I just finished installing a K&N cone filter on my 94' P.U. 2.4 4x4
I'm trying the setup that I saw one of the members use in which I swaped the location of the battery & the air cleaner assy. It's now a nice short path to the TBI and it looks clean to.
My ? is the tube that went from the PAIR valve to the resonator then to the air box. Can I just block it off at its port with a vaccum cap or will that cause problems with other emission parts. I was just going to leave it alone but if I do that upon deceleration it make a nasty noise

Any advice would be great Thanks in advance

I dont think you can cap it off. You have to put a filter on it. A crankcase filter is what is recomended but I haven't been able to find the right size for mine, and I decided to go a different way on my air intake even though I have a cone filter sitting in my garage.

ps. TBI = Throttle Body Injection
TB= Throttle Body

i had a k&n filter on my 22re and use a valve cover filter for what ur talking about i reused some of the old vaccum line and just used that filter

I've been told by a couple mechanics that you need the slight vaccuum produced by the intake for your BOV to work properly. I talked to one guy who had built a serious 22re (over 200hp) and he replaced the hose with a filter. Then next day he blew out some gaskets from the over pressure in the crank case. Just put in an inline filter if you can and maintain the stock configuration the engine is designed for it.

This is the motor I just put in my 89 and was told it is a 90, but I don't think it is. The resonator is totally bypassed by having the hose go up to the throttle body instead of going to a resonator and to the air box.....anyone have any idea what year motor this really is? Maybe you can do the same thing to yours to get rid of the resonator setup?

I guess I need to do something different. Now I got a shop rag doubled a couple times and a hose clamp holding it on.?

I tried running a 5/8 hose with a crankcase breather on it (with out the resonator instaled) and it makes a very loud rumbleing noise on deceleration. Is the lack of the resonator my noise problem. Other wise the truck runs and drives great with no check engine lights. My only other concern is that the hose went from the PAIR vale into the resonator then into the stock air box. So now there is no flow from the hose into the air box (Just before the MAF con.) Will this cause a problem with emissions.

Thanks everybody for all your help

If we are talking about the hose that comes from your blow off valve in the valve cover then it needs to go from the BOV to the intake tube at some point. If you want to keep the crankcase gases out of the intake (not a bad idea) then put in an inline filter in. I'll say it again the BOV needs the slight vaccum produced in your intake tube. If your talking about somthing else the ignore me hehe.

I'm still getting used to all the systems on my truck. So I'm not sure what BOV stands for but it does not sound like we are talking about the same part. My intake set up does not look like (Yotakimmer) set up. I dont have that vacuum port on the T.B. also that hose looks to be 1/2 were my is 5/8. From what I see in the manual 92'-95' 22 RE (Fed/Can) are calling it A PAIR valve. 91'-95' (Cal) call it a AS REED valve.

Thanks for all the info

I still have not been able to find out the exact function of the AS REED valve on my 94' Toyota pu 22re. But I have found out that it does not afect emissions. I removed the resonator,the hose, & then capped off the port. I got my inspection sticker with no problems. ( In MA, were they put it on a chassis dyno and simulate the truck under load it passed no problem)

Just thought if anybody else was going to swap the intake & the battery and was unsure of what to do with AS REED valve you shouldn't have a problem bypassing it.

AS REED Valve uses exhaust pulse to suck fresh air into the exhaust. The fresh air source is behind the air filter in that convoluted Intake silencer you just threw away. The fresh air is used to provide the catalytic converter a source of oxygen to complete the combustion processes and reduce emissions of carbon monoxide.

Most people with non-stock intakes hook a crankcase breather filter up to the hoses. It is louder, but it does seem to work.

I can buy the fact that a little vacuum on the AS reed Vavle helps the reed valve snap shut.

This is my last post on this subjuct. And I would just like to say TANK YOU very much Ieiniesred for that explanation. Even though I passed the emission test perfectly, and the engine runs great at all RPM's. I don't want to set up problems down the road.

Thank You: Everybody for all your hjelp
