Help! Smoke From Exhaust With New Turbo

[B-Man]

When I was birning white smoke (under decelaration ) it was oil seal in turbo - Scary shite when you see all that smoke coming from your rear end.

[jazza08]

mmm im hoping its not that How much did your's cost to re-do the oil seal on it? Or did ya just replace the turbo

Turbo had about 15,000kms on it from rebuild and seemed like new, just seems odd to be that...

I had this problem with my car. it ended up being the bottom end its weird and it would blow HEAPS of white smoke on idle yes ??

Did this happen as soon as you turned the car on ? or only after you got it tuned ?

hi mate, my r33 started bowing puffs of pure white smoke at high rpm which progressively got worse till it blew smoke all the time and at idle.It ended up being two pistons which had cracked on the side letting oil in.

$900 for a new core for the HKS 3040

Its nothing to do with the motor as it started when the new turbo was installed by a mate who im starting to think didn't know what he was doing... i asked about the oil restrictor in the turbo line and he wasn't too sure what i was talking about, maybe the turbos b/bearings are being flooded by oil!

Will find it out tomorrow/friday when the turbo's taken off and the lines are checked.

GCG quoted me around $550 for a new oil seal in the turbo, more money lol

From the info you have provided - my bet is on the turbo. I would only ever buy a new turbo - unless, I knew and trusted the person I was buying it from

I'd be double checking the oil venting issue.

You know the hoses to the can were to restrictive before, but now with nice big ones you still have the problem? How about you remove them all and go for a little run.

Then stop and open the bonnet and see if its smoking like a chimney. Its worth checking just incase its your rings. Done a comp test?

Is this a new turbo because the old one let go?

[jazza08]

Compression is 150 even across all 6 cylinders as of 3 weeks ago.

The old turbo had a problem with the bearing so yes thats why i changed it! As i said i had zero problems (smoke wise, bearing on old turbs was rather loud lol) before this turbo went on, the new catch can deals fine with ne blow by the engine may have.

The turbo was bought from someone i trust and is very well known on the forums which is why im not convinced its somethin to do with the actual turbo itself, plus by looking at it and checking shaft play the turbo appears to be near new.

I am having the oil lines looked at, the one to the turbo to check if it has a restriction piece in it and to make sure the oil return to the sump is not blocked and all is hooked up correctly, as i said the person who did it told me they knew what they were doing but now it appears they're abit iffy on some issues... it was probably installed incorrectly

[jazza08]

Just for reference here is pictures of the catch can, the smoke has nothing to do with this set up.

I ran the car with the old set up and it produced more smoke, then ran it without anything on the head and it reduced smoke, with this in place its the same as with nothing on the head (ie no restrictions)!

Plz not outlets are all blocked except lines to catch can which is why i needed a breather in the system

For those who have watched the thread,

The turbo was taken off today and had no restrictor on the turbo's oil line so it was flooding the b/bearings with oil hints the smoke in the exhaust.

So fingers crossed a restrictor on the turbo stops the oil smoke, will find out either tomorrow or monday

good to hear

That will definitely be your problem then.

Just realise that your whole exhaust system and muffler is probably now full of black oily residue. Expect to still see some smoke for a day or two at full throttle. That will quickly go away.

So don't get a fright when you see some more smoke first time you drive the car !!

[jazza08]

I got a call today that said they did find a 1.3mm restrictor in the oil line... so unfortunatly its back to square one.

There is some oil in the intercooler piping from when the catch can set up was without a breather which is being cleaned out now however that its been suggested once again its the turbo seal.

Once the car is dyno tuned if its still smoking after a week or so i will get it taken off (for about the 3rd time!!!) and have the turbo pulled apart and replace the oil seal on it as they told me the turbo appears to look good from the outside but you can't know unless you open it up.

I was so excited aswell lol
