hi guys, iv got a 97 xj600n which is leaking a major amount of oil from the air box overflow. Seriously, when i stop and the engine is up to temp it pours out like a tap!!!!!! there is no smoke nd i am not over filling the sump? iv cleared the crankcase breather and theres no smoke. Any ideas.

What happens with the crank case vent dissconected from the airbox. With the engine running.

Yeh " and when oil cap filler is removed.[ ebgine running] is ther serious backpressure ?
