I searched and couldn't find a definite answer.

When I first start my prelude up in the morning it shoots a huge black cloud of smoke out. After it runs for ~10 seconds is fine, it doesn't even dump smoke in VTEC. It wont do this again unless its sitting for a while. Could this be oil slowly seeping into the cylinders? Its black not blue though, Ill try and get a video. Valve seals?

Maybe injectors that are slightly gummy and then free up after a bunch of pulses.
Thats what I was starting to think. Maybe run some marvel mystery oil through there.
