if you pull out the dipstick with the car running your creating a vacuum leak.. if you have an intake you will hear it sucking in air also when its removed.. I have never heard of pulling the dipstick to check the PCV.. I pretty sure you have to disconnect it and see if you can blow through one end.
well if that's the case, where can I disconnect the PCV and do this check? and if I can blow through one end, does that mean everything is okay? or is something wrong?
I'm just concerned because I swear the car isn't feeling as quick as it did before its first oil change. I'm fairly certain it's not the DV because my car is a 2008 and I think it has the 'G' revision (the one right before the latest 'D' revision) and plus I think it would throw a CEL pretty easily if the DV was toast and that it would also feel SIGNIFICANTLY slower if the DV were dead.
I've also heard that I should be hearing some kind of howling at low revs or something if the PCV is dead, but I'm not entirely sure what this howling is supposed to sound like. when I'm accelerating slowly at low speeds, I do hear a kind of hollow wind sound from the front of the car as well as a kind of low-pitch whistling almost from the engine bay (which I guess could almost be considered a howling), is that the howling that is being described if the PCV is gone?
let's just say, it's driving me nuts. either something is actually wrong with the car since its first oil change, or I just suddenly got used to how fast the thing feels. but I mean, before its first oil change it consumed NO oil at all, but now I've added almost a quart of oil in the last 2000 miles (give or take 1000) or so (which some have said is pretty much normal).
