Quick Q. on smoking motor

[ajinvista]

Put my engine back together and broke it in, have about two hundred miles on it.
Not a bit of smoke for about 4 days, turned up boost a little (MBC), hit about 17 lbs, backed off to about 12 lbs. Drove around for a while then it started running like crap and would die.
Noticed that the motor smokes horribly on left turns only.
I can only guess is valve stem seals, only one plug was oily, the one on the far pass. side
#4. If it is how do I avoid this problem in the future. The motor has been built to take some boost and rpm's.
This project is finally done after years of sitting and it's running excellent and I want to get to the track. Any input would be great.

Please kill this thread, it's got to be rings. Thanks
