Blue smoke

[hick88]

Installed h&s tuner, cat and dpf delete, and afe intake about 4k ago. Yesterday while driving I noticed some blue smoke while accelerating followed by black smoke. Wasn't a lot of blue smoke, took off at the next light and it was all black smoke. Is the little bit of blue smoke somethin to be concerned about? Thanks.

well blue smoke is not normal but try returning your tuner back to stock. black smoke is typically excess fuel. is your turbo spooling up ok? 6L variable geometry turbos are notorious for sticking vanes, temporarily dumping too much fuel in.

The turbo spools up fine. The truck is currently in the shop, I started smelling exhaust in the cab. I also noticed oil coming out of an undercooler tube, the one coming off the turbo going into the cooler. Also when I returned it back to stock I noticed alight blue haze in the exhaust at idle when warming up. Any ideas?

Could be the oil feeding the turbo leaking past the seals.

Any word on your truck? I think my truck has the same problem.

The oil in the IC pipes can be fixed by doing the CCV mod.

They didn't find anything wrong with the truck. Yeah I've been considering the ccv mod

thx

hello anyone?

The CCV mod entails rerouting the crankcase vent so it doesn't feed back into the intake, and make everything oily.
