I have a 1992 Oldsmobile regency 98 3.8l v6 non turbo, and I am trying to replace the egr valve. The kick in the pants is, I can not locate it on this car. This is my parents car so I'm not 100% familiar with the diagrams from Google are not helping, any ideas where it located?
Find the transmission dipstick/filler tube. Immediately forward (towards the front bumper) of that is an electric-motor looking thing about 2-3 inches in radius with an electrical connector on top. That'* your EGR valve. Next thing forward of this should be the plastic beauty/sound cover.
Careful with the gaskets. Get the old one all the way off before you put the new one on.
