So i have smoke coming from my exhaust, only after it idles for a bit while on and i press on the gas. Doesn't smoke WHILE it's idling, only after it idles for a bit and i drive off or gas it while it's standing. I checked the intake going into the turbo, no oil puddling on/near the turbo inlet. But there is oil coating the intake pipe after the intercooler. Could this be the problem? How would i fix this?

Will changing either require pulling the head off?

Yes it dose.but if it is valve seals no, valve cover needs to be removed and then you can replace the seals, usually that should fix the problem. Also I did replace the turbo oil line with Detroit tune oil line.
best thing you can do.
I am sure there are other members with lot more knowledge that can chime in, this is just my opinion.i had to have mine done.
