Blowing white smoke

Okay got a bit of a problem. I changed out my stock turbo with a 1.0 exhaust housing, ATS compressor housing, whicked wheel, and gutted the ebpv with the gillette high flow back plate. Okay today was the first day to drive the truck and its blowing mostly white with a tint of gray to black smoke. Its really bad from about 1500 to 1800 rpms. Goes away as soon as you let off the gas. I have checked for boost leaks by tightening all clamps again. My boost was 22-23 psi before now it pulls hard all the way to 26 so I didn't figure it was a boost leak. I thought white smoke was not enough air to fully combust the fuel is that correct? Should I go back to the stock wheel? Where should I start to correct this? Turbo has no end play at all. Thanks. Also this is on the tow safe setting or 70hp.

Just wondering, this might help a little...

When you (as in anyone) do the turbo mods that includes the housing, WW, and all that.. would it be worth getting a retune for these mods? I wouldn't know exactly what needs to be retuned. Perhaps that can play an issue of the overall better flowing mods put in the turbo compared to the complete combustion quality/power of the tunes you have for the "stock" turbo?

I wouldn't really think it'd matter too much.

Did you maybe have some old residual oil in your intercooler or IC pipes? Maybe just purging some old stuff?? Hope you get it figured out. My turbo just fried, and I had white/blue smoke on the throttle, and a big poof when I let off. Just my 2 cents

Thanks for the replys. Well I had another set of eyes besides mine, and we agree that its white bluish haze. Its pretty bad can't drive it during the day like this. I don't know will try to run a scan tomorrow for codes. Im pretty sure Im going to have to pull the turbo out, and inspect it. No endplay at all not sure what I could have done wrong putting it together. Oh well I will keep at it and if anyone else has anymore ideas post them up

Well this morning I could smell oil burning, so the only thing I can figure is the turbo is letting oil by the end seals? Im going to pull it back out, and have a look at it. I know I don't have any other option other then leaving it like it is, and make a mosquitoe killer out of it

Yep I sure did. I did the ccv mod at the same time and the way I set it up restricted the ccv too much and caused backpressure to feed through to my turbo and blow oil out the end seals. I have since pulled the hose off the doghouse and Im letting it vent to the atmosphere till I can try a larger hose and fittings to see if my filter system will work. Right now we have been getting pounded with a blizzard so I hope to get to it next week. Will keep ya all posted.

Off Topic a bit.. I've read the How-Tos on the CCV mod, however there is the idea of the filter or the route into a welded exhaust bung.

Any real issues just letting it vent out in the open like you have it setup now, behind the cab somewhere? Strong smell? How much oil residue is there in say a week?
