Breather Filters? Crankcase Breathers?

[Samurai_Blue]

During normal operation, a small amount of unburned fuel and exhaust gases escape around the piston rings and enter the crankcase, referred to as "blow-by". [6] If these gases remained in the crankcase and condensed, the oil would become more diluted over time, decreasing its ability to lubricate. Condensed water would also cause parts of the engine to rust. [7] To counter this, a crankcase ventilation system exists to draw fresh air in from the air filter and expel the gases out the PCV valve into the intake manifold. In a non-turbo engine, the intake manifold is at a lower pressure than the crankcase, providing the suction to keep the ventilation system going. A turbo engine usually has a check valve somewhere in the tubing to avoid pressurizing the crankcase when the turbo produces boost.

If an engine is damaged or enters old age, gaps can form between the cylinder walls and pistons, resulting in larger amounts of blow-by than the crankcase ventilation system can handle. The gaps cause power loss, and ultimately mean that the engine needs to be rebuilt or replaced. [6] Symptoms of excessive blow-by include oil being pushed up into the air filter, out the dipstick[8], or out the PCV valve.

purpose of the valve cover filter....imo i think leaving the pvc tube is better than the filter

oh and that was from the first hit on google btw

lol who would of thought all that info could be found online?

:what: idk google saves lives and time

I don't see why the filter is bad?

I don't see why the filter is bad?

read what i posted and think about it.

 

[Ballerin1]

So basically its just a filter for itself, I still don't see why its bad. I've read it twice. Am I a :retard:?

 

[hamfacekilla]

if the blow-by gets gunked up in the filter over time, it will be sucked back in eventually

 

[Ballerin1]

So can't u just clean/replace the filter?

 

[hamfacekilla]

^absolutely

 

[Ballerin1]

So when its actually clean is it better?

heres how i see it.

Durring blow by the motor sucks in air through the air intake. If you have a breather filter on where does it suck air from? the air flow from the intake helps move air into that tube allowing the pvc valve to be utilized in a more efficient way

this is true, the valve cover has its own suction, but it makes it easier on the motor when the air is already flowing through the tube

From the filter. Doesn't it? ^^
