Title: EGR Valve replacement
Post by: scubasteve65 on January 20, 2008, 09:37:52 pm

'78 1500 250 6cyl 3spd. Anyone know how EGR is attatched? Some are flanged with bolts. This one is not. I don't even know where to put a wrench on it.

thanks for the link. At least from that picture I can see there is some place to put a flat wrench on it while I loosen it from the other.

Did you remove the carburetor?

Not yet. Going to have a better look when the sun comes up.

I took a closer look and got it. You can sort of see it in one of the above pics.  It's a flat 2 tine fork that has a single bolt to the manifold and it reaches across and presses on the top and bottom side (which I could not see). Stupid set up.
