GT Turbo - Bluey Smoke!

Hi guys/gals...

 

As alot of you are clued up on turbo's i thought you may be able to help :lol:

 

Basically, the car is smoking from the exhaust quite a bit as though its burning oil...basically, you can accelerate normally on-boost, but as soon as you lift off and change gear, and power on again, there is a nasty puff of bluey/white smoke sort of 'spat' out...

 

I think it could be the turbo oil seals, but im not totally sure lol?

 

Anyone have any ideas?

 

Thanks!

Sounds very likely tbh. What gt turbo is it? starlet ?

Could be worth a look on the owners club sites.

 

Yes mate, sorry should of made that clear..:p

 

Im on the two main owners club sites, but they mostly chat rubbish all the time lol!

 

The turbo is being replaced with a TD04 in about 3 weeks, but just wanted to check that it wasnt anything engine side...as it could turn out alot worse...

 

Will it damage anything else..driving with dud turbo seals?

 

Thanks!

Id stay valve stem seals too. The reason you get smoke is that when you lift your foot off the accelerator there is a vacuum in the cylinders as the piston drops to the bottom. This sucks oil through the valve stem seal and then when you put your foot back on the accelerator, fuel is injected, combusts and burns the oil, then chucks it out of the exhaust!

It's more likely to be the turbo oil seal leaking under vacuum when you lift off. Valve stem oil seals will be more likely to smoke on start up as oil will have seeped passed them whilst the car has been sitting cold and this will burn off when started.

 

Turbo oil seals will often cause the symptoms you describe. Weeping turbo oil seals won't ruin the bottom end of your engine, only if it's burning enough oil to run the engine dry will it cause problems. Just make sure you check the oil level.

Just had exactly the same problem with my glanza.

 

Turned out to be that the breather wasnt allowing it to breath properly , although saying that mines quite highly tuned.

 

Heard quite a few people have had prob with turbo seals on the starlets.

Been built for circuit use, seam welded shell , cage etc. Was running a fully forged motor on a K3 turbo so once mapped was looking at about 275-300 bhp.

 

Although i blew the sodding thing up last week. So new engine is being built to run more boost aiming at a solid 325bhp. And weight to 900kg max.
