Yeah, I think all my 4V heads have pushed a decent amount of oil out of the breather. It's a stroked motor so probably running a bit higher compression than stock. I bought one that screwed into the dipstick area, but never drove with it in because it just seemed like it pushed oil out of the crankcase and away from things that needed it. I have a hose with a Uni breather filter run up under that rack from the valve cover, but after a decent run it's dripping oil all over the place.
