Whirring air sound, possibly related to enlargement of pcv hole in intake?

[QUOTE="mirageman, post: 27294, member: 6542"] I took off the intake again to check that pcv hole and indeed it is larger than the other I saw in another post. The pic with the green gasket around the pcv hole is mine currently. It is much bigger than the blocked hole in the other pic from another post on this site.... I thought if I did drill it, it was a year ago and just a bit. I think I went too far. I also took a video showing the whirring noise and how it stops with pulling out the dipstick, but it seems like this site will not accept my format. I think this bigger hole might be the problem, sucks too much, and perhaps not enough crankcase vapors to keep up. This manifested after replacing my rusty, leaky oil dipstick tube. A new intake manifold is not bad at $125 at autozone and you can go the 20% off route with free shipping, but I think I'll try to take a soldering iron to that hole there and try to make it a virgin again before spending that money. There are videos of very similar sounds but different cars with actual pcv systems. This one comes close: [MEDIA=youtube]4G5VTC17SIw[/MEDIA] [/QUOTE]
