I know the early EVO’s were a crank case breather system and HD changed it at some point to head breather system but I don’t know the year they did this. I sure someone with the knowledge will chide in shortly. Umbrella vavle’s were used with the head breathers only that I know of. Does your heads have a bolt on the side just above the air cleaner?

Good machined cylinder bores with known working umbrella valves, you can put those hoses in your boots. Run my hoses to the ground and may of gotten a drop hit the ground after 7 hard years with the 89", the current big cube high compression engine doesn't even have hoses off the head turn downs and not a drop of oil on the engine in 4 years, give credit to the the guy that does my cylinder boring.
If you are spewing oil out the breather system with a top breather, repair the base problem and not mask it, the money saved from not buying gizmo's can replace hardened umbrella valves plus get the hoses out of the back of the air filter plate, eating your own chit is for chickens, not engines.
The OP's breather system is right, may offend a few tree huggers but a Harley is built to De-EPA and make it better.
