MAINTENANCE
ENGINE GENERAL
ENGINE CYLINDER LEAKDOWN TEST
A cylinder leak-down test is the best indication of engine
condition. Follow tester manufacturer’s instructions to
perform a cylinder leak-down test. Never use high
pressure leakage testers as crankshaft seals may
dislodge and leak.
Cylinder Leakage Service Limit: 15%
If leakage exceeds service limit, inspect the engine for
the cause.
ENGINE MOUNTS
Inspect rubber engine mounts for cracks or damage.
Check engine fasteners and ensure they are tight.
