RE: K&N AirCharger CAI Install (w/pics & vid)
Hey Bill - hopefully you see this post and can reply even though its 6 months after your CAI install. I notice in the photos that you elected to replace the stock crankcase breather hose (the one with thegreen PCV valve) with a piece of rubber tubing, thereby eliminating the PCV. I know the PCV valve is one way, allowing gases to flow from the crankcase to the intake but not the other way. I was under the impression this is important, so that you don't get air flowing the wrong way if there is ever a higher air pressure in the intake vs. the crankcase. But in a normally aspirated engine that is probably not a big concern. At any rate, why do the replacement? What effect does it have on say the yearly emissions test (required where I live in PA)? I suppose I would just put the stock unit back on for the test then remove it again. Do you or anyone forsee any problems doing this? Thanks.
UPDATE: my bad, now that I have pulled that stock crankcase breather hose off and examined it, I can see that it is bi-directional. What I thought was a PCV valve (the little green valves in your photos) turns out not to be, its just a 90 degree elbow. The reason I asked this question was, after installing a BBK CAI system, the stock breather hose would no longer reach and BBK didn't provide a replacement in their kit. A quick trip to Pep Boys solved the problem.

(I get an e/m on all new posts [8D])
The black hose was part of the K&N kit. As far as what effects it has being bi-directional (ie. valveless), I don't know. However, my buddy with this same K&N CAI passed emmisions here in CA.
I've sinced swapped out the K&N in favor of the C&L Racer. This CAI also comes with an open hose.
