[DeTomaso] Oil Spray from valve cover breathers

[Sean Korb]

I want to warn you a little.  A PCV system under a stock motor with normal
build is fine.  It will take care of this no problem.  *If* you have a high
performance build with race clearances and high cylinder pressures, you
will need to find alternative and much more drastic methods of driving out
the gases.  Not just to contain the mess, but to prevent detonation at high
RPM if oil gets into the combustion chamber.  You can get a venturi port to
your exhaust system from each valve cover, or you can use an evacuation
pump.  Both are common on drag motors and somewhat less common for road
race motors.
