Do you mean blowby?

Is the engine warm or cold when this is being experienced? You will have some blowby, more when then engine is cold of course. But when your at idle it shouldn't really be noticeable. If when you unscrew the oil fill cap and it pops off and there is a continuiouis stream of blowby you have a problem. If it pops off and then clears and I would look into the crankcase breathing system. Hope this helps. I'd suggest doing a compression test.
