I spent about an hour cleaning carbon out from around the hole - about 1/4" worth! There was a large recess routed in the baseplate around the hole that was completely filled with hard crud. I also scraped out a lot of sludge from the chamber in the baseplate. The valve functions under suction so I guess it works. Many thanks..

I barely passed smog the last time around and next month is smog check time again here in lovely CA. I have been replacing all hoses and checking various items. I puilled the EGR valve off and the underside is so carboned up that I am not sure whether it had a sealing o-ring or whatever underneath so I figured that I'd just replace it. The recess in the base casting that the valve plunger operates in is almost completely filled flush with either crud or something else. Would you recommend just cleaning it? How is it supposed to look on the underside? Is there an o-ring or can I just scrape all the stuff out? Yes, I have a California carbed EA82. Would you have an idea as to what the correct aftermarket EGR replacement would be if I need one? Thanks.

Hello All, I have a 1985 GL 4WD California wagon (which I bought in 1985...) and I am replacing the EGR valve. I purchased this partl: http://www.ebay.com/itm/Standard-Motor-Products-EGV329-EGR-Valve-/151283065586?pt=Motors_Car_Truck_Parts_Accessories&hash=item23392c62f2&vxp=mtr off of eBay which states that it is compatible with my vehicle. The only problem is that it comes with a selection of "orifice washers" of which you are to select the correct one from a chart which lists the part #'s that should be stamped on your original part. The problem is that none of the numbers match what is on my EGR valve. I think that it's the original or an original replacement. It's an Atsugi part AEY78-11 5311A. The underside of my part is in such bad shape that I can't tell if there was some sort of rubber washer or not and the plunger doesn't look anything like the replacement. Does anyone have a clue as to which washer (or orifice diameter) I should choose? Your help would be appreciated. Alan

85 4WD GL Wagon. Mine works well and I use it anytime I have to stop on an incline. It's especially useful in San Francisco where people hang on your butt at uphill stoplights...
