Crankcase Breather
1. Check crankcase breather as follows:
A. Gently blow air into breather hose (
A
, Figure 168) to
verify that there is no air flow through valve.
B. Apply vacuum or draw air out through breather hose
to verify that air flows freely through valve.
C. If air flow has no resistance when blowing or is
restricted under vacuum, the breather is faulty.
