Re: smoke from vent

could be a rad hose leak, or could be rocker gasket onto the exhaust.

Re: smoke from vent

I recently had a similar problem, the oil feed pipe had a slight drip when under boost and dropped a bit of oil onto the exhaust, once i came off boost and stopped i would get a puff of smoke from the drivers side vent, i replaced the seal on both sides of the feed pipe where it goes into the block and problem solved.
