Vent it back to the valve cover.
Um, no. The air switching valve and reed valves in the valve cover offer a way to vent the PCV back out. So what Dricked is recommending is a very easy and valid way of accomplishing what you're after. Cap the airbox line, and route the PCV to the air switching valve that normally comes from the airbox. Done.Sorry..I don't understand the theory on this.
That would be the same as capping it off.
The pressure needs to vent or there will be other issues.
Put the stock caps on that have the vent, connect them and put a "T" hose fitting in between and run the crank vent to the 3rd port on the "T".Yes that would be easy.
Block off plates installed!
The pair valve system is removed. The oil vapor is put back into the motor. If you get oil from your head into your exhaust system you've got some serious issues.Nice..
My only issue with this method is the supply of oil filled air into the pair valve system and the possibility of contamination of sensors down stream in the exhaust...other than that looks like a good method.
I'll have to give it a little more thought on how to best tackle this crank vent line..for now I have it routed the same as you, up the right side, but mine is going out front to a small disposable container beside the forks.
And yes the air box is capped off
Thx for the insight..
Thanks, I was too lazy to find the picTaken from dricked's build thread, the photo shows how it's supposed to look on a Gen4. I don't imagine Gen5 is much different. I did this mod recently too but ran the hose around the other side of the motor without the 90 degree elbows so you have some options there. Be sure to plug the airbox. I bought the hose at a local auto store (winchester auto). I believe it was listed as a heater hose or something like that and they also had the T coupler.
No, it puts the air into the top of the head where your cams are. Would you like more pics? I have the valve cover off to set the valve clearances.This setup pictured above pressure feeds oil filled (ccv) air into the exhaust.
Agreed...if you if you get oil from your head into your exhaust you either have a cracked head or blown head gasket.
You can tune just fine.you simply connect the hoses, I do not think you need to take out the reed valves.
this mood is supposed to give some hp, since the exhaust gases are sucking air out of the crankcase.
problem with this mood is that you cannot tune with this mood.
Yep ok. So then what sensors in your exhaust are being affected by this new setup if you already have a way for oil to make its way into your exhaust system?Those ports/covers/block off plates we are talking about, feed air from the air box, or in your case from the ccv, into the valve cover, downward into the exhaust ports. These passages are from the valve cover to exhaust ports cast into the head.
This type of system was designed way back when they first started with emission standards.
Sorry for dating myself..
