12 psi run and white smoke from the exhaust
Hi guys,
So heres the story. Car was running fine at 9psi engine strong and good runs. So i increase the boost to 12psi but at the same time I noticed that the HKS filter element had broken off and some ingested by the turbo so i took the intercooler off cleaned everything made sure nothing went through the intercooler and went for my 12psi run. All was good but in after the first run I saw a lot of white smoke from the exhaust so i stopped the car immediately. Brought it back and now when i start the car there is too much white smoke from the exhaust so I thought that I had blown the engine took the manifold off started the car was very loud and throwing blue flames but no smoke from the engine. Put the turbo back on and same smoke from the exhaust. Changed the turbo put a new one in and same smoke. Then I put in the stock sequentials and same smoke.
Engine is running strong with around 430mmhg at idle and no hiccups or bucking whatsoever
Where can this smoke be coming from as I first thought the engine and then the oil inlet on the single turbo but its the same with the stock oil lines with the stock twins. is there excessive oil pressure?
Any clue guys? What should I be looking at.
Thanks....

Thanks guys but I can see the oil if I take the downpour off I can see oil dripping from the hot side of the turbo and if I take the inter cooler pipe off I can see oil there. No smoke is coming from the engine as when I take the turbo off and start the car it there is no smoke but it seems like if is originating from the oil inlet but its happening on both the single turbo or the stock sequential.
I have an aspec gt3574r turbo kit with aspec 450r fuel system inter cooler. Power FC and koyo nflo and other stuff.

Yeah but I the smoke is white then it's not oil that's burning. Oil smoke is grey-blue and has a really distinct smell.
If what you say is the case, then your turbo seals are probably starting to go to and you probably are burning more oil than usual but if the white smoke is over powering that then I would say with about 95% certainty that your coolant seal is popped too.

I will make a video tomorrow and send.
If I have a blown coolant seal where would the white smoke originate from.. Wouldn't it come from the exhaust ports if yes then why don't I see any smoke when I start the car with the exhaust manifold off?

When I changed the turbos the problem still remains exactly the same.
I took the turbo off today starting the car only with the exhaust manifold on and kept it running for 8 mins no smoke whatsoever engine showing strong compression on the power FC at 430mmhg. Car starts in the first try even when cold. Why is there this excess oil pressure coming into the turbo single or twins doesn't matter. I can see the oil in the hot side and cold side of the turbo and there is a lot... This is on a brand new turbo as I changed the turbo thinking that I had blown the oil seal on the turbo which only had 800 miles on it....
If it is a blown water seal wouldn't it smoke even with the turbo off??
Please help....

Not to thread jack or anything, but will a bad coolant seal cause the water to bubble around the thermostat area causing it to overflow out the plastic reservoir? I have a buddy who's FD is over heating and a shop told him it was the seals, but i'm not seeing any white smoke come out of the tail pipe at all, at least during the 10 minutes we drove around in it. Any thoughts?

I have given above link to the video where I have taken off the turbo blocked the turbo oil feed line and started the car without the exhuast manifold just to reconfirm and there is no smoke without the turbo installed so I think this means that the water seals are ok....
why is this oil coming into the turbo single or twins do not matter I have tried 2 new single turbos and my good set of twins also but all,have the same issue oil starts getting into the turbo...
any idea any leads guys...

I also thought that was the case,when I switched to a new single turbo but then I swapped in my twins which were bone dry along with the stock,downpipe which also did,not have any oil in it and started the car without hooking up the down pipe to the mid pipe it still started smoking after 3-4 minutes and I took the,twins off and there is oil in them now????

aftermarket single turbos need a restrictor otherwise it may be pushing oil out of it.
the other twins, you say they are new but what is your idea of "new"?
where does the wetness stop in the turbos? after the turbine just into the downpipe area? inside the whole turbo exhaust before the turbine? inside the exhaust manifold? inside the exhaust ports?

Firstly thanks for helping me with leads to look for clues.
do you have any pic of what the restrictor looks like maybe I have it in the kit and am,not using it.
the wetness goes from the exhuast side of the turbo till,the exhuast tip and on the engine side it does not go upto the exhaust manifold. On the intercooler side now I see oil through the blow off,valve as well as in the intercooler.
the twins had,roughly 20000kms on them but they were taken off 6 months ago and did not have any oil or boosting issues.
thanks

My questions is why soo much oil in the turbo even with the restrictor and the engine has no smoke at all. Where could this added pressure originate from to get only to the turbo. Today I have all the oil lines off. The oil coolers off to check if there is any restriction.
Please help guys.... Thanks...
