looked into it yet so i thought id ask to see maybe it could be a breather problem hopefully. thanks Quote Link to comment Share on other sites More sharing options...
scott87 Posted November 9, 2013 Share Posted November 9, 2013 Blue smoke is oil. Im sure a tt owner will come on here and list the things to check first.... Quote Link to comment Share on other sites More sharing options...
chris0132 Posted November 9, 2013 Share Posted November 9, 2013 Mine does it all the time and is the valve stem oil seals they cost about £70 for the parts then the job is not a fun job lol Quote Link to comment Share on other sites More sharing options...
jcbt Posted November 9, 2013 Share Posted November 9, 2013 This is probably turbo seals as valve stem smoke is usually just on start up Quote Link to comment Share on other sites More sharing options...
drew 007 Posted November 10, 2013 Share Posted November 10, 2013 As said it could be the valve stem oil seals or the turbo and as said if its on start up a puff of blue smoke normally indicates valve stem oil seals are leaking and if its when the car is warm it could be the hot side seals in the turbo.?

I'd say turbo seal as VSS would be on start up as previously mentioned. Do you use it regularly ? How long does it stand in between uses ?

Gar_GT4 Posted November 10, 2013 Author Share Posted November 10, 2013 It never does it on start up...even with the colder weather...I drive it maybe 3 times a week and the round trip into work would be about 60 miles. ..been driving it more now just to see and hasnt happened...been told it could be little valve on the breather system Quote Link to comment Share on other sites More sharing options...
