| Post subject: | filter for my breather |
Hi all, Just noticed recently when i had my air filter off recently that while the hose between the rocker cover and the air filter case was off that my revs were a lil higher and it seemed to run a lil smoother... The question i ask all you mini gurus is... do i have any options what i do with my rocker cover breather? i have seen a few of the guys on here use the small k&N filters on their crancase breathers.. would these be ok with the rocker cover breather? or no chnace of fitting? I also noticed that the rocker cover whole seems to suck when under load, should this be happening? and if not what is the probably cause... Any help would be tops Thanks Brad |

If the revs increase it would most likely be because you also have a PCV valve fitted also. First make sure you arent running a PCV system (funny disc thing with hose out the side, plumbed off the inlet manifold). The PCV system works by creating a 'vacuum' in the crankcase using vacuum supplied by the inlet manifold. This is supposed to reduce oil foaming, oil leaks, and excessive amounts of oil getting past the rings... and also reduce emissions. This could possibly be the reason behind why theres sucking that you describe. If you run a breather on a PCV (positive crankcase ventilation) system, it will defeat the purpose of the system in the first place, and also create a big manifold/vacuum leak, which will reduce the performance of the car and also possibly cause damage. On the other hand if you do not have the PCV system and only a blowby hose to the air filter case, you can remove the hose and plug it at the air filter case, and fit a breather to the rocker cover. K&N make breathers and so do redline. There are some other cheap crappy types that are more for bling than anything... I have a Redline filter i got from one of my local auto parts stores. The only problem i find is when running the heater while stationary at the lights, it draws in blowby fumes which are pretty awful smelling. |
