The
Oil Pressure Control Valves
control the oil
pressure of the engine. They open as soon as
the oil pressure reaches the maximum
permitted value.
The
Oil Return Baffles
prevent oil from flowing
back out of the cylinder head and the oil filter
housing into the oil pan when the engine is at a
standstill.
The
Bypass Valve
opens when the oil filter is
restricted, thus ensuring the oil supply to the
engine (the oil filter is bypassed; the oil supply is
unfiltered when the bypass valve is open).
