noise coming fron egr valve

[gudz519]

hi everyone when i start my car i think it is my egr valve in front of my vavle cover on the right side it makes a deep gargling sound anyone else expierence this? or is it normal thank you

Are you sure? I've never heard anything come from that thing

 

[gudz519]

yup the black circular thing right in the front almost positive

 

[head_trauma911]

Yeah ok, thats what i thought you were talking about, if it were me i'd just ###### replace that thing,

 

[gudz519]

what does that thing do and what is it?

i had to replace my egr valve on mine so it would pass emissions and it is not needed for the car to run but it basically helps your car completely burn the fuel by running it through the combustion process again and it results in a cooler, more complete burn of the fuel which decreases you cars noxious emissions and keeps harmful gases in so they dont pollute the earth. and for the sound you heard. i have no idea, ive never heard anything

 

[gudz519]

thx alot for the reply

Just block it off. EGR isn't needed, robs performance.

Ideally, fuel should be completely burned during the combustion process, though this never actually happens. (HC emissions)

The EGR recirculates exhaust gas (which contains very little oxygen or fuel) to reduce combustion chamber temperatures for the purpose of reducing the formation of NOx emissions. (Nitrides of Oxygen) A small MPG improvement can be seen with a functional EGR system while cruising due to the exhaust gas's displacement of oxygen-rich atmosphere, which thus requires less fuel to keep acceptable cruising AFR's.

Unburned fuel, carbon monoxide, and NOx are converted to less toxic substances by the catalytic converter.

Just block it off. EGR isn't needed, robs performance.

The EGR would be a performance killer, if it were active when you wanted power. The EGR only operates at part throttle, low load, cruising conditions. When you want performance, the EGR valve shuts. Removing the EGR will not net any performance gains.

Although, the EGR is not required for the engine to run. Blocking it off to "clean up the engine bay" or because it was broken anyways are better reasons.
