Abz Posted January 25, 2014 Share Posted January 25, 2014 That sounds like turbo oil seals to me. I'd be thinking this too, the smoke tends to appear once the engine is warm. Normally the first tell take signs are when you get a puff of smoke on over run or idling. I'd take James advise & have a look in the inter cooler pipes for oil first.

FOSTA Posted January 25, 2014 Share Posted January 25, 2014 Yep turbo oil seals, I has this with 2 different turbos on my old car. Just smell the smoke and you will smell if it's oil or not. My clothes where always stinking of oil when I used mine with failed turbo seals. Quote Link to comment Share on other sites More sharing options...
Tsia Posted January 25, 2014 Author Share Posted January 25, 2014 Yeah, I had the almost exact same thing on my previous Supra. I'll tell you what, this twin turbo system is a right pain in the arse! Assuming it is oil in the pipes, I might just have to single it and rid myself of a turbo Quote Link to comment Share on other sites More sharing options...
DodgyRog Posted January 25, 2014 Share Posted January 25, 2014 Looks like Oil smoke to me as well, it would disperse if it was water based It's probably been puffing for a whole on lift of and you just have not noticed Quote Link to comment Share on other sites More sharing options...
Tsia Posted January 25, 2014 Author Share Posted January 25, 2014 Seems likely. I guess I'll tear the turbos out and take a look-see. Anybody know if it's possible to discern which turbo is the issue? Quote Link to comment Share on other sites More sharing options...
cainhead Posted January 25, 2014 Share Posted January 25, 2014 Does it continue or clear after running? Only ask as my blows scary amounts of white smoke on star up but clear after a while? I was thinking stem seals but not sure after seeing this. Quote Link to comment Share on other sites More sharing options...

Yeah mate yours sounds like VSS's to me And Tsia when your driving about and the cars warm does it do it all the time even before number 2 turbo comes online? If so might be the first turbo.

Tsia Posted January 25, 2014 Author Share Posted January 25, 2014 That's a point. I'll take it out for a quick drive tomorrow and get a friend to follow me, see if we can diagnose it. I'd hazard a guess at it being turbo 1 though, due to it smoking on idle. Quote Link to comment Share on other sites More sharing options...

drew 007 Posted January 25, 2014 Share Posted January 25, 2014 If it is the hot side seal in the turbo it won't smoke on cold start up but as the car comes up to temp and you use the turbo/s it will then start to smoke once you reach this point the car will smoke. Either way you have a turbo/s problem. Quote Link to comment Share on other sites More sharing options...
Tsia Posted January 25, 2014 Author Share Posted January 25, 2014 Yeah, I've replaced turbos from this before, it's not cheap. I'm undecided between tearing the turbos out myself, sending the faulty one off for repair and then re-fitting them, or just biting the bullet and starting a single build.

Nic Posted January 25, 2014 Share Posted January 25, 2014 Any thoughts? My first idea was turbo oil seals, but they were only rebuilt 20k miles ago by CR turbos. Still a possibility I suppose.. Are the turbos still under warranty? it's not uncommon for rebuilt turbos to go prematurely. Quote Link to comment Share on other sites More sharing options...
Tsia Posted January 25, 2014 Author Share Posted January 25, 2014 Are the turbos still under warranty? it's not uncommon for rebuilt turbos to go prematurely. 20k miles and it's changed owners twice since they were done, 4-5 years ago. So nope Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 25, 2014 Share Posted January 25, 2014 Thanks for the advice on that. Do you mean VSV's? TSIA - sorry for hijacking your thread. Will stop now! VSS= valve stem seals. Pretty common on 2JZs Quote Link to comment Share on other sites More sharing options...

Pretty common on 2JZs Are ok, thats what i had been told previously it might be, so nice to get the same opinion from a couple of people. Getting it booked in for this next week.

I was thinking stem seals but not sure after seeing this. Valve stem seals failing are blue smoke and shouldn't smoke anything like the op's video, with valve stem seals failing you get a few seconds on start up. Are you sure your smoke isn't possibly condensation ? this tends to happen in winter. Quote Link to comment Share on other sites More sharing options...
Tsia Posted January 25, 2014 Author Share Posted January 25, 2014 Regarding the turbos: 1: Is the first turbo the one towards the front of the car? 2: Is it possible to remove this by it's lonesome? Quote Link to comment Share on other sites More sharing options...
Pulley Posted January 25, 2014 Share Posted January 25, 2014 (edited) As Dnk says, valve stem seals don't smoke/steam like this on idle , usually a few seconds the clear and then usually show signs on over run This looks like steamy to me Place a rag or old t shirt over the exhaust when it does this then see how much oil is inthe rag, or if its just sooty water Or get a pint glass and hold in the flow of the "smoke" and see if you get lots of condensation If the cars been on a reasonable run and upto full operating temp then you shouldn't get much water I suspect it's a coolant leak / crack in turbo cooling housing or elsewhere Edited January 25, 2014 by Pulley (see edit history) Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 25, 2014 Share Posted January 25, 2014 That is definitely smoke and not condensation. Quote Link to comment Share on other sites More sharing options...

Pulley Posted January 25, 2014 Share Posted January 25, 2014 I'd do a compression test/ pressure test You can buy the kits to use on a compressor to check for hg failure If it is steam and not smoke then it's just a process of illumination If its smoke, I'd check your crank breathers first, then the pipe that feeds into the inlet If you give your car a good motorway junction run to make sure any condensation in exhaust and in the crank case have been burnt/evaporated off Then let it sit at idle and hold a glass in the "smoke" and also smell the smoke It should be obvious if its steam or smoke from oil Quote Link to comment Share on other sites More sharing options...
Tsia Posted January 25, 2014 Author Share Posted January 25, 2014 Thanks Pulley. I'll get on to that tomorrow. Anybody have an idea which is the first/second turbo? I can't remember if it's the front or the 'back' one that comes on first. Quote Link to comment Share on other sites More sharing options...

And I believe the first turbo is closer to the front, second is closer to the driver. They are sequential so my guess is that they come off together and cannot be seperated unless out of the car, or not at all??? Can somebody confirm this?
