What may cause oil to spill out through the crankcase breather tube?
Pressure leakage from worn seals causes the oil to be forced down into the inlet passage and back through to the inlet filter. Typically you will get an excess of oil being blown out through the crankcase breather too as the cylinder head/rocker cover is pressurised blowing back down to the crankcase.
Why is oil coming out of my breather pipe?
Answer: There are two main reasons why an engine would pump oil out of the breather pipe: The engine is overfilled with oil. The engine blow-by is excessive. This hap- pens when the rings do not seal properly and the combustion pressure reaches the crankcase, forcing the oil out the breather pipe.

What does crankcase breather hose do?
The crankcase ventilation system works to relieve any pressure from the engine’s crankcase attributed to blow by gases by rerouting the gases back into the engine’s intake manifold to be consumed by the engine. This is necessary, as excessive crankcase pressures can cause oil leaks to form if allowed to build too high.
