i've been searching ahat the problem could be. people say either coolant is leaking into the housing or exess oil is getting dumped in and getting burnt up. but i thought that was blue smoke. also read it could burning carbon from the exhaust or in the engine also.

Hi, I have the same issue and was about to post my own but I see no reason to duplicate 
My car pours smoke after high revs, not sure on the exact shade but I would say it is whiter than blue, then again I am wearing a helmet with reduced vis and can only see in the mirror.
Mine occurs after heavy acceleration up one of our hill climbs, lay off the throttle for 3/4 seconds after crossing the line (applying brakes hard) and then it pours out with smoke, only for about 20 or 30 seconds though and a continual rev at about 3k clears it up.
I run pre mix though so my problem may not be quite alike?
I hazzarded a guess it is simply dumping fuel in when I lay off based on the revs still being high but clutched and braking. I see similar issues cruising or going down hills just allowing gravity to keep the momentum. I get flames and occasionally this causes the plugs to foul, taking a few good revs to clear.
Hope you don't mind me hopping on your thread

talking head
usually a symptom of oil control rings going bad,, and or turbo ( if applicable )
and usually hastened in demise by mods to the crankcase ventilation system
( dont block off the breathers and retain a vacuum or flow through system )

I've had those symptoms purely because of hooking up the crankcase breather system wrong. When the throttle was closed at high RPM, the vacuum in the manifold was strong enough to suck oil up through the breather and into the engine, where it was burned. It took a few seconds for the oil to travel that far, thus the delay.
When I hooked up the PCV system more correctly (combining some instructions here in the 2nd gen section with my own understanding of how the system is supposed to work), the problem completely went away.
