Here is Why Your 300zx Is Smoking on Right Hand Turns

If you find your 300zx is smoking when you take a right turn, particularly at high revs, here is why.

Basically, this issue is caused by the PCV valve on the left side of the motor failing. So what happens is the on right hand turns, the oil builds up on that side of the motor, and gets sucked in through the PCV hose into the intake, burns and comes out as smoke.

For the solution to this problem, watch my video: Installing a catch can on my Nissan 300zx.
