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: 20%

If leakage exceeds service limit, inspect the engine

for the cause.

performed on a cold engine, at room temperature.
