write i have used a cossie breather and want to know if the breather has to be higher or lower the the rocker cover????????/ithink it may be just slightly higher but icould be wrong???anyone know??

thanks

 

Situating the breather as high as possible is best, but it doesn't really matter about it's position relative to the rocker cover - what is important is that the oil return pipe outlet back to the sump is higher than the oil level in the sump.
