13. Remove the engine oil dipstick (see "Engine Oil
Level").
14. Fill the sump with 2 qts. (1.9 L) of PS-4 Plus Synthetic

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
engine compression is rarely a factor in running condition
problems above idle speed.
A cylinder leakdown test is the best 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%)
