CYLINDER HEAD

See General Warning on page 1-1.

GENERAL INFORMATION

Test cylinder compression using a standard compression tester. Low compression would normally indicate a problem
in the cylinder assembly such as defective rings, gaskets, etc. At a cranking speed of 550-600 RPM, the compression
should be 156-185 psi. See Engines and Transaxles Manual for inspection and repair.

BREATHER VALVE (REED VALVE)

General Information
The function of the breather is to create a vacuum in the crankcase which prevents oil from being forced out of the
engine through the piston rings, oil seals or gaskets. The breather has a reed valve which limits the direction of air flow
caused by the piston moving up and down. Air can flow out of the crankcase, but the one-way reed valve blocks return
flow and therefore maintains a vacuum in the crankcase.
Oil laden air in the crankcase passes through the reed valve and expands into the rocker chamber. In the rocker
chamber most oil separates from the air and drains back to the crankcase. The air passes through a tube and vents to
the intake manifold. See Engines and Transaxles Manual for inspection and repair.

CRANKCASE

See General Warning on page 1-1.
