Burning engine oil + smoke from exhaust - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hi guys,

My S14 SR20VE conversion has been burning engine oil quite rapidly,it can drop from H to L in a few weeks, no signs of oil leaking or whatsoever. Engine has been rebuilt together with the VE head around this period last year with CP pistons and piston rings, supertech valvetrain set, new valve seals, tomei headgasket.

Some white smoke can be seen from exhaust from time to time, but not always. Once when I was decelerating to a stop at the traffic light and a cloud of smoke blew by. Not losing coolant as well.

My turbo is a stock S14 turbo. I am suspecting it might be the turbo as the smoke doesn't appear all the time which shouldn't be the case if it's the piston rings or valve seals?

Attached is a video of the exhaust smoke. Appreciate your inputs.
