Lt1 1996 z28: Egr

Gentlemen: (Especially Shoebox & Injuneer who have helped me before

I am new to my car and admit the car is very techy but I can not FIND MY EGR! Shoebox usually has pics but the ones I found dont tell me where it is. I know it is in back of engine but it seems nothing is accessible back there. So, how to get at it AFTER I find it? Thanks.

What timing. I just relied to OP post on another forum with the same link. Post times probably identical.

I replaced mine on my '96 a couple weeks ago because the one I used for my rebuild was used and turns out didn't close completely. Replacing it wasn't as bad as I expected, as long as you know what you're up against and can work by feel as opposed to sight. It probably only took me 15 minutes to replace.

Re: Lt1 1996 z28: Egr

It's helpful to know there are two studs that hold the EGR valve to the back of the manifold. The nuts appear to be 1/2", but some claim they are metric. The valve may be hard to remove even after the nuts are removed from the studs. There is a metallic gasket that sticks solidly to the manifold and valve, given all the heat that it handles. A pry bar may be required.

The only connection to the EGR valve is the vacuum line, which pulls right off.
