Custom breather rocker cover.  This rocker cover is designed for high performance road and competition MG Midget, Sprites, Morris Minors etc.
 
The gerneral rule of thumb for the A series is 3/4" of breather 100bhp. Higher performance engines often have higher crank case pressures. Restricting the breather will put extra pressure on seals and gaskets.
 
This Rocker cover is designed to feed the timing cover breather up into the cover and then out to a catch tank. A sealed breather system.
We are currently having our own catch tanks manufactured for this application. In the meantime you can purchase the Rocker Cover, the silicone pipe, clips from our store.

16mm Inlet from Timing Cover
