Re: Need input on noise - 2009 2.5 liters
I'd bring it to the dealers attention, if anything at least it'll be documented should any concerns arise later on.
Oil should drain back down into the crankcase within an hour after shutdown. Some might say it only takes half an hour. Right when you turn the vehicle off, the majority of the oil goes back into the crankcase, the rest slowly drips down (maybe less than half a quart).
Perhaps there's a gasket leak, as the gasket warms up with the engine, the leak will subside. Valvetrain noise is not uncommon on startup, such like a fast tick sound for a few seconds. To have a 'pfft' sounds, it might be intake or emissions related. Perhaps a bad EGR valve or a hole in the intake. The dealer should be able to put one of those electronic stethoscopes in and around the engine to narrow down the problem. The only downside is that you may have to leave the vehicle there for a couple days so it can be 'off' for that 15 hour period.
