Hey guys!

I just fired up my rebuilt b16 turbo. Problem is that i've got lots of white smoke on idle and when i hit the gas it turns to a big cloud of pure white smoke. After driving the car for like 10mins i turned it of and saw that there was oil coming out from the turbo's turbine. I've had no overheating problems or what ever. The car runs great when you drive it (but it looks like your bringing bad weather whit you).

- So what i've done is that i retorqued the head (made no DIFFERENCE).
- Tryed to put some bar's leak in the system to see if it would help (made no DIFFERENCE).

So is it bad rings or headgasket?

Appreciate all answers and proposals!

br, Jesper!

 

saw that there was oil coming out from the turbo's turbine...

That seems to be a clue. Investigate more into the turbo.

 

Either the oil pressure at the turbo is to high or your return line is no good. What are the sizes of your oil lines ? Post some pictures of your return line to.

 

Can the high oilpreasure couse the heavy white smoke?

 

Like Rich was saying if the drain is not good enough or if too much oil is supplied then it will blow by the seals and cause this type of smoke.

 

If it's to much oil blowing past the seals then you risk damaging your turbo. I'd recommend likewise, check your oil feed line asap.

 

Took some pictures on the feed, drain and the oil train today. When i removed the drain tube from the oil train it started to flow oil out from the train, can this be a problem?

 

Yeh , its suppose to literally fall out the Turbo into the sump. It probably backing up somewhere.

 

Would a oil restrictor be a good thing to try?

 

What does the return line look like when fitted.? What is the inside diameter of the hose?

 

It's an 45 degree AN8 fitting with stainless steel tube. Dunno the dia on the AN8.

 

I'm pretty sure you need 10an at the minimum. Looks like that, along with maybe how the return line is routed.

 

Sorry my bad, i have AN10. My oil resistor i'm using atm that followed on with the oil feed kit is 3mm. Think i read somewhere that it's suppose to be 0.063"?

Here's a pic:

 

Make sure there is no kinks in the line

 

3mm is almost twice as big as what you normally want with a journal bearing turbo. Your right .063 is about right. It would be good to know what you oil pressure is also. If it was smoking as bad as you say it was it might need a rebuild on the turbo.

 

I really dont hope i need to rebuild the turbo since it's new :/ Well i'll find out later today if my problem i solved!

 

Did a comp test on the engine today, showed 115,120,130,90. Bad gasket i guess? Do you think i need to copper spray my OEM headgasket?

 

Okey, today i picked the head of. The cylinders looked great BUT the exhaust channels was full of unburned oil and the downpipe was also full of unburned oil. I also checked the IC pipes, there was not a drop of oil anywhere! My money is on that the turbo is done? What do you think?

Here's a pic on the pistons after i pulled the head of. As you can see there's no burned oil or what so ever!

 

The exhaust "channels". Do you mean exhaust ports of the head? Also those compression numbers are really low.

 

Maybe I am way off here but I don't think so..white smoke is always coolant I thought? oil is bluish not white..

EDIT: just read your post about compression...Blown headgasket I think. Do a leakdown test.

 

Oh i forgot to change those comp numbers, should be: 140,150,160,150

 

Yeah i mean the exhaust ports in the head. I checked the intake side too but that was clean. I gave the wrong comp numbers, shuld be 140,150,160,150

 

Can i have bad valve seals? Couse i get alot of preesure under the valve cover? And that would also explain the oil in the exhaust ports of the head right?

 

Pictures of the turbo, kinda oily! Downpipe was full of oil.

 

bad turbo
