Icon5 EGR Valve Block Plate



Hello Everyone,

I was trying to figure out why the EGR valve is blocked but not the EGR PIPE?? If i block the EGR Valve shouldn't I just block the EGR PIPE as well????

I'm sure you will notice that exhaust gasses will fill up the engine bay if you block off the egr. Doesn't smell too pleasant.

I have never heard of exhaust gases filling up in the engine bay if you BLOCK the passage. If I don't block anything then yes exhaust fumes will enter the engine bay.

Re: EGR Valve Block Plate

Ooops! guess I didn't read it right.You must be in a state that doesn't require emission testing. Without my EGR here in Georgia, I failed the NOx part of the emissions miserably. Cylinders were running way too hot.

Re: EGR Valve Block Plate

Are you saying that you noticed the pipe wasn't blocked off? Yes you'd definitely smell exhaust gasses then.Did you look at someone else's car? If the pipe wasn't plugged , then you'd have raw exhaust fumes blowing everywhere in the engine bay.

Re: EGR Valve Block Plate

What I was trying to say about the EGR is that everyone talks about blocking off the valve and no one talks about blocking off the EGR pipe as well. Since I am located in the chicagoland area vehicles 1995 and below don't require emissions so I am going to remove it.

Cylinders were running way too hot.>>>>WHy were your cylinders running hot??

Re: EGR Valve Block Plate

Wow! You are lucky as hell. Here in Georgia, It has to be 25 years or older . Wish I was there. Actually, If you just unplug the vacuum line going to it then it would never open which means you don't even need to remove it or plug the pipe.

Re: EGR Valve Block Plate

Sorry for the late pic. I'm holding the vacuum hose that goes to the egr valve. If you disconnect it and plug it, then it'll never open. You'll always read too high NOx if you try to get emissions. Mine for some reason isn't getting vacuum. Replaced computers, MAP sensors and the vacuum solenoids. Still doesn't allow vacuum for some reason. One guy said it was the Absolute Pressure sensor. Not the MAP sensor. Can't locate one of those.
