13. Remove the engine oil dipstick (see “Engine Oil
Level”).
14. Fill the sump with 2 qts. (1.9 L) of PS-4 Plus Sy
nthetic
Engine Oil (2876244).
15. Verify the transmission is still pos
itioned in PARK (P).
16. Start the engine and let it idle for one to two minutes.
17. Stop the engine and inspect for leaks.

n
ecessary to bring the level to the upper mark on the
dipstick.

Engine Breather Hose Inspection
The engine is equipped with a breather hose. Inspect the
breather hose for possible kinks or wear. The hose is
formed for a proper fit. Follow the breather hose from the
side of the airbox to the engine valve cover.
NOTE: Make sure line is not kinked or pinched.
Engine and Transmission Mounts
Periodically inspect engine and transmission mounts for
cracks or damage.
Refer to Chapter 3 “Engine Assembly and Installation” for
m
ounting fastener torque values.
Compression and Leakdown Test
NOTE: This engine does NOT have decompression
components. Compression readings will vary in
proportion to cranking speed during the test.
A smooth idle generally indicates good compression. Low
eng
ine compression is rarely a factor in running condition
problems above idle speed.
A cylinder leakdown test is the be
st indication of engine
condition. Follow manufacturer's instructions to perform a
cylinder leakage test (never use high pressure leakage
testers, as crankshaft seals may dislodge and leak).
Cylinder Compression:
165-185 PSI
Cylinder Leakdown
Service Limit: 15%
(Inspect for cause if test exceeds 15%)
