Why is my crankcase breather leaking engine oil?
From the top of the engine, everything looked OK. To get a look at the lower side of the crankcase breather, I jacked up the car, secured it, and went under to check for any anomalies. Low and behold, the leaking engine oil was coming from the lower part of the breather and was dripping on to the crankcase.
Can a bad crankcase vent filter cause an oil leak?
Oil leaks Oil leaks are one of the symptoms most commonly associated with a bad crankcase vent filter. The crankcase filter simply filters the blow by gases to make sure that they are clean before they are rerouted back into the vehicle’s intake manifold.
Is it possible to repair a crankcase breather?
Complete replacement is emphasized much more than repair. Such is the build and the price of them. You can perhaps dismantle and clean it but returning the parts in place without breaking them and not having leaks seems pretty unlikely.
Is the crankcase breather in the lower position?
A bit of a lower position but is accessible nevertheless. From the top of the engine, everything looked OK. To get a look at the lower side of the crankcase breather, I jacked up the car, secured it, and went under to check for any anomalies.
What causes Excessive crankcase pressure?
Excessive blow-by, a blown head gasket, a faulty breather valve, or a plugged breather hose can cause crankcase pressure to go beyond the working parameters of the breather valve, and cause crankcase pressure to exceed atmospheric pressure.
What is an engine crankcase breather element?
The crankcase breather filter element is part of the PCV or positive crankcase ventilation system. The crankcase filter captures oil and other bad elements and prevents them from going back into the engine. This item is commonly replaced whenever you do a tune-up on the car.
What is a crankcase filter?
A crankcase filter is the filter in the crankcase that ensures that the engine does not re-use oil-contaminated air back into the engine. Cars today are designed to return the crankcase fumes back into the engine. The crankcase filter, also referred to as the breather filter, essentially captures the oil residue in the air that passes the engine.
What is a PCV breather?
A PCV (positive crankcase ventilation) breather system is designed to regulate hazardous fumes from your vehicle. As your engine runs, combustion gases escape from the combustion chamber, finding their way into the crankcase of your engine. This unused combustion gas, also referred to as “blow-by,” can be a major cause of smog.

Why is Briggs and Stratton oil leaking from breather tube?
As the motor is used the high temperature in the crankcase causes this oil and gas mix to evaporate and those expanding gases create the pressure required to squeeze it out the breather tube.
What to do if oil comes out of breather tube?
If, the crankcase is not overfilled as 30yearTech mentions then take the breather cover off (I’ve never run one without it) and run the motor. Check and see if there is oil coming out at the bottom where the valve shaft goes into the crackcase. If oil is coming out liberally, there may be a worn valve retainer.
What are the symptoms of a crankcase breather problem?
SIMULTANEOUS LIGHTING UP OF THE EPC, TCS, AND CHECK ENGINE LIGHT Now this symptom is perhaps exclusive to Skoda Fabia or perhaps other Volkswagen group cars of the same generation. This symptom appeared at the final phase of the problem after the mentioned check engine light symptom.
