V70 White/Blue Smoke

Recently noticed white/blue smoke from my V70 petrol on hard acceleration though not all the time, checked coolant, not using any, checked oil, not using any. If i rev the engine in neutral there is a very small amount of smoke as it hits the limiter but nothing that would seem unusual. Put some injector cleaner in 2 weeks ago but has had no effect. I have looked through various posts but all smoke issues seem to be related to oil usage or coolant usage - any ideas

Turbo? Non-turbo?

Pull out the oil stick at idle with the engine warmed up - does smoke puff out the opening? A clogged PCV system can cause smoke out the exhaust.

The only other suspect on a non-turbo would be worn valve stem seals.

Finally got round to checking, yes there is smoke whne the engine is revved, now to trawl the forums on PCV - thanks
