| + | ====== Symptoms of Breather problems ====== | ||
| + | |||
| + | The most noticeable signs of breather valve problems are weeping gaskets or oil excessively leaking out the breather or puking oil out of it. \\ | ||
| + | When the umbrella(s) gets hard, it doesn't flex well to allow the engine to breath out on exhale. \\ | ||
| + | Then the trapped in air is compounded on the next stroke. The excess air contributes to more vacuum created and implodes the gaskets. \\ | ||
| + | Or it contributes to too high of oil density and slings excess oil out. \\ | ||
| + | Other factors are involved so results will vary. \\ | ||
