NEW ENGINE BREAK-IN AND OPERATION
\ The engine underwent a run-in at the factory and is ready for the full
range of use. It is. however, suggested that cruising be accomplished at
75% power until a total of 25 hours has accumulated or oil consumption has
stabilized. This will ensure proper seating of the rings.
ENGINE OIL SYSTEM
Oil for engine lubrication, propeller governor operation, and turbo-
charger bearing lubrication is supplied from a sump on the bottom of the
engine. The capacity of the sump is 8 quarts (one additional quart is
contained in the engine oil filter). 0111S drawn from the sump through a
filter screen on the end of a pickup tube to the engine-driven oil pump. Oil
from the pump passes through an oil pressure screen, full-flow oil filter,
turbocharger bearings. a pressure relief valve at the rear of the right oil
gallery, and a thermostatically controlled remote oil cooler. Oil from the
remote oil cooler is then circulated to the left gallery and propeller
governor. The engine parts are then lubricated by oil from the galleries.
After lubricating the engine. the oil returns to the sump by gravity; oil
from the turbocharger bearings is returned to the sump by a scavenger
pump. The filter adapter in the full-flow oil filter is equipped with a bypass
valve which will cause lubricating oil to bypass the filter in the event the
filter becomes plugged, or the oil temperature is extremely cold.
An oil dipstick is located at the rear of the engine on the right side, and
an oil filler tube is on top of the crankcase near the front of the engine. The
dipstick and oil filler are accessible through doors on the engine cowling.

(dipstick indication only). For engine oil grade and specifications, refer to
Section 8 of this handbook.
An oil quick-drain valve is installed on the bottom of the oil sump, to
provide a quick, clean method of draining the engine oil. To drain the oil,
slip a hose over the end of the valve and push upward on the end of the valve
until it snaps into the open position. Spring clips will hold the valve open.
After draining. use a suitable tool to snap the valve into the extended
(closed) position and remove the drain hose.
IGNITION-STARTER SYSTEM
Engine ignition is provided by two engine-driven magnetos encased in
a single drive housing, and two spark plugs in each cylinder. The right
magneto fires the lower right and upper left spark plugs, and the left
magneto fires the lower left and upper right spark plugs. Normal opera-
