blowing smoke on boost, 1ggte, clean motor!

[IN 05 NT]

hey guys,

within the last couple of days, the 1ggte has started to blow a BIT of smoke (easily noticeable in teh rear view!)

when booting it in 2nd-3rd (and higher gears) it tends to put out a stream of white smoke, definatley oil, (can smell it!)
but doesnt blow any smoke when driving it easily up the revs with no boost,

the motor is only a fresh one from SSS autos, and had a leak down test of 5-10% through out! (was an excellent motor with only 80k on it!)

also done the hill test, held it in 2nd gear going down a hill then booted it at the bottom,.....it doesnt hesitate or blow out a puff of smoke

it still comes on to boost early, round 2500 -3700 is full boost, and holds 14-15psi well (when its cold it spikes to round 16psi, and hits the fuel cut defender (evil thing! )

i only just fitted a oil catch can yesterday (non breather type) and so far the clear lines are still clean of oil, (none has been through them yet!),
and the lines it replaced was the line that goes from just behind the oil cap filler, then over towards the turbos, (that line was a solid rubber line with no breather between it?)

the oils is still clean and the motor would have not seen more than 3000ks since ive had it in,

AND YES I SEARCHED BUT COULNT FIND ANYTHING ABOUT COMING ON BOOST!

so what do you guys reckon? does it seem that the turbos could be rooted? (stock turbos)

cheers, blake

Hey,

have a look at your brake amster cylinder, it could be leakking into the booster and then going into the motor. Had this happen to a VL turbo, you would boot it and it would piss out white smoke, replaced the master cylinder and it went away.

sounds strange i know, because on boost the one way valve to the booster will be blocked off, but just going by a previous experience. and i thought, OIL was blue smoke, black is running rich, and white is a fluid


cheers

sounds like a turrbo seal! new oil might be a bit thicker and putting pressure on the seal!
seal on one of the turbos is prob leaking a bit under higher loades when you have max oil pressure and boost!

[30psi 4agte]

Yeah i would say turbo seal.

After a squirt if you pull up at lights does it still smoke abit?

Pull out plugs and c if they are oily. This will give you an indication if the oil is being burnt internally or not If they are clean it would be fair to say thatit is coming from turbo..
If you can pull off dump pipes and check for oilto see which turbo it is.

[sanchez]

i've had the same issues that you've described and it turned out to be a leaky seal on one of the turbos.

[Endless]

Yep sounds like the symptoms of leaky turbo seals.

[EldarO]

white isnt oil smoke...

still, if its happening on boost, its obviously turbo issue, most likely the seal...

warranty for teh win...?

Im getting this issue too not tooooo bad .. but its there (prolly just running rich like all toyos ,

but my smoke is not so white, more of a grey ....


mine is prolly turb seals too

Another thing to check will be your Intercooler piping. My mate had a paseo that had the same prob when it boosted it put out more smoke than a steam train. Turned out to be massive blow by and even after we fixed that all the oil in the intercooler and piping kept feeding it so to stop this all the piping had to be cleaned. Give that a go as well.

hmmm,

the oil that went int o the motor was a thin highflow oil, special for turbo's, i hate the stuff, its too thing and the tappets tap like mad, needs thicker oil, keeps it quieter!!!

is there one seal between the turbos or 2?,

and are they a bitch to get to?, as i might just hold off till i get the single kit i bought,

cheers fellas for the easy info!!!

oh shit, the cooler and pipes will have a coat of oil in them aswell aye?

just another thing to add to the list, things to repair, replace,

Use a bit thicker oil maybe? You wont need to run stupidly thin oil in your 1G-GTE... especially in Australia! It's a fair bit warmer over here remember

I'm voting oil seals still. Each turbo is a seperate unit - you will have to choose between a 2nd hand set of 2, a rebuild of your current ones, or a single. I'd go for the single, if you have money to spend on it. Rebuilding them isn't worth it imho. 2nd hand is OK if you have little money to spend and want to get the car back on the road, minus smoke.

hey yeah, i thinkj i'll just hold off as i bought a singke turbo kit off purplesive,

so stuff doing the seals i think,

yeh id have to say turbo seal matches the best in this case...

it'd be the seal in the exhaust housing of one of the turbo's, leaking oil into the exhaust turbine... they'd be two seals for each turbo wouldnt there? one to stop oil getting into compressor housing, and one to stop oil getting into exhaust? plus a bunch of others doing other jobs?

the turbo's are a bit of a pain to get out. and that was out of the car on a stand. u have to remove the piping, then the oil drains and lines, a few of them tuck under and around and stuff, so getting them off with the very little space you have left would make it a whole lot harder... ohh, and even with it all off, the flange bolts are such a pain to get to and undo, i couldnt see it happening easily if at all in the engine bay of a celica...

i wouldnt worry to much about it, as long its not using to much oil. just try to hold out till the new single jobbie goes in

[EldarO]

beware that while putting a thicker oil in may stop the problem for a while, it'll just come back, except that youll need even thicker oil next time, and it'll just get progressivly worse and worse.

obviously, if youve gone for stupidly thin oil (no insult to your inteligence intended!) then yeah, going to a "normal" weight oil will help.

although the only way to fix it properly is to get new seals put in, although it looks like you have an idea in mind anyway
