I am wanting to do away with the EGR value. Is there a different carb. plate available that does not have it. Or is the best way is to plug it off with a piece of metal? Will the engine perform better without it?
from what I understand is that the motor needs it to filter out the left over junk in the air that comes out of your crank case by filtering it there and then through the air cleaner then back through the motor and eventually out the tail pipe. (if I know what Im talking about ) I cant stand the look of it sticking out of my valve cover so at some point Im going to try to figure out something else. or I believe theres a blow off valve that can be installed somewhere to just throw that air out somewhere but I really have no definite answer here
Apparently you are confused, the PCV valve generally fits to the valve cover he's talking EGR, which is Exhaust Gas Recirculation(now that's one ugly valve, PCV looks like a prom queen in comparison)... In most carb application it a troublesome feature at best, but does have a value in that it reduces NOX emissions, still most of us are going to do away with the system... Usually that means blocking it off or installing a earlier factory or aftermarket intake that doesn't have the provisions... So if you have a emission inspection/test better keep it in place, otherwise I ain't telling if you delete it...
it would help if I read the question a little better the egr looks HORRIBLE youre right I was thinking of the pcv. was I right in my explanation on that part even though it wasnt what he asked?
No, even that was wrong. The PCV valve is a check valve, it allows the engine to draw in the crankcase gasses while preventing a massive loss of vacuum. It's not a filter.
well dang ok I knew it was something to do with the crank case gas/air being moved through the engine. see I can learn something every day :Handshake
Some PCV systems do have a filter, but it's more to catch oil vapor and direct it back to the crankcase vs actual filter... The EFI 5.0 has one (that mostly plugs up)mounted in the back of the intake under the PCV valve which is unnoticeable under the long runner intake... A similar valve mount could no doubt be adapted to most any carbed engine, in fact what Ford used on the mid '60 engines was similar to the later 5.0... Probably couldn't mount the 5.0 filter screen but it's more trouble than it's worth... Basically what I'm saying, on a mostly street engine PCV is a good feature, as it removes unburned vapors and moisture(to a point) from the crankcase ...
The filter under the intake was necessary to keep the PCV valve (or the road draft tube in the case of the 60's version) from sucking up the oil in the crankcase and causing excessive oil consumption. Really functioned more like a baffle than a filter.
So If I understand correctly,if my location has no emission check (which it does not) the car will run fine without it. Is there a Carb plate available to do away with the valve( is that better baddad) or do I have to have a different manifold?
The other option is to plug off the port that the valve bolts to right? Can I do away with the tube that goes from the manifold to the plate? And plug the hole in the plate.
You can plug the hole in the plate, but I would be concerned about a vacuum leak. Just have to seal it good. Yes, plug the port in the exhaust manifold....or just replace the entire exhaust manifold.
Yes your engine will run just fine without an EGR. Environmentalists won't like you but since you don't have emissions testing no one will know. Must not be in Calif. The Pcv is another issue. You either need that or a draft tube so the engine can breath. Ron
As I remember older Jeeps and some International Scouts used this same carb. They had the egr valve in a different place so you may be able to find the spacer plate at a junkyard. It will also have the nipple for the pcv valve in it. I don't remember the exact years so you'd have to do a little footwork! Late 60's to mid 70's Jeep and Scout!
