I was going to remove and clean my EGR valve yesterday, then I remembered hearing multiple owners commenting on how it's not really needed, and they remove\block theirs. I can't seem to find any posts on it on the search tool, though. Can anyone give me some opinions or help on this? Thanks.

On an 81, just for emissions and controls nothing. On later models it can throw a code ('96-up?).

If memory serves, you have 2 options. Find and purchase a non egr manifold.
or make a block off plate out of a piece of aluminum plate. The block off doesnt need to emulate the gasket shape perfectly, just cover the hole and provide something for the 2 bolts to grab hold off. Using hightemp RTV should do the job of sealing. Next the pipe side, its best to use something "coin shaped" inside the factory clamp, again with hightemp RTV. Remove the vacuum line and its associated control and SHAZAM ! you are living EGR free.

Enjoy.


When you are done be sure to remove the tag from your mattress. Its liberating.

I dunno why folks make this so complicated :

ALL OM616 & OM617 engines :

Just jamb a BB into the vacuum hose leading to the EGR valve and that's it ~ even if the nosey State Inspector pops the hood , he'll never know and you'll never get a ticket nor will it ever be a problem and yes , ' Non Compliance ' tickets DO happen and many don't want to buy your old car if it's missing parts no matter how much better it is to have them gone...

If you're supremely lazy , just remove the hose leading from the themostatic control valve to the EGR valve and be done with it .

Not being extremely lazy, but more of the "Gotta mess with it" group, I prefer to have a box of "removed stuff" on the shelf and have various mods because "I could".

I am also fond of the notion that a less cluttered engine bay makes for inner peace.

Of course ;

I'm just one of hose cobby old Mechanics who hates " extra parts " although I have way too many I've collected and keep handy ' just in case ' ~ those really are" extra " not ' gone missing ' from my personal rig .

Buy a 79 SD. They didn't have EGR valves.

I like the BB idea. Cheap, easy and no mess. (Except the oil that's all over the EGR valve. BTW, after spraying it down with PB Blaster yesterday when I was doing my valve adjustment, the car seems to be shifting better today. (It hasn't been wanting to shift from 2nd to 3rd, or 3rd to 4th without letting off the gas "more than normal".) Could that be from the cleaner EGR, or from the valves being adjusted?

Probably from changes to the non-existent Bowden cable or rod you messed with when removing the valve cover???

I tried the bb, but then I thought, "hmmm, how do I know the valve is closing properly?" So I made a plate that goes between the intake and the valve out of some Al. Then once I had gone that far, I figured I might as well get rid of those extraneous vacuum lines and whatnot. I have never had any official of any kind look under my hood, and I have no reason to expect it, but I do have all the stock crap, so I guess I could put it back if I HAD to. I don't see it happening out here in the non-DEQ boonies.

No ;

It's better because now you use less throttle to go the same speed so the linkages are all working in concert like they're supposed to .

This is why one *must* dot every 'i' and cross every 't' before tearing into anything else when you're faced with a problem .

If you don't like the look of the valve underhood, I still offer the kits to remove it completely.

If you are OK with the look, just disconnect and plug the vacuum hose that leads to the valve. The valve cannot open and EGR is effectively eliminated.

This only works on the older vehicles that don't have computer controlled EGR (all vehicles '87 and prior).

You can easily make your own kit to disable it with about $1.50 of materials from any hardware/home store....such as I did one one of our SD's.

If this saves me some time, do tell.


and the picture above doesnt show the tube connector being blocked. What of that part? I have seen a coin shaped piece used to block this with the factory clamp.

Yeah I had not blocked that yet when I took the pic. I used a couple washers held in place with the stock clamp. Works great.
