How To: clean the EGR

[fyremanpat]

Here it is

and after pulling off, this is what 120k looks like

and a good amount of carbon build up

after cleaning with steel brush and carb cleaner

and after bolting it back on the idle was smooth as margarine...

I strongly agree to putting a new gasket in afterwards...

Maybe im slow, but im not seeing it in the first pic. could you point it out? I would like to do this as well

 

[fyremanpat]

Well this could save me some money, I was just looking for a new one...

I found a couple on ebay, new for $98 shipped and another one for around $60...

But hey $60 or $98 is still money that I can do other things with....

I'm gonna try this, maybe this weekend when I do my rear brakes...

Thanks

Did mine today, out of boredom really! 89k miles, I used a dremel with a nylon brush mandrel and scrubbed out the inside of the housing then blasted it with brake cleaner.

Also did the IAC while I was under the hood. Started up and idled fine, but it wasn't lumpy or erratic before. I'll see how it does next trip into town....see if it feels any different.

I did mine today as well as the IAC. I used Tahojim's dremel idea and intake cleaner to get inside the body and clean it out good. That's a really good idea, it works well!

You wouldn't believe the amount of black crud that comes out.

I havn't tried this stuff out on the highway yet today, but I'm anxious!

Is it possible to block the egr? Also wouldn't it give you more power if one did? I only ask cause my friend did that to his truck and he cold feel it more in the accelaration.

 

[bigfeet]

What is IAC?

 

[nurkvinny]

Idle Air Control.

Blocking the EGR is suppose to give more power for a Turbo car. Not sure about an NA truck motor. I think the benefit is not having the hot air recirculated into the intake, so I don't know how much difference could be had. Also, on an OBDII vehicle, not having the EGR working will throw a code.

Will cleaning it remove the code thrown for EGR?
Just bought truck with EGR CEL on, havent checked actuall number thrown but I will by tomorrow. Previous owner said it was EGR???

Might but not right away. Depends on code.

[saif najd]

I did it but I didn't feel any change

 

[SunlitComet]

Perhaps you just did not really need it then.
