Aaron_Johnson Posted April 25, 2008 Share Posted April 25, 2008 does anybody know how to decipher the date codes on egr valves i have found an egr valve application part# page which gives a part# but the date code is a bit of a riddle.

DwayneGorniak Posted April 25, 2008 Share Posted April 25, 2008 When you are looking at the top of the valve and you see the two lines of numbers, the bottom line is the date. The first three numbers are the day of the year. The fourth number is the year. And the last number doesn't mean anything. The only reason I know this is because we had some EGR valve reapirs kicked back from WEPEC(warranty evaluation parts whatever center) and they were telling me that that dates on the valves were newer than the truck. So I checked OASIS on these trucks and phoned WEPEC back and chewed them a new ass. Some of these trucks had the EGR valves relaced two or three times. So it is possible to have an 05' or 06' or 07' built valve in an older engine. After asking these Idiots if they had any frickin idea how many egr valves we change on these damned engines, they got the point and paid all of our kicked back claims. I don't know what the hell the rest of the numbers mean. Quote Link to comment Share on other sites More sharing options...
OHNO60 Posted April 26, 2008 Share Posted April 26, 2008 BOY FORD LOVES YOU CANADIAN TECHS! THEY ALWAYS SEEM TO BE UP YOUR ASSES ABOUT SOME SHIT LIKE THAT. WHY SHOULD DATE CODING BE AN ISSUE? IF YOU NEED AN EGR VALVE AND YOU GO INTO EITHER PROQUEST OR CATALOG ADANTAGE IT NEVER ASKS FOR DATE CODE.JUST SPITS OUT ONE OF THE 2 PART NUMBERS. TO MY KNOWLEDGE NEVER HAD AN ISSUE LIKE THAT. I DO KNOW DATE CODING MIGHT BE MORE CRITICLE DURING THE 04-05 PRODUCTION DATE CHANGES.AFTER THE 2005 THEY COME AS ALL THE SAME 5C2Z. I FEEL FOR YOU GUYS TRYING TO MAKE A BUCK OUT THERE!

Aaron_Johnson Posted April 26, 2008 Author Share Posted April 26, 2008 Thanks Dwayne, that is exactly the same problem we are having. I think you are right that they are missing the fact that these engines have all had the valves replaced more than once Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 26, 2008 Share Posted April 26, 2008 Maybe I am just lucky, perhaps a little skeptical, or just plain cynical - I have yet to get a "bad" EGR valve out of the box. This goes for my whole shop. I recently worked on a Econoline that has has 4, yes, count them, 4 EGR valves installed in the last 6 months. It took me ten minutes to find that it had a poor connection at pin #33 at the engine PCM connector. The van came from another dealer who tried three times, one of my guys ripped it apart the fourth. With all of the chatter about EGR valves supposedly being bad I would think there would have been an SSM or something bringing attention to the subject... as for the HotLine telling us this, I wonder what their basis is. I look at the HotLine like a computer, garbage in, garbage out. I think a lot of techs calling in are simply wayyyyyyy off track by the time they call and the engineers can only go with what is presented to them. They don't have the advantage of actually seeing the vehicle hence, they rely on the garbage some techs are feeding them. The result? Garbage out. I may be wrong. I am venting. I am tired of cleaning up after "stupid!" Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted April 26, 2008 Share Posted April 26, 2008 Kieth, I think you are quite right about Hotline... I call these guys looking for any "known" (aka "reported" concerns)... I also call these guys looking for a knowledgeable "sounding board"... Often, they will give me an epiphany... the tech will say something that strikes a chord. By and large, many that call Hotline are looking for a magic bullet... "take my pain away and make it so I don't have to think". As for the EGR valves... Both my diesel techs have had occasions where the first or even second one has given concerns right out of the box... Then we find the "magic" EGR that fixes the concern. Have they checked for spread pins? Other than visually, probably not. (I'm talking take a probe and check the effort it takes to insert and remove it). But we do find a valve that is going to work... eventually. Back in the 70s, the workplace was festooned with posters proclaiming the benefits of "zero defects"... perfection, if you will. Once they realized that the human animal is incapable of perfection, it became common for the consumer to be part of the "quality control" process... I might be off the mark here.... but for any given automotive product, there are only so many manufacturers. I have this mental picture of an assembly line producing <your part here>. At the end of this assembly line is an underpaid recent immigrant from God knows where... happy to be in North America. It is his or her task to take the final piece and assign it's destination (remembering that they have no idea what this piece is... only that it is clean, usually shiney and that it is a car part). This one is pretty good... it goes in the OEM pile... this one is iffy, it goes in the aftermarket pile... And the cnsumer remains to be part of the quality control process. There are no truly "guilty" parties... this is the vagary of "mass production". If we hold tolerances to closely, the price can skyrocket... Loosen up the tolerances, and the prices can "mellow"... But we run into a problem when part "A" is too big and part "B" is too small... Yes... my week was a ball of sh!t.... /forums/images/%%GRAEMLIN_URL%%/crazy.gif Quote Link to comment Share on other sites More sharing options...
DwayneGorniak Posted April 26, 2008 Share Posted April 26, 2008 Aaron, Make sure you phone those pricks and tell them to shove it up their arses. They don't have a freakin clue. And keith, keep in mind our winters. We can change a valve in the fall and by spring the damned thing can be plugged solid from a large amount of factors. Our average cetane rating across Canada is 35. So piss poor fuel, sometimes extreme amounts of idle time, babying these things or even the fact that alot of these trucks go up north all winter in live in minus 40 to minus 50 degree celcius weather. Even cold injector missfires contribute to this as well. Start these things up every morning and they are barely running and slobbering like hell. Yeah, we change alot of valves. But we also have other causals. It is not always just the fault of the valve. We have to always get to the root cause. Which is why I do the coking TSB all the time. However, I have had maybe a handfull of bad valves right out of the box. Damned mass production. /forums/images/%%GRAEMLIN_URL%%/2cents.gif Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 26, 2008 Share Posted April 26, 2008 Dwayne, this isn't about coking for me, it's about not properly diagnosing on the premise that the part can be assumed as defective. This brings be back to the topic post and EGR valve build dates. So, if there are a bunch of EGR valves that Ford suspects are bad (enough to cause problems) then why not pull them off the shelves, put out some sort of official notification indicating the affected parts?

DwayneGorniak Posted April 26, 2008 Share Posted April 26, 2008 That would be a great idea Keith. But I fear the warranty Nazi's now control most of FOMOCO and will do anything to not pay out another dollar. They are kicking back crap like this and don't have a damned leg to stand on with this issue. Quote Link to comment Share on other sites More sharing options...
