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.
