thats a scary thought

anyone have a link to get a new seal?
i also got this reply on YSTC

My bet is that one of the seals is about to fail on the turbo itself, which is why it does it at full boost. Get a Innovate LC-1 w/ XD-16, engine management, and get a proper tune. It's also a ZPI kit, and not known for reliability. My money is on the seals failing.

yeah sorry but yeah.. i told you it was the seals going.. you can get your turbine rebuilt at your local transmission, radiator, tuning shops im sure but the price could be not worth it and you may want to invest in a new turbine.. but no oil in the intake and over flow tank makes me think the leak isnt bad at all so you dont have to worry about driving your car.. jsut stay out of boost. IF YOU CAN! haha

Under full boost most turbos will let out some smoke, in some cases normal,if the seals are bad enough oil will be found in charge pipes, etc. Most times runing rich will cuase smoke. Without knowing your afrs its kinda hard to tell. A compression check would be your first best step, and get a wideband. Also kinked oil lines, poor return line, can damage your seals. Exhaust Leaks can cuse you to run rich as well as vacum leaks.

You're stalling because of your BOV. We had the EXACT SAME PROBLEM on our ZPI Stage 1.5. When didn't have compressor surge or stalling when the kit was a stage 0, but after making it a 1.5, it was definitely a pain to drive.

You can try recirculating your HKS BOV, although you may need to get that fabricated for your ZPI setup, or you can get a different BOV. We recommend the Synapse BOV. We've used it on our ZPI kit with GREAT results.

We just shot a video comparing the HKS to the Synapse on a Dezod kit with the same results. No stalling period.

ok im starting to really get worried about this. i think i have an exhaust leak between the down pipe and spipe, but that wouldnt cause smoke? my wastegate is retarded and wont line up with the manifold properly, so i have to try and fix that. so theres a small leak there as well. i touched the inside of the canister for my exhaust, and there was this kinda gooey substance. kinda like oil, but stickier. theres also a burning smell. it doesnt smell like tires, or clutch. and i have no idea how oil or coolant smells when it burns. if i put a catch tank on to where i have the breather, would that help at all? would a CEL from the o2 sensor do this at all? if it is my turbo seal, should i just replace the spring and drop it to 4 psi? the burning smell and the smoke is really worrying me, to the point of i dont want my bro to even touch the car.

ANY help would be nice right now.

What color is the smoke again?

A leak in your DP/S-pipe won't hurt - it will actually give you more power unless the leak is before your O2 sensors.. If the leak is before your O2 sensors, the car can run wacky because the O2 is reading a much leaner condition.

The leak between the manifold and wastegate is NOT GOOD. This will slow the spool down, but even worse is that it makes the turbo work much hard to reach the spring limited boost level. Get this fixed ASAP.

To check to see if your turbo blew its seals, take off the intake pipe to see if oil is coming out of the housing. If there's oil, your seals are blown. Also this is a good time to check for shaft play. Make sure the wheel doesn't wiggle in/out. It may wiggle side to side a *little bit* but it can't wiggle enough to practically touch the compressor housing.

I'm not sure what the gooey substance is - you need to take pics of where that is. You mentioned its on the canister of your exhaust - is there a trail of that crap leading it there? It could just be something you ran into on the road.

Burning oil is a smell you can't mistaken. I'm sure you'll know it when you smell it. The smoke will look gray with a blue-ish hue. Burning coolant can smell sweet - smells like coolant pretty much and the smoke will be more white. It'll look like as if you had a lot of water in your exhaust and it's burning off. Completely black smoke is just too much fuel.

check your seals and replace them if needed, then save to get the car tuned. atleast with a greddy blue if you can't buy the ultimate or aem fic.

If it's white/blue then it's probably oil.

You may find that you're leaking oil out the turbo. But try and take the intake pipe off and check.

And if you can, try unbolting the DownPipe and check for oil in the back turbine side.

So you checked your intake to turbo and then exhaust side and show no oil leaks??

If you're just leaking from oil return, you shouldn't be blowing out bluish smoke.
