EGR valve on 88 S-10, 4.3

How do I clean the carbon out of the EGR valve on my truck? I have heard of people soaking the valve in Kerosine, using a wire brush (both by hand and with a dremmel) and even spraying water into the TBI while the truck is runing. I tried to do a search, but the search engine would not accept EGR as a valid word (too short).

Pitch the valve, they are dirt cheap on a GM like this. A Delco valve will run you under 75 bucks.

Install the EGR gasket with a built in screen (if available for this application), it will trap some carbon and prevent the pintle from getting clogged.

Cleaning it is a hit or miss endeavor. Sometimes the carbon is so tough in there, no amount of cleaning will fix it.

WD40 works best and won't cause any damage if you do try to clean it. You'll probably wipe out a whole can trying though!

egr valve cleaning

I recently had to do this to a 96 Blazer with a 4.3 liter and it is a quite simple task that didn't take more than a half hour. Get you some paint thinner and remove the valve mine was only two bolts. Be careful with the gasket and you should be able to reuse it. After removing the valve pour the paint thinner in the two holes on the bottom of the valve and let it soak for a few minutes and then take a small brush (I used an old toothbrush) and clean out the holes and the pintle on the bottom. Mine was kinda stuck but after doing this i could work it easily with my finger. It's alot cheaper than buying a new one for 75bucks and pretty easy to do. My check engine light kept staying on and when i had it diagnosed they told me it was the egr valve and wanted $189 to fix it after the 69 dollar diagnostics.

Do not reuse the EGR gasket, you will get a vacuum leak. A new gasket should be under 5 bucks.

With that being said, cleaning some valves eventually destroys them and they require replacement. Paint thinner can attack and destroy the rubber diagphragm in the old style valves.

A 1996 ST series Blazer has an electronic type valve. Different animal.

worded for me

I did this about 3 months ago with paint thinner and reused the old gasket and it cured the problem and no vacuum leaks. It actually runs better than it did before and like i said thats been 3 months and 3000 miles ago. As a matter of fact I got this information from a Chilton motor manual for chevrolet s-10 pickups and blazers from 94 to 2001 so it may not be good for the 80's models but its worth a shot if your gonna trash it and buy a new one any way. Might just save you some cash.

As I said, the gaskets are only a couple of bucks. If it's been on there a while, it will stick to the manifold and turn to dust. My time is worth more than trying to save a 3 to 5 dollar gasket .

As I said it worked for me! My gasket was six years old and looked like a new one it never stuck at all. It took me 30 minutes to do the job and cost me less than a dollar! By the time you go to the parts store and spend 80 bucks and get back I've got the job done sittin back drinkin a beer and laughin at you!! If you wanna blow money just take it to the dealer and let them do it for about 160. I was just giving my experience I didn't say put a bad gasket back on. Oh by the way the thing about WD-40 you said earlier. WD-40 will do nothing to carbon so you just wasted a can of WD-40!

You're woefully incorrect, sorry chief.

WD40 cleans and displaces water/rust. Says so right on the can. And it DOES clean carbon out of the EGR valve. I know, I've done it. Rubber diaphragms CAN be ruined by the wrong solvent. SafeTClean would be a better cleaner.

As for reusing the EGR gasket, your balliwick, it's not proper procedure. You're asking for a leak. You got lucky, it's not mad to be reused. As I mentioned, my time is worth more than the 1.50 I will spend on a gasket, if I don't have a pack of free ones lying around . Not sure where you buy your Delco from, but I'm paying a third of what you quoted....if I don't get it for free .

Yes cleaning the valve works on SOME applications, but others are bad and have to be changed. There is a proper procedure to test EGR flow and operation.

So, while you're getting drunk on the beer and do it again in 6 months (your application is a known clogger and there is an aftermarket fix for the problem to alleviate) that, I've already moved on to the next repair.

Not faulting what you did, simply correcting the innaccuracies.

Now here's your inaccuaracies. Carbon is not water or rust "whole different animal". You need to read the whole can not just the parts you want to read. "Cleans most surfaces of: GREASE, GRIME, TAR, ADHESIVES, GUM, TAPE, CRAYON, SCUFF MARKS, WATER DEPOSITS." I see no mention of carbon. WD-40 is a petroleum distillate wich also eats rubber!! The WD did't clean the carbon off, your precious time scrubbing did. I don't know where you get your parts and gaskets for free but if you could let me know i would be grateful unless i have to steal them. Also the price i quouted was 75 bucks for the egr valve the same price you quoted in your first post and now you say you can get it for a third of that if not for free. So your saying you can get it from 0 to 25 dollars? Oh now i see why. You work for a parts company. Just because you can sell parts doesn't mean your a mechanic! The guys at Advance Auto Parts can tell me what part i need for my car but that doesn't mean they can fix it! Most people could get on a computer and search for a part but that doesn't make them an ASE certified MECHANIC. Just like an ASE certified parts specialist is not a mechanic!!

Hate to break it to ya champ, but the WD40 just by spraying and sitting there made the carbon loose and it came out. That's what WD40 does. Clean. Just like the label says.

I do get the parts for free, so you might get a clue about that before ya shoot your trap off, because I don't sell anything for a living. I get sent stuff to try out and evaluate. And, not only do I know how to fix cars, I WRITE the catalogs the parts guys use. So, I don't have to go to the parts store and ask for what I want, I simply tell them what to pull off the shelf by part # . The price I quoted is what most folks will pay over the counter. Not everyone's in my position, so get the facts straight before ya yap.

Newsflash: If you've bought an aftermarket auto part, you're talking to the guy that introduced it, priced it initially, decided the packaging, instruction sheet for it, researched the OEM. I have my finger on the pulse of what's going on out there and I own six cars, fixing them all.

So once again, not only can I tell ya what part # ya need, I can tell ya what's going to fix it. That's why I've got moderator in my title bar

So back to the subject:

1) Reusing EGR gaskets is bad practice and not proper procedure. I follow proper procedure, that's why I don't do things twice.

2) The problem with most EGR applications is carbon stuck in the pintle. Newsflash for you: It's going to happen again on your vehicle, it's a common problem on GM electronic valves. So much so, there are gaskets with integral screens to prevent this from happening again.

3) You could clean a valve and it could STILL be bad. That's why there are OEM test procedures for STO values and flow.

4) Luck is not proper procedure, nor will you see me prescribe it on my forum. When your name is on this forum, if that comes to be one day, you can recommend the reuse of EGR valve gaskets...even though the OEM says otherwise

One thing's for sure, your grammar and spelling suck. And so does your attitude. In my book, you struck out a long time ago. Have a seat, chump.

Newsflash #1: I don't sell parts. Read my profile.

Newsflash #2: I don't sell parts. Read my profile.

Newsflash #3: I don't sell parts. Read my profile,

Newsflash #4: I have nothing to gain on a 2 dollar EGR valve gasket. Maybe you do, or are just too cheap to buy a new one .

Newsflash #5: I have worked on more cars in a day than you will drive in your entire life. Not to mention I do plenty of things on cars that folks farm out. Please tell me the complete rebuild procedure for a 10SI Delco alternator? Or do you just buy rebuilds from the parts store? Shame on you, I completely rebuild my own. Now who pays who to do the work?

Newsflash #6: A pinhole in an EGR valve diaphragm occurs from age.

Cleaning it CAN ruin it or make it stick worse as well as lodging carbon on the pintle and shaft making it stick. But if you had a clue, you'd know that the valve in your S10 and Antony's are a different animal if you read a parts book wouldn't you? Sure you would. Get a clue. Yours is electronic, Antony's is vacuum. Different animals.

Now, moving on, let's hear what Antony has to say about his problem. It may not even BE the EGR valve.

So, sit down, close yer yap and listen. You might learn something. Let Antony report back and let us know what he finds.

Step 5 on EGR cleaning from Autolibrary:

Clean the mounting surfaces of the intake manifold and the valve assembly, then install the valve using a new gasket.

Note the term use a NEW gasket. Chilton does not sell parts, so tell the group, how do they benefit from that statement ?

With that in mind, this post will be closed if Antony doesn't reply that he needs more help.

Well I'm glad you know it all!! I just don't use my good spelling and grammar on an egotistical self- centered ass such as yourself. I looked back and some of the threads that you have posted on and also received some messages from people that have seen this one and i've determined not many people like you!! Maybe you should be nice and then maybe you would make friends!! YOUR ATTITUDE is the one that sucks!! You argue too much!!! They should call you RULEBOOK!! Hey do you have one of them sex manuals to make sure you're following proper procedure???

Hmm, I get e-mails thanking me for the help I provide. My comoderators, friends and even the forum administrator have backed me up. How about yourself?

I'll ask you to keep your extra curricular activities to yourself. No one wants to hear about your love life problems, nor are they relevant for automotive repair. If you feel the need to relay your sexual frustrations, please take your problems elsewhere, not on the doityourself forum (Hey, maybe you like that, you fixate so much on it? ) .

But, enough time wasting with your issues. Either follow the rules or leave. Or you'll be asked to leave. Your choice, pal.

Nor should we follow your advice about reusing EGR valve gaskets as all the authorities on auto repair disagree with you.

With that in mind, what about the altenator rebuilding procedure I asked you about? What's that? You don't know HOW to rebuild your own alternator.

Shame, shame, you should shelve your pride and ask. I might even tell you if you behave. Others on this forum now know how to do it as I have instructed them .

With that in mind, who's the dunce without the knowledge?

Newsflash: You can look in the mirror. Do us a favor and don't breed until your attitude changes for the better.

Hey joe on that alternator!! I'll take your usual advice!!
Joe F: "just trash it and buy a new one. I don't know how to fix the one you got. DUH!!!"
You can't even put a plug on a hair dryer without argueing with the electricians on here!!!

If you had half a brain, you'd know that the item in question was not a hairdryer. It was an Oster blower/vac. But, your reading skills suck too.

With that in mind, once I got the proper polarized plug, I did it in five minutes. I also called Eagle Electric and the guy also answered my questions. Another PROFESSIONAL, not like yourself. Now, being that I have a clue, and you don't I take what the pros say before some clown that tells me to reuse a two dollar expendable part. Ya see, I learn by asking and do my own homework, and the job is done. The problem is elsewhere on the Oster vac. Yes, the thing you erronously called a hair dryer.

By the way, how come Chilton doesn't agree with you? . It says use a NEW gasket.

With that being said, tell me, why is it you have to resort to name calling when I've proven you wrong, not once, twice, but three times?

Please don't insult my intelligence or anyone's on this forum. You bore me with your stupidity.

I can't imagine you taking anybody's advice!! Your grandfather told you in the beginning it wasn't the plug!! If you would just pay attention!! I said along time ago if you dont agree with using the old gasket than don't!!!!! I was just giveing my opinion!!! and what worked for me!!! You are the one that keeps comeing back with your know it all attitude!!! I haven't seen anyone yet that has come on this thread and agreed with you!!! If they do i'm not gonna start argueing with them unless they attack me like you did!! I thought this was a forum for advice and help not a debate!! As far as i'm concerned Anthony can take whoever's advice he wants but you are still a self centered egotistical ass!!
I'd like to take a poll to see who agrees. Can you set that up for me Joe F????

You're an ass. Plain and simple.

The plug was exposed and the prongs were bent. It was unsafe and being changed. Newsflash, since you can't read: Never said the problem was the plug. It was ONE of the things I wanted to fix. But go back and read the post.

I'd rather be egotistical than stupid, so take that one to the bank, chump. It's been proven you have ZERO common sense and grammar skills.

As stated before: Reusing an EGR gasket is an opinion. It's the wrong one. Do you reuse your oil filters too? No. Toilet paper? No. Dirty underwear? No.

Point made. Don't reuse EGR gaskets. Period.

If you could read, "Anthony" is really "Antony", but I suspect you cannot read or even comprehend that.

I'll tell ya what I can and will arrange. Don't worry, it will be coming your way soon .

I agree with ejones!!! You have turned a 3 dollar gasket into your own personal vendetta because somebody had an opinion that wasn't yours!! Just like most of the other threads you have given advice on where somebody gave an opinion!! Who in the hell gave you moderator title anyway???
As far as my grammar goes are you an english major too???
I know some french i'd like to teach your sorry ass!!!
Was that a threat there at the end?? Like most of your threads when someone gets the best of you, you wanna end them!!! so what now are you going to ban me??? I have had some intelligent conversations with some great people on here and learned alot also!!! Believe me none of those conversations were with you!!!!

Don't try to enlist me into your sordid little squabble. I was directing my comments at you, NOT the moderator.

It might be best if you carried on your obvious personal vendetta via direct email rather than continuing to stuff-up a useful DIY forum.

Just go away.

Enuff said i will take my questions and advice elsewhere. I wasn't trying to enlist you i was agreeing with you!!!! Joe is the one that made a big deal about the gasket and started the argument!!! We both gave opinions and he didn't like mine!!!!
So what!!! Say you disagree and go on!!! No need for the smart remarks and the know it all attitude!!! I admitted my mistake and agreed with him a long time ago about the gasket but he still kept on about the gasket!!! I'm sorry my gasket looked like new and i was able to reuse it!! No big deal!! I took into consideration that he would be able to tell if the gasket was bad or not. My mistake!!! No i dont reuse toilet paper,but i do wash my underwear and wear them again!! I don't throw them away and buy new ones everytime!!! Hey Joe do you have the OEM specs on how long to keep a pair??? On this forum i wouldn't want to not go by procedure!!! Oh by the way ejones it should be DIJ board: Do It Joe's way!!! I've read some of your posts and learned a thing or two about computers. I was very impressed with your advice and wisdomed!!! I am always willing to learn that's why i "came here"! and maybe give some advice not argue with a so called "Moderator" aka Joe_cool
