Yeah, I wouldn't think it would have any difference on your engine at all. The only thing it is doing is releiving crank case pressure. And there are many people that totally delete the PVC system and just put in a breather. Does the same thing. Just lets pressure out of your crankcase so you don't blow seals. You don't really want you engine all sealed up tight. It needs to breathe.
And like someone else said, the dipstick doesn't really seal all that well anyway. It is more just to keep dirt out of the engine. So that is what I would really be worried about. Make sure nothing can get down in your crankcase and you should be fine.
