How easy it is to remove the rocker one way breather valve (the plastic right angled one which goes to the inlet chamber from the cam cover). Can i do it purely by pulling it out of the covers or do i have to get at it from the inside?
I dont *think* its nackered, its just that i want to eliminate absolutely everything that could contribute to my smoking problem before i put the turbos back on, and the valve does look a bit mucky inside.
