2x4s tunnel wedge and PCV

[Michael C Henry]

I have an chrome Motorcraft EC 2 breather cap for the right valve cover ,I have a squaty black Autolite EC 508 cap for the left valvecover. I have all the fittings and so on to create the PCV suction from the intake manifold plenum as speedd220mph did but a short squaty cap for the left fron valvecover opening. I bought a chrome Motorcraft EC 10 cap for the oil filler tube in the right front corner of the intake manifold. It is domed like the EC 2 but has a hose nipple on the side and is a push on. Problem the filler tube is too close to the aluminum valvecover. The filler tube appears to be a little short. That has been a problem in the past as it is only 4 inches tall from the intake manifold and is several inches shorter than the valvecover and a funnel is tipped. Question , Are the all baffeled filler tubes in the intake all soo short? Can a longer baffeled filler tube be bought ? Or do try to remove my tube and have an extension welded on to the bottom with an angle to kick the top of the tube out slightly from the aluminum valvecover th clear the new EC 10 push on cap.
I've ordered a plate to cover the breather opening in the rear of the manifold and I have a PCV plate adapter for that rear opening where I currently have a PSE breather stack. I bought an alluminum 1/2" T to connect two hoses from one valve cover and I had planned on the EC 10 on the filler tube for controlling the fresh air intake to the crankcase. I've been told that I need to limit the fresh air intakes and breathers to form a vacume on the crankcase with one PCV either from one valvecover or the rear intake position wher the breather stack is now. Descusion p[lease.
