Big Red One Posted April 29, 2008 Share Posted April 29, 2008 when i start the supe up from cold i get a big puff of white smoke so i think its valve stem seals, is changing the stem seals that big of a job and how many stem seals is there to replace and how much are they Link to comment Share on other sites More sharing options...
Scott Posted April 29, 2008 Share Posted April 29, 2008 There is a tutorial on doing the whole job including pics etc. If you do a search you should find it no problem. Link to comment Share on other sites More sharing options...

Stem seals i think is blue smoke = Oil... Link to comment Share on other sites More sharing options...
bodilx6 Posted April 29, 2008 Share Posted April 29, 2008 Valve stem is a definate blue smoke at start up. Also when you move off after a red light or so after the engines as been running with vacuum. But alway blue smoke. White is water/vapour Link to comment Share on other sites More sharing options...

Keep an eye on your oil though... Link to comment Share on other sites More sharing options...
flukey-lukey Posted April 29, 2008 Share Posted April 29, 2008 Valve stem seals is a white puff of smoke, not blue. Blue would be turbo seals Link to comment Share on other sites More sharing options...
Scooter Posted April 29, 2008 Share Posted April 29, 2008 Valve stem seals is a white puff of smoke no d; blue = oil burning whether oil stems seals or turbo seals..... white puffing is water and just condensation unless your coolant is disappearing......

Fifty Posted April 29, 2008 Share Posted April 29, 2008 Blue I like mine actually brings a bit of extra color to the mornings. been like it for 5 years at least - go figure Rich Link to comment Share on other sites More sharing options...

No way! lol, I've read on here loads of times white smoke = valve stem seals. I'll get some examples and post the links Link to comment Share on other sites More sharing options...
flukey-lukey Posted April 29, 2008 Share Posted April 29, 2008 ahh you know what, I can't be bothered to trawl through all the forum. So white smoke (not steam) is not valve stem seals? Link to comment Share on other sites More sharing options...
Rayman Posted April 29, 2008 Share Posted April 29, 2008 I thought blue poof on start-up was vss's and blue poof on boost was turbo seals Link to comment Share on other sites More sharing options...
Scooter Posted April 29, 2008 Share Posted April 29, 2008 just didn't want folks thinking theirs had gone The supra creates a lot of white smoke on a cold start which is often commented on by new (and anxious) owners.........99 times out of 100 its all just normal condensation.

Rayman Posted April 29, 2008 Share Posted April 29, 2008 Of course most supra exhausts are massive and makes it look worse. Link to comment Share on other sites More sharing options...
Fifty Posted April 29, 2008 Share Posted April 29, 2008 I was thinking how many cc of oil from all 6 cylinders would it have to be to cause a visible puff of blue - not bleedin much eh?:d Rich Link to comment Share on other sites More sharing options...
Guest DaveWilko Posted April 29, 2008 Share Posted April 29, 2008 I get the puff of blue smoke on startup and check my oil every week. The level has hardly moved in over a month. An its definitely valve stem oil seals. Its not just Supras it happens to. Mk3 escorts were notorious for them going Link to comment Share on other sites More sharing options...

Big Red One Posted April 30, 2008 Author Share Posted April 30, 2008 what ever the weather is i still get a big puff of white smoke but it is only on start up after that i get nothing, it must be condensation then, i have got a blitz nur spec exhaust system on the supe will that make it worse Link to comment Share on other sites More sharing options...
bodilx6 Posted April 30, 2008 Share Posted April 30, 2008 I thought blue poof on start-up was vss's and blue poof on boost was turbo seals Yes, thats right. My understanding is that a bit of blue smoke on boost can also be due to VSS in conjunction with the blue puff when starting up and moving off after idle. I can't exactly explain it but several people have solved all of the above with fixing the VSS. If you dont have blue smoke ever on startup or when moving off but only on boost and let off, then its definately the turbo seals. ahh you know what, I can't be bothered to trawl through all the forum. So white smoke (not steam) is not valve stem seals? No way. Think of it this way. If you pour water on a fire it will give off white smoke = moisture. If you pour oil or other fossil fuels on a fire it will give of a big puff of black/blue smoke. When you've got busted VSS'es that does't seal properly, oil is drawn through them when the engine is running on a vacuum, which is fx when you are stopping for a red light. When you move off this gets burned off. More or less the same thing when starting the car up. I thought white smoke on start up especially when its very cold, is condensation in the exhaust...no?? White smoke will usually be condensation. Like you say in cold or moist weather. It CAN be water from the cooling system if you've got fx a blown head gasket, but other things would probably have caught your attention as well.

It doesnt help with a big exhaust exit hole... My exhaust i think is near 5.5 - 6inches big...so i get quite alot in a very cold morning! Link to comment Share on other sites More sharing options...
Terminator Posted April 30, 2008 Share Posted April 30, 2008 How long does the "smoke " last after start up? It is the same amount of smoke after every cold start (i.e. overnight)? Does your cooling system pressurize too quickly, ie pressure in rad before the engine and water is hot? Link to comment Share on other sites More sharing options...
Mike M Posted April 30, 2008 Share Posted April 30, 2008 Will leaking stem seals cause oil mist to spray out the BOV? Link to comment Share on other sites More sharing options...
Guest DaveWilko Posted April 30, 2008 Share Posted April 30, 2008 I think thats more to do with a fault in the breather system. I need stem seals but i get no oil from the BOV. Maybe one of the more techie guys can confirm that Link to comment Share on other sites More sharing options...
SilverSoop Posted May 1, 2008 Share Posted May 1, 2008 How long does the "smoke " last after start up? It is the same amount of smoke after every cold start (i.e. overnight)? Does your cooling system pressurize too quickly, ie pressure in rad before the engine and water is hot? Well when i started the supe yesterday, as it was cold and wet, it lasted until i set off...I usually let the supe warm up a bit - roughly around 4-5 mins before i go and still white smoke was coming out. As soon as i went though, it dissapeared. Probably heat and the exhaust gases, got rid of the excess vapour in the exhaust... Link to comment Share on other sites More sharing options...
bodilx6 Posted May 3, 2008 Share Posted May 3, 2008 Will leaking stem seals cause oil mist to spray out the BOV? Hmm.. good question. I'm guessing no. To my knowledge its completely normal to have a bit of oil from the BOV. If you have more than just a bit (not more that cans simply be wiped off) you might have trouble with your turbo seal and you will also have more that just a thin film of oil in the IC pipes Link to comment Share on other sites More sharing options...
