Hi everyone, now I've done the search and seen this an inherit problem that it's valve stem seals or turbo oil seals, as it is a bpu jap supra lol. Now my baby gets a bit of white smoke on a cold start up, stops after about 10 sec's. Now this happens on warm dry days so my hope of condensation has gone lol. Also I've noticed when the car has been pootling round town off turbos, so nice and hot, when I leave the car sitting for about a minute the blip the throttle to about 14/1500 rpm I get a bit of darker smoke.
Does this mean I will be waving bye to 4k for re-con tubbies and new stem seals. Also I don't really wanna take it off the road yet as its only really just got back on, but the car is off the road again in Oct for winter, so my question will I bollock anything up if I keep running it till then with them symptoms?
I know this question gets thrown about a lot so thanks for any replys.

the darker smoke will be fuel, the slight white smoke on start up, will probably be the stem seals, but you should not worry as you will have plenty of time to save up before they get much worse;)

I will film my supra on start up and you guys can tell me if I have the same problem I get a huge cloud of white smoke when I mean huge I mean when I start the car people who are sitting in the beer garden where it is parked start wafting it out of there faces.. Every one tells me its condensation, I do have quite a fat exhaust 4" mid pipe 5" back box, so I would guess there is more room for a bigger condensasion build up

Think it's only condensation when its pretty cold or wet fraid to say. Mine hasnt got to that stage yet where you need to waft. As Gaz said valve stem seals mate part costs about 23p labour costs bout 900 :( if they have to take the head off some people on here have devised away if your good with a spanner and peice of rope.

i noticed mine doing it for the first time friday morning, my car has 80000miles on it, i had this week off so havint used the car all week and i jumped in it friday i started her up and pulled straight off, (normally i seem to sit there for a short while before i pull off). there was a pretty decent blue cloud behind me, ok after, one thing ive noticed is i use my car every day to work and back 20mile round trip and it does not smoke on start up at all if i use my car car everyday, only if its been parked up for 3days+, oil level is always spot on, i remember my old xr2i used to do it. dont think its much to think about to be honest, its an engine at the end of the day.

Trust me mine is worse than than lol, i wouldnt worry to much just might be worth getting the stem seals done at some point in the near future.

p.s that burble sounds awsome

looks like stem seals, condensation would usually smoke (white) longer

General rule of thumb is:

Burning Oil - Blue Smoke
White - Condensation/coolant
black - fuel

smoke in the 2nd vid is condensation

08-06-08, 15:56
Is it using collant?

Yep looks like stems seals but not too bad as mine has deteriorated quickly within the last couple of months and now smokes when pulling away from traffic lights once its nice and warm.

The first vid seems to be stems seals by the way the smoke shot out...seemed like kind of a build up...:blink:

The second vid is condensation, mine is like that, just gently wafts into the air...only in cold weather, the condensation shows up...:)

what I will do is leave it over night then start her up tomorrow morning and do another recording, is the stems seals worth getting done, I found the guide on how to change them, looks way to tech for me but I would be willing to give it ago... I think

Bugger that mate! Im reasonably clue'd up on cars but not that technical!
I know its a lot of cash but, if i were you, i would leave that to someone who knows exactly what they are doing lol...:)

yeah, bloody supra's! If the stem seals have gone and I have a oil leak, Once I get them sorted the next thing will be the turbos! Is the Stem Seals a Must to get done or is it ok for a while?

Tbh Lew, stems seals will be ok for a while. If your Turbo seals are on their way, get them done first as you dont want to cause more damage...
Do you have blue smoke under boost??

bmx1lew
09-06-08, 01:55
no no sorry I mean once thats sorted next it will be the turbos... its like a never ending list of maintenance but I should of new that when buying a L reg car, cant complain when you compare it to other L reg cars.

Honestly and truly, just buy a 5 litre container of decent oil and just enjoy the car, most smoke a bit once de catted, the lack of back pressure and some (normal) wear in stem seals or turbo seals causes it. It could go on for another 50,000 miles like that, no worries. Just check the oil level and slap in a bit of synthetic every now and then as required.

Not yet, Its really bad after sitting for two weeks and struggles to start but day to day its almost fine bar a few puffs here an there.
I really want to have a go at it myself but were moving house soon so would be best to wait.
I'll try some different oil next service its running Mobile 1 (15w/ something or other) at the moment.

well left my car from the friday morning when i took it out, till monday morning 5am to go to work, its daylight at that time so could see tidy and my car did not smoke not even a tiny bit, same again stared her up and pulled off, no smoke, my stem seals cannot be that bad, maybe just alittle worn, overall very happy with the car, 3months of great ownership so far:)
