Another PCV question

Yesterday I replaced the old dried out PCV and breather grommets on my 350. Now when I drive it there is a whistle comming from the PCV side. Before I replaced them it was blowing alot of oil out of both sides but the new grommets have fixed that. Could my PCV valve be stuck? If not should I be worried about it? Thanks.

Sounds like something is not completely sealed up. It may be a vacuum leak you're hearing. How's your idle? You can spray some carb cleaner around the area you're working on and see if the idle changes to find the leak.
Good luck.

I'd start with a new valve, they are cheap even by my standards
