Message Not much you can do about it... unless you want to mod the factory PCV set up.

When I used to run the autoX with some of the other fellas here, a few of us were puffing out smoke during our runs. Generally happens after a hard right turn (both PCVs are plumbed into the driver side exhaust valve cover).

If you have clean or fairly new PCVs, then some of the oil will make it into the intake plenum and get dumped out the tail pipe.

Wouldn't worry about it.

There is a mod you can do to eliminate this problem but it's a fairly big job that requires removal of the plenum. Try Searching for it, it's been documented here (sorry, too lazy to find it for you).
