1 - 10 LUBRICATION
OIL DILUTION
The lubricating oil in the crankcase is sometimes
thinned or diluted due to gasoline leaking by pistons and
rings and mixing with the oil. This leakage usually occurs
during the "warming-up" period when the fuel is not
thoroughly vaporized and burned.
The Hudson engines are equipped with automatic
devices that are designed to reduce oil thinning caused by
raw fuel dilution.
In order to assist the engine to warm up as quickly as
possible the water temperature is controlled by a thermostat
which prevents complete water circulation for cooling
until a predetermined temperature has been reached.
Another thermostat automatically controls the opening
of a valve mounted inside the exhaust manifold to
vary the amount of heat applied to the walls of the intake
manifold. This item combined with the previously mentioned
features greatly reduces the cold running periods.
Outlet:
The crankcase outlet ventilator is mounted at the rear
valve cover on both 6 and 8 cylinder engines.
In cases of excessive oil usage or leaks at rear main bearing,
check the outlet breather pipe. This pipe may be plugged
with dirt, and on the 8 cylinder engines, it may be restricting
at the valve cover baffle. DO NOT tighten the breather
outlet pipe attaching bolt more than 2 -3/4 to 3-1/4 torque
pounds.

As a further safeguard, the Hudson crankcase ventilating
system is utilized to expel from the crankcase any
ordinary collection of water or fuel vapors. In this system
the rotating crankshaft acts as a blower to force such
vapors from the case via the breather tubes on the valve
chamber cover.

Inlet:
CRANKCASE VENTILATOR
The crankcase ventilator inlet is part of the crankcase
oil filler cap assembly on the 6 cylinder engines. This filler
cap contains copper gauze which filters the air passing
into the crankcase.
The cap should be inspected every time oil is added
and should be thoroughly cleaned at least every 5,000
miles. Clean in gasoline and blow dry. Re-oil the filter
element gauze.
