Could anyone tell me where the EGR is on a MPFI Camaro 2.8L? pictures or text?

Mine is a 3.1 and has a different EGR valve, but the location is the same. Pictured below, there is a gold colored accordion tube behind the alternator, follow that from the throttle body to the other end, your EGR is there at the end.

Its mounted on top of the passenger side exhaust manifold. Its got a wide round shape to it, think of a UFO, lol. It will have a vacuum line coming off it and the accordian tube like described above going to the intake manifold.

here you go, it's the black thing just behind alternator. I know the other guys did a good job of describing it, but here's a pic anyway


Why are you changing it? If it's for a code 32 from your ECM, most of the time those are caused by vacuum leaks, not a faulty valve itself. I was throwing a code 32, and it turned out my EGR solenoid had a crack in it

Im tesing the value to see if it faulty or not, it kinda pisses me off when im cruising down the highway and the service light comes on, it takes about 20mins of driving till it appears

Mine did the same thing, and it ended being a leak.

travisgold

if its a leak i probably wont fix it to be honest haha dont have the funds or the time just want to drive the damn thing, it might be a leak though i sometimes smell exhaust inside the car but i think it was because the cars vents where open, btw i really like the colour combo on your car!

thanks!

by leak I meant a break in one of the small vacuum hoese under the hood. easy to patch with a small rubber line

finding it is difficult

travisgold

no problem, found the EGR lines, dont really know how to test them though do i just remove the black connectors then start the motor and move the throttle manually? or what i dont remember lol ill look in my chiltons manual again or my haynes

I really don't know. I just found a crack, and replaced the part.

travisgold

oh i see thank you for your help though, have you had any problems with your wind shield wipers by any chance? thats my next problem im attemping to fix the high wipers dont work properly the motor will turn but the linkage arm will just jump and the wipers will move about a cm up and down the wind shield

iTrader: (3)

no, I haven't. Wiper transmission might be out, or the wipers could be mounted loosely, causing them the spin on the base instead of move

travisgold

could very well be hard to tell those cowl screens are a bitch to take off

travisgold

what did you use to shine up your motor anyways i want to shine my motor as well.

filing, sanding, and polishing.

travisgold

thank you so much, in about a hour or half i need to post another problem i have been having with my car... its been making a whining noise when i start it up and it wont go away till the car is physically moving then it wont come back until the car is cold...

odd.. i'll look for the thread...post as many details as you can. maybe a video clip

travisgold

thats what im planning on doing in a few minutes is go out to my car with my iPod and record the noise when i start the car i dont think ill be able to move the car considering the position its in the driveway and the truck is to close to it and i dont feel like asking my dad to move it but ill see what i can do in terms of that.its just the strangest noise it never used to be there it sounds like maybe a whining fan of some type but that doesnt make sense because i never have a fan running during startup

Hi.
New to this. I have a 2.8 with a vacuum line I cant find where it plugs into . It comes from the Vac reg vale and is showed in your photo running in back of the plenum.
If you have a photo would be great.

Thanks,
I got the vacuum diagram. It shows the line coming off the Vac reg vale goes into a vac switch. I researched the switch with different parts and cant located on my car. Hoping maybe someone could show me a photo
of it to help me out .

It must be the hvac vacuum line

Hi,

Thanks for the reply. Looking at the diagram not sure if that is it.
Photo would really help (vac switch)
