Theres a reason why these arent so good for your engine, something to do with the Positive Crankcase Ventilation system, but I dont remember the specifics. Can someone remind me?

Also, would a clogged carbon canister (the big aparatus under the fuel filter) contribute to oil consumption?

 

Are breather filters really bad?
Yes they are. Read further for why.


The honda crankcase breather is a POSITIVE pressure ventilation system.The air from the intake blows into the valve cover. It is NOT a negative pressure ventilation system...it does NOT suck air from the valvecover to the intake.

Breathers remove the source of positive ventilation that repressurizes the POSTIVE CRANKCASE VENTILATION (PCV) valve.

There is less pressure in the crank when you add a breather at the valve cover. The consequence of this is you get more positive blow-by from the combustion chamber past the piston rings and into the crankcase. More blow-by means less cylinder pressure...less cylinder pressure means the burn is slower and less complete...the result is more emissions and less power.

If you want to do this right and remove oil vapor from the circulating crankcase before it goes into the intake valve then, get an oilcatch can and put a breather on the catch can. Then place the catch can in between the valve cover breather and the PCV valve.

Disconnecting the breather tube, which blows fresh intake air into the valve cover, and placing a breather on the valve cover just creates more blow-by and emissions. Eventually you have so much blow-by, you lose power.

Thanks to Team-Integra.net for this info :-)

Hope that helps you but i had to delete part of the article cause the pictures arent working

 

Werd. Thanks for the verification.

 

youre welcome :fawk:

 

Yes, yes, yes. :thumbup:

No, no, no.


Catch can goes here:

 

:fawk: post whore

 

haha no problem, i always like to give a helping hand to fellow members :-)

 

thanks to Team-Integra.net for this misinfo.. :chuckles:

 

:chuckles: Nice diagram of the right way though. :goodjob: lol

 

The PCV is only located on the valve cover on the non-VTEC motors.
