Remove my hoses and/or vacuum lines?
I read an article, written by Mark, called "Performance mods for the 22RE", in the tech write-up section. Nice tips Mark. I don't know who Mark is, or I would ask him.
My questions have to do with this picture from the article: https://www.yotatech.com/~corey/tech...ne/headers.jpg As you can see, the hoses that run from the PCV valve to the valve cover, and another from the valve cover to the Idle Air Control Valve have been removed and replaced with breather elements. Is there any negative impact from doing this? Also, The cluster of sensors and vacuum lines that sits on a metal plate atop the valve cover have been taken off. Can anyone shed some light on what vacuum lines and/or sensors, etc. can/can't be disconnected safely? Mark? The less things I can have under my hood, the better. Thanks, |
Bump, I would also like to know this.

the front breather goes to the air cleaner assembly, mine is taken off and has that filter... it wont pass visual on emissions becasue of that... the otehr where the pcv goes.. and i disconnected mine and my truck would run without it....

Any peformance gains from this, I dont have inspections :) so im not to worried about that.

Don't know if yours is the same as mine, but the front breather on mine goes to the throttle body as seen in this picture:

That is your A/C idle up VSV. Won't hurt anything, but your idle speed will not uincrease with the A/C running. You can also remove and plug the two lines to the p/s pump. Same deal, no idle up when you try to steer, but no big deal. Then pull the rear-most VSV (green/blue in the picture below - operates the fuel pressure regulator) and just run a line from the intake to the FPR directly:
