Blowby Limits
The
following
table
gives the values of blow-by
that
are normal for the Dodge 5.9 Liter Diesel engines. These blow-by
values
have been calculated on amount of displacement of the engine, volumetric efficiency, cylinder
pressure
and
turbo contribution.
Note:
The blow-by
values
are for 100 percent load at the given speed.
Blowby Measurement
Blowby is generally recorded in Liters/Minute, but a water manometer may be used to measure blowby from the
breather
tube.
Pressure
readings
in
inches
of water are measured using a 5.613 mm [0.221 inch] diameter orifice.
Use a service tool with 5.613mm [.221 in.] orifice
built
in.
