I had my EGR valve replaced by a mechanic, but it was defective. he refused to replace it, and I wasn't about to pay another mechanic to do it. So I replaced it myself. But I'm adding this video to my favorites, so that I can learn to keep this EGR valve clean and functioning well for years.

I don't want to spend oodles of cash at the shop when I can do most of this myself, and having mostly older vehicles (1990 F250 XLT, 1998 Nissan Sentra [insert sad face here], 2000 Mazda Protege) I would be spending more than just oodles to get them running decently again. I'm getting a bit more comfortable tackling larger repairs, and I wanted to thank you for making these jobs a little easier to handle. Keep up the good work and REV THOSE ENGINES!

[@holidayhouse03]

Took my '94 dodge colt to 2 different professionals who couldn't diagnose why the car was running poorly. I started doing some googling and youtubing... thought clogged egr sounded right. Man that thing had chunks of carbon coming out... ran like a top after that. Learned something about my car and " professional " mechanics

[@DrUndies]

Did they still take your money?

[@holidayhouse03]

Pep boys billed me $100 for an hour diagnostics... they got it to run a little better for a little while. Come to find out they did that by fully advancing the distributor/timing. My neighbor who worked at an indie shop did not charge me... he swore it was a temp sensor. I only own rwd redblock volvos now and diy what needs done... very simple cars to work on.

[@tyny3620]

Randi Evans yes a faulty or dirty EGR can cause rough idle, stalling, and decreased mpg

[@charlespratt8663]

Scotty, you should have told folks to check the EGR passages into the block etc. They often plug with carbon and need to be cleared out.

[@sanurshenoy5739]

Scotty, you are a genius. After viewing several other videos on EGRs, some even with 3D animation, I understood EGR from your video better. Thanks.

[@oldowl4290]

On this particular V6 Toyota engine that he's working on, the old 3VZE (which I have) also exists the EGR probe (~6" long) which goes inside the intake plenum next to the EGR. That should be removed and cleaned as well as it gets corroded with deposits. And as you will see, there is also the EGR Modulator in front of the EGR which looks similar in that it has a round top. The EGR Modulator has 3 vacuum hoses (P, Q, R). There is a small disc-shaped filter in the top of this unit and it should be removed and cleaned out. Other things to look for in this smog system are the PAIR reed valve unit (further behind and lower from EGR), the Evap "charcoal" cannister on rear left fender, and lastly, check the inlet / oulet temps of the Catalytic converter with a laser thermometer which should be ~80 to 100 degrees in difference for a working cat If under 75, the cat is on its way out.. If under 50..replace it! Replacing the oxygen sensor down there is also not a bad idea. Those are all the main smog items on this engine.

You really don’t want to soak the EGR valve upside down - that diaphragm is made from material, not metal, and the carb cleaner or solvent can actually destroy that. It may also be a good idea to try to clean the passages that you see, when the EGR valve is off the car, as carbon can block those passages as well.

[@Chevy-hw6lw]

@Rob in my case I already have an ultrasonic cleaner , so it makes more sense to clean it, assuming the diaphragm still functions . Even if you didn’t have an ultrasonic, it would still be better to clean it than buy a new one... again assuming the diaphragm and valve works .

Mine had a gasket between the throttle body and the EGR valve, don't lose it when cleaning the EGR! Also, it might be a good idea to clean the throttle body when there is a problem with the EGR, mine had to clogged holes that came from the EGR valve :P

[@stevebutler812]

Exactly- if those passages to intake or from exhaust are clogged- then there’s no / low flow. I think that’d cause the p0400-09 EGR insufficient flow codes- even with a good EGR

Scotty, some egr valves have a built in bleed, this will keep the valve from sticking open all the time. A vacuum gauge can and will fall on most valves, the diaphragm will move but not necessarily stay up.

EGR valves are no good for a 90s model F150. You also have to breakdown the throttle body and clean out the ports where the EGR returns the gases. Carbon builds up in the ports and clogs.

[@gagapol]

Before cleaning your old EGR it is good to check first if the new one is available for a few bucks. That what happened to my 25 yr's old Sebring convertible 2.5 liter. The other valve worth to replace is PCV one, in case if it is not knocking loudly while shaking in your hand.

[@noseefood1943]

i think nowadays most cars w/ LEV and ULEV with variable valve timing don't use EGR. VVT controls enough valve overlap that the exhaust reenters into intake to fight NOx.

[@onyx7561]

I've cleaned my egr valve about 3 times, replaced it with a new one, checked all lines, and my car still runs better with it unplugged

[@max41050]

. Okay but if you bypass the egr valve won't the engine light come on ? The reason I'm asking is because my former mechanic sold me a 1995 Toyota Camry and the engine light would come on when the weather was hot but it would go off by itself when the weather was cool I found out that I had a trouble code 71 egr related I cleaned the egr valve and the code didn't go away I went underneath the car to look for the egr vsv solenoid valve and noticed that one of the little vacuum hoses was discontinued purposely my former mechanic had done a bypass on the egr and not only that the other two little vacuum hoses that are connected to the vsv valve were switched I found this out after looking at the Haynes repair manual to find out the proper location for each hoses so I reconnected the 3 little vacuum hoses in their proper place and the engine light issue was fixed . That is why I'm asking this question because I'm thinking if my engine will run better if I bypass the egr valve it might be worth doing it I can always reconnect the hoses back in their proper place when the time comes to smog the car.

Scotty....EGR question here... I bet you worked on thousand of these cars back in the day.... 1980 Pontiac Sunbird with a 2.5l 151 4cyl Iron Duke. (RWD H body, you can see it on my channel). It runs really nice, but the motor starts bouncing noticeable as soon as It goes into part throttle / steady state cruise. I tried everything and found some relief with the EGR valve. As tested it opens ok with vacuum. When I remove it and block it off completely, it smooths out the shakes, to barely noticeable. I wonder if I have a leaky exhaust valve? Idles ok, pull's fine and doesn't seem to have a missfire. (carb - no computer) but the sound from the tailpipe at idle sounds like it might have something amiss..

[@streetwiseguitar5113]

Scotty, if the EGR is bad would there be a strong smell to the exhaust?

[@resourcegyrl]

Yes, my EGR is bad on my Chevy Malibu, and it has a very strong gas smell when you start up the car! It's overpowering!

[@mridware9694]

Do every car have EGR valve ?? Like 2004 Camry and 2013 Rav4 ??

[@igotstoknow2]

No. My 2003 Elantra doesn't have one.

CauseAndEffect then it's Good

[@jessstuart7495]

Manufacturers predominantly use catalytic converters to address NOx emissions these days.

[@waynes.2983]

Those do have an egr.

[@mridware9694]

Wayne S. I checked completely only oxygen sensor is connected with exhaust manifold...

[@Mamen_75]

For those you think blanking the EGR is a good idea, think again, don't forget that it does not only lower emissions but also lowers the combustion chambers temperature, if the EGR is "deleted" the engine will probably make some pinging sounds due to pre-ignition (too high temps on combustion chambers).

pdidi1 very true on gas motors, leave it in place. Diesel? An entire different story.. it costs $1000+ to clean all the soot out of the cylinder heads and intake tract. When the motor gets clogged with carbon it ends up polluting worse than anything due to insufficient airflow to combust the fuel. This can happen in as little as 60k miles! I.e black smoke eew.

I like your green bike!

[@AmplifytheMind]

Do you have any tips for cleaning the carbon out of the part of the air intake that has the port for the EGR valve without removing the intake?
