383 Stroker Oil Coming out of Valve breather

Hey guys, I recently bout a 13’6” Alumitech with a 383 Stroker on it. Boat runs great and has a ton of power. When I run it real hard I got oil coming out of the driver side valve breather. Anyone got any advice on how to fix this. Other side has a hose connected to the motor. I’m new to air boating and relatively new to motors. Any advice or assistance is greatly appreciated!
 
A bit more information would help diagnose the issue.
So assuming the right valve cover has an open or screened breather, the left has a hose, where does this hose go?
Pictures speak more than words.
 
Turn the solid side towards the front of the boat,,, this stopped it for me

John, thanks for the quick reply, see the attached photos. Breathers look like they’ve been there for some time. Thinking about putting a new pair on, lmk your thoughts.

Looks like a PCV setup, there would be no vacuum to support this at a wide open throttle run, blow-by would be exiting the open breather, plug the vacuum port at carb, omit both rocker cover set up, go with what Andy suggested on both sides!

I’ll give this a go and let you know!! Thank you so much for the help!
 
If you consider swapping valve covers check out the ones the circle track guys run. They have tall tubes 2 or 3 inches that your breathers sit on
