I moved to California and shipped my 1990 Grand Wagoneer with 68k miles out here. I've had Cali catalytic converter, new carb, etc. replaced to pass Cali Smog but mechanic now says EGR valve is bad. That valve is discontinued and is different than most EGR valves because it has 2 nipples, one on top and one on bottom. It's # 5300 6332. I've looked everywhere and am out of options. Any ideas on where to find one?

I am unaware of anyone who makes that EGR any longer.
CA ARB website has a phone# for parts locating assistance.
I was unable to locate a replacement so just swapped on an older style.
However my 90 has passed CA smog several times with an older 88-down EGR valve.Last edited by babywag; 05-10-2019, 09:22 PM.Tony

If I understand correctly the old ones have a transducer of sorts built in. The transducer on the new ones just passes vacuum once a certain exhaust back pressure is reached. The old ones do this too just with internal springs. I think the reason for the change was that the old ones were a gm part and Chrysler didn't want to keep buying egrs from gm.1983 Cherokee Laredo. 360/ 727/ np228/ Junkyard 7427 TBI/ Msd ignition

Yeah, the smog techs I have gone through, lifted my hood, poked around a little, made sure it was still a 2bbl, then dyno'ed it. You also have to pay for the evap test so make sure you are ready for that. The smog techs see so few carbs anymore, they just don't care enough to crack out the book and start verifying stuff. I have an operational late 70's/early 80's transducer I would sell you if you install an early EGR and have problems with it.
When I got mine running, I had a slight off idle stumble without the transducer. So install the early/single nipple EGR and drive it. If you notice an off idle stumble, install a transducer.Chuck McTruck 71 J4000
