Question For Yodawill2000

on either side of the motor there is a metal pipe that comes from the back and does a 90 degree turn straight up into the Intake Manifold.Dont recall the size but two small bolts mount it.I took out the bolts and pushed down on the pipes just enough to get them out of the manifold then pulled them to the side of the car to get at them. Please note the opening is NOT at the end of the pipe.There is a hole on the back side of the pipe.Mine was totally plugged with carbon and oil looking stuff.I got it out with a small dental pick and a shop vac, trying not to get any dropped into the pipe.Havent had the Check engine light on since.I suppose I was lucky it wasnt the end where that pipe goes into the EGR at the top center rear of the engine.Looks like a bugger the get that end loose.

Hmm.My 94 doesnt have those that I know of.The pipes Im talking of come around the side of the engine from the rear then turn straight UP into the Manifold.Let me go pop my hood and refresh my worn out memory.

[yodawill2000]

My bad , I do have those ,, Duuh ..No those arent the egr pipes Im talking about.Look at the bracket that supports your Oil Dipstick Tube,You will see a small pipe behind it that goes down and turns to the rear. Thats the one , Other side is just like it.I recall now taking the bracket bolts out before I could get to the passenger side pipe.

I'm afraid not, my friend. The tube in your pics take may be 5 mins to take out and put back, but the tubes that yodawill2000 was talking about are in the back of the engine connected the EGR valve to the both side of the manifolds. Which took me 2 hrs if not more to replace for a fellow Nico Member in my area.here is a pic of the one on the passenger side, and you have one more on the driver side, too.a pic of a new one side by sideWhat he meant "by plugged"

[yodawill2000]

I didnt take mine out ..Just pulled the front part of the tube out of the manifold.As you see in Pic 3 there the holes on the side were COMPLETELY clogged.I originally planned on taking them the whole way out and cleaning them with oven cleaner as Wes advised but QUICKLY learned the connection of the pipe to the EGR would be a Beootch to get off.Been almost a year and no EGR function errors yet. ~~Fingers crossed~~

My understanding is the flow is from the EGR in back to the front.The reason is to recycle some exhaust gas back into the intake.I agree the it seems that the whole pipe can get nasty. I just need to have a full day when I can get em' out.Busy as a one armed paper hanger lately.

[NismoChi]

Yeah, it would be a PITA to clean them, but i just thought of something last night, may be a power washer from a carwash place can blow all the junk out real quick.That why i adviced that fellow member to buy some new tube instead of trying to clean them.

[yodawill2000]

The problem is getting them loose at the EGR end. Anybody know an easy way to do that ?A metal pipe shouldnt need replaced if it can be cleaned.Basic Logic

[Jakw]

Reviving a dead thread, I know, but I can't get the egr tubes off, even on the manifold side. It seems like there's a bracket in the way on both sides. So...how did you that have cleaned these get them out from the manifold enough to clean them? Just take those brackets off?

The only bracket I had to remove is the dipstick mount.You are taking out the two mounting bolts on the flange for each pipe right ??

Scott did his just yesterday.they can be a bugger to pull out.They make a 90 degree turn straight up into the manifold.Fixed his CEL too !

Yes, I did mine yesterday, and yes, it is a royal pain.

There is a bracket that has to be removed. One on each side and you also have to remove the dip stick bracket. Once you get that off it's not too hard. I just scrapped out the goo with a paperclip and then hit it with a shot of brake cleaner. The only other problem I had was that the pipes didn't want to go back in the holes. I had to bend them back in a little to get them to fit.

I had a solid check engine light on all the time and the first time I cranked it up after cleaning them out, no light. Has been fine for 2 days now.

Got the J all fixed up and now I get my Durango back. The wifes been enjoying the 340 ft lbs of torque and I want it back darn it.

Alright, cool. I couldn't reach the brackets that need to come off with the wrench I was using, so I guess I'll have to spring for a socket set or something. I wish I had the time, tools, and space to take the tubes all the way out, but I think I'm just going to do some scraping, and probably spray it with some carb cleaner. A mechanic wanted something like $800 to clean the EGR system. I'd rather just do an easy, if less thorough job for the cost of a ratchet and some cleaner.As long as this thread is up...anyone looking to make their car run better, cleaning the throttle bodies and the MAF will help a lot. Once I get this CEL to go away, I'll be a happy camper. Oh yeah, anyone run Seafoam not through the brake booster? I think that only cleans up the driver side.

Like I said, I wish I could, but I don't have the time or place. If I break something and my car is down for two days, that's two days of work I miss. I'll have to settle for opening them up.

[gr8scott72]

The only way to clean these tubes good is to remove them. You can "open" them up while they are still on the engine. Opening them up will work, but they will clog back up faster than if you were to remove & clean them.

Mine went 190k miles before clogging all the way. If they clog up faster that will probably mean, what, only 130k miles to go?

I'll pass on the $800 repair to keep them unclogged for the extra however long it end up being.

[Jakw]

Well, it took me about an hour and a half to clean the passenger side tube today. Oddly enough, the hole wasn't clogged like in the picture in this thread. I went ahead and shot a little throttle body cleaner into it, and after two or three bursts, it sounded like it was filling up. I ended up snaking a low E guitar string (the thickest one) down the tube a bunch of times until it came out relatively clean. I'll get to the other one tomorrow, and hopefully I won't have to see the check engine light anymore. This was a helpful thread, so thanks.

Yeah, it was EGR. And the light went off after like a two minute drive. I'll still do the other side tomorrow.
