Hey guys,

I've read countless threads on the subject. I even had a smoking problem after my TT was installed (Smoke under deceleration, Fixed by making true dual and correct oil level) Ive always noticed a small amount of smoke under hard acceleration at WOT. I know the gravity feed oil return lines suck ***. Could this be another problem other then just the oil return lines? I notice the smoke a lot more on an inclined on ramp. Other then WOT there isn't much other then just a really faint smell of burning oil (no smoke visible). I'm pretty sure its the turbos over oiling and blowing through the seal on WOT. Any opinions?

Also, anyone ever use a puller pump, bigger return lines, ect to fix the oil return problems with APS TT?

Thanks

 

The APS TT kits are very sensitive to oil level, and the angle of the drain lines. Make sure they are trimmed sufficiently.

 

^ they are trimed. I only put in 5 qts of oil.

is some smoke on accelleration normal on an APS TT Z?

 

it is only under WOT? my guess is that the smoke is unburnt fuel... what color is it?

 

Thats what I was thinking, Maybe running rich?

 

its white smoke

 

Are you sure it isn't just light blue smoke? Is your car overheating at all?

Most of the oil drain related APS smoking problems I've seen (including my own) are on decel, not WOT. It could be something with your engine.

I'd try a compression test to help rule out the motor.

 

it could be light blue smoke. is that fuel burn off then? the car is not overheating. I mean it does smell like burning oil

 

Light blue would be oil, black would be fuel. Sounds like it could be an oil seal problem on one or both of the turbos....assuming the oil level is correct and the lines are trimmed.

Does it come out both sides of your dual exhaust?

 

^ im in the process of figuring that out now. I think since i drove the car a couple 100 miles with too much oil i could have hurt the seal in my passanger side turbo.

The engine has great power with only 15,000 miles on it so i highly doubt its the engine.

If it is a bad turbo seal, is there a APS dealer in the states that will swap the turbo out since its under warranty? or would just having the turbo rebuilt be a better option?

 

If it's a seal, I feel sorry for you. You'll have to pull the turbos and ship them to APS via air freight, all on your dime.

 

^ these turbos can not be rebuilt in the states?

 

I've heard conflicting reports on that, but I believe the answer is NO. Unless you want to pay out of pocket at least....

 

^ well whats cheaper? paying out of pocket for a turbo rebuild in the states or pay shipping and hope to get fresh turbos back? I hear of people sending their turbos to APS just to get them back not fixed.

 

That I couldn't tell you. It only cost me about me around $300-$400 to have them shipped both ways. Was your kit installed by an APS dealer?

 

no, it wasn't since there are no APS dealers in Colorado. But it was installed by a very reputable shop, Boulder Nissan.

 

APS is just going to tell you you're not covered since a non-dealer installed it.

 

so it looks like if its a bad seal, ill be having it rebuilt in the states. Any body know of good places?

All this really makes me wish i never installed a TT kit.......

 

PM tig, or do a search for his posts. I believe he had his APS single rebuilt here in the states.

 

First, it's $400 for the air freight to APS and back to the states. Next it was $800 to have Garrett in Australia to tear them down for inspection and replace with new cartridges and seals they wouldn't cover under warranty. That's what I got nailed for.
