does this look like it could be a blown turbo oil seal? Lots of smoke.

Black smoke- extra fuel
Blue smoke- oil
White smoke- coolant

Can't tell from the color in your video. Which is it?

Typically you'll see signs of a failing turbine side oil seal on decel. When oil pressure first drops a small amount of oil will seep p past the seal and burn off.

If it smokes constantly the seal has already failed.

We need a better video taken from behind the car to see what color the smoke is.

Just to add to this if blue /oil smoke is coming from the catch can that is due to rings/valve seals and not an oil seal? Since the oil seal for the turbo would make it only come from the exhaust correct?

ek9_beast

Bad turbo seals shows through the exhaust only. Correct..... If that catch can situation is what is going on for you then a simple leakdown test would tell the story

My guess would be a cracked piston as soon as vaccume hits its pulling oil into cylinder

Sorry it took so long to get back... oil is blue and only seems to happen after i let go of the gas...

roll8221

And seems to happen more the higher the rpm and oil pressure

Dr Drew

Take the oil return line off of the turbo/oil pan and look through it to make sure it is open and not kinked. If you are using E85/Ethanol based fuel, enthanol in the oil can swell the rubber (if it isn't compatable) in the return line and restrict flow.

it's either a turbine side seal failure warning, a return line issue, or a piston problem.

roll8221

If it was a piston problem, would I notice issues with the way the engine is running, like fumbling or running rough? I have also read on here that the b18 should have a oil restrictor with a pt6262, though the manufacturer says it shouldn't. could a 0.065 restrictor correct the problem? Motor has less than 50 miles on it. Tuner pointed out that the drain line was incorrect, I have since fixed the drain but is still smoking. Not as much as it was, but still smoking...

ek9_beast

Not having a restrictor may have caused the seal issue... If so the damage may cause a new seal replacement and restrictor at the same time.. But in your case its blowing by the turbine(if that's the problem) so a restrictor may fix the issue, so yes its a possibility

Also, what's your vacuum at idle?

roll8221

That's a good question, when i bought my gauges i got just boost instead of vacuum/boost.

ek9_beast

They're cheap and vacuum can tell u a few things about motor health. Ring seat.. Fluctuations indicate issues. Many different symptoms show through vacuum

roll8221

I'll see if I can grab one, thanks for all the help, I'll try to post back with any results...

ek9_beast

Good luck. Def post results so others can benefit from this in the future

roll8221

I haven't gotten the vacuum gauge yet but I'm pretty sure it's the seal... i took the downpipe off and you can see oil on the bottom of the inside of the turbo...

ek9_beast

Yea definitely get a vacuum gauge but sounds like the seal

wantboost

iTrader: (2)

That could be valve stem seals, turbine oil seal, or both. Either way you don't need the gauge now.

ek9_beast

The gauge isnt necessary for this situation now but for the price, the gauge is worth having. Certainly can't hurt for future reference.

Thanks again for the help...
