"okay just came back from the dealer he said the aos is bad and the oil filler tube is has a leak"

Is there a way to diagnose an oil filter tube vacuum leak?. I think I have eithor have a vacuum leak somewhere or a bad MAF. Getting gurggling and popping on cold startup and I think my mpg may be going down, though its hard to tell as I have been driving with a heavy foot these days.

replaced the AOS and upon re-firing the smoke machine re emerged, it idled rather well and so I gave the throttle a few light taps and eventually the smoke died out. I checked the levels and they are all fine the only issue is there is a slight hiss sound, much like a vac leak. When I remove the oil filler cap the motor starts idling funny, rises falls and sputters very sporadically. Started it up again this morning, small cloud of smoke and stopped almost instantly. Figure its remaining oil in the intake, working its way down to the motor. Should there be an issue when I remove the oil fill cap while running.

Cool, not for you, but for me. That is what mine is doing at idle which makes me think I have a vacuum leak not the MAF. I will order in and replace the oil filler tube, get a new oil cap and continue to look for vacuum leaks, any ideas for other leak points would be appreciated.

Simple test, unplug your MAF. If that improves things, swap it out for a new one.
