2016年2月17日 · The fix is either a dedicated breather kit, or barbs/banjo bolts, and rubber hoses, with a dribble can or breather under the bike. Figure 1. Stock air cleaner and breather hoses. Figure 2. Typical horseshoe breather kit. Step 1 – Remove air cleaner and filter. Remove the air cleaner cover and the air filter from the cleaner assembly.

2011年12月29日 · The reason is simple: having your crankcase venting to an intake area means the intake is pulling the gases out of the crankcase, so the crankcase will be below ambient air pressure. If you put a crankcase breather on, gases cannot exit your crankcase until the pressure inside builds ABOVE ambient.

2016年6月7日 · I've seen several setups on the 2.9 Whipple like the Whipple oil separator and a small breather filter on the bottom of the oil fill, Whipple oil separator and a hose going going from the bottom oil fill can to the cai tube, one catch can plumbed into the pcv line then into the top of the Whipple oil separator and even two catch cans and the whipple oil separator.

2016年2月2日 · Figure 2. Filter plate fasteners. Figure 3. Crankcase breather hoses. Step 3 – Remove filter housing (backing plate) Using a 7/16" socket and ratchet, remove the filter housing bolts to free the housing from the throttle body. Figure 4. Crankcase breather/filter housing bolts.

2020年10月26日 · Having the breather on the fresh air side can allow it to vent gasses and you'll notice some odor. I have the Mopar CAI (Shaker) and I've never noticed any stains on the filter, nor any oily residue on the hose. I have to remove the fresh air PCV supply hose to clean the filter (did the 40K cleaning of the filter, which is done every 20K).

2016年1月14日 · Here's an excerpt from page 8 of the attached document (from section ENSURING CRANKCASE GASSES EXIT THE SYSTEM AS CLEAN(ER) AIR): "Blow-by has been a problem for all these reasons since the dawn of the Stone Age. Well, at least since the dawn of the internal combustion engine.

2014年12月14日 · There is vacuum due to the PCV system. Intake manifold vacuum draws air/vapors from the crankcase through the PCV valve. That's the vacuum you feel. The hose that was left off is for filtered air to get into the crankcase. //

2009年12月10日 · The hose in both of your examples is indeed filtered. Look at it again, the hose in both cases, is in line after the air filter, meaning filtered air. In the case of the ram air, they wanted us to have it drawing air from the air box before the filter, so the hose would be able to suck in bugs and small birds.

2009年2月26日 · The base of the breather is CNC-machined from billet aluminum for precise fit, and the included silicone O-ring is specially designed to prevent oil seepage at the base of the breather. The filter base is microfinished for surface protection and good looks, and the removable filter element is a high-quality reusable unit from S & B Filters.

2009年4月11日 · Positive crankcase ventilation (PCV) is necessary to ensure there isn't a build-up of pressure in the crankcase. This would cause the crankcase to possibly crack under the pressure and create a huge mess of oil on the street. So the PCV system removes the pressure from the crankcase and reverts it back through the intake tract via crank case vents.
