SECTION 3. BREATHER ASSEMBLIES
The Breather is a sealed assembly. If it is defective,
replace the entire assembly. The rubber tube on the
outside is not part of the assembly.
Install the breather with the drain holes toward the
base of the engine. Always use a new gasket. The
retaining screws must be tight.
If oil is being pumped out the breather:
1. Check for excess speed.
2. Operating at excessive angles.
3. Loose oil filler cap.
4. Worn rings.
5. Excess blow-by.
6. Breather body installed up-side down.
7. Overfilled with oil.
