valve cover to TB hose??

When I rebuilt my motor several years ago, I removed my smog equipment...smog pump, charcoal canister & all associated hoses & plumbing in the back of the heads, etc. I also run an offroad h-pipe. My question is...is it ok to have that hose that goes from the breather on the the passenger side valve to the throttle body, disconnected? I used to run a breather on the pass. side valve cover but during a speed run or even worse, a nitrous run...I would blow some oil out of the breather. This was due to the fact that I had to remove the baffle on the valve cover because of my 1.72 rockers...not from excessive blow-bye. So I don't want to hook that tube back up to the TB because when I'm at WOT I'll be spitting some oil back into the upper intake. I know that's fine and dandy for a stock, smog legal car...but I don't want oil in my upper intake. That's for air. So I currently run that hose w/ an extended line on it...from the breather down to where the charcoal canister used to be. I have it ziptied to some other crap down there and just have it exiting into the atmosphere. Is this ok? I'd imagine it would be just like running a breather on the valve cover with an open air filament. Is this freaking out my computer or creating a problem of any sort? I checked my vacuum a while back and it checked out fine.
