[Fot] Valve cover breather

[Kas Kastner]

The oil pan pressure goes into the head and valve cover, and chances are 
with no way out, will liberate itself by blowing out under the gasket and 
around the oil filler cap. Even with the 1" minimum breather on the block, 
you still need the one on the valve cover, not just a little 1/2" hose 
either.
