It only does it at cruising speed under no load, or at an idle. Acceleration, deceleration....no issues. Runs like a champ, no codes, no issues. I installed one of the RB PCV valves thinking that might help...nope. New flapper valve on the PCV system....no change.
Could it just be oil building up in the PCV system, and then randomly dumping it into the intake? Should my next step be to install a catch can?
I'm pretty sure it's not turbo seals.......it's too random.
Ideas?

It is pretty hard to imagine how a random dumping of oil from the PCV system would occur.
Are you 1000% sure you're smelling oil when this happens?
And that the smoke is coming out of the tailpipe?
Is the smoke thin, wispy and rapidly dispersed or is it heavy and hangs around for a bit?
Have you ever captured a log when this smoking was occuring?
