To get a "better" diagnosis, replace needed parts (probably the entire EGR assembly), etc. for a shop is going to cost a couple hudred bucks. Or... you could pick up a 50-state legal Mopar PCM used for $150 or so. Eliminates the need for the EGR system (and will never throw codes for it), adds a little power. Still runs on premium, so no change there (for DOHC's). At worst, you might want to spend another $20 on an EGR block-off kit if you are having start-up and/or idling issues because of the faulty EGR system.
Best of luck!

Why would you want to block off your EGR???? It will help your car get better mileage and not cost you any power doing so.

I am pretty sure I read that the EGR is used for emision purposes, which is good but Im sure I read that the EGR re-circulates hot gasses back into the intake where they are run back thru the engine.Kinda defeating the purpose of the CAI, RIGHT. If I am wrong plz let me know.
If it wont help the car run cooler or if it don't help me out in any way PERFORMANCE wise feel free to talk me out of it, LOL........short of that I will be makeing my EGR block off plates at work.SOOOOOO easy.

I still get 38+ mpg highway (and a mere 32-34 in town) with the EGR blocked off. Not too concerned about a couple of pennies every fillup since I have to use premium anyways... The biggest reason for blocking off the EGR is to stop the nasty coat of black goop all over the inside of my TB (making the IAC stick), intake manifold, intake ports, and intake valves. Sure, a can of Mopar Combustion Chamber Cleaner every now and then will help, but when you are putting 3k miles per month on your car, it's better to just block the stupid thing off. 2nd gens didn't even get the EGR system (with a few exceptions), the head is blocked off from the factory.
Sure, real-time performance gains are nil. But compare my internals now (80k+ miles since the last tear-down) with a stock 1st gen engine with the same mileage. Bet I can still see "Dodge" stamped on the tops of the pistons, just like when they were new.

I have to run premium fuel also and are not worried about a few pennies. I forgot about all the black goo that comes from that damn egr. I remember cleaning the hell out of my intake and head to get all that shit out at 80k when I done my gaskets.
Also you get some shit in it from the breather hose from the valve cover to the intake tube.Mainly oil....I hated that and made a catcher that catches all my oil before
it can be sucked up by the intake.This helped alot in the keeping clean business.
But Id like to block off the egr valve too....
Radar : Did you buy your block off kit or did you fab your own...Id like to know what all needs to be done, Or do I just simply have to make the plates and bolt them in place with a gasket.I hope its that easy LOL......Thanks

HOLY CRAP!!!! thats where that black goo comes from!!! I have that crap all over the inside of my intake! I found it when i swapped throttle bodies. How do you clean it out? I've been adding fuel additives (Chevron Techron, Kano Kreen) to try and clean the valves and combustion chambers and i was considering pulling the intake to clean it (and port it while i have it out). Any bright ideas on a good way to clean it? Like i said on another thread, a local garage has a new machine that hooks on cleans all the inner surfaces of the engine to like new, but it costs $105 to have it done. Advice would be GREATLY appreciated.
Man, I wish i wouldve known that was the cause of that crap when i replaced my bad EGR three months ago!!!! Talk about kicking yourself. where to the sensor wires go if you remove it with the mopar pcm?

Carb cleaner, rags, q-tips, and some scrubbing will get everything pretty clean. I've never used any type of fuel or oil additive. My dad is a total nut... I've watched him put a garden hose in the intake to "steam clean" the engine... very scary to watch... everything from a '67 Mustang to a Jag XJ12 to his current Focus. Never hydrolocked an engine, never busted a piston, nothing.
The hose from the valve cover to the intake mani is the PCV system. On my '95 SOHC, there's already a catch can designed into it, so I don't get anything from there. Everyone else would have to use an aftermarket deal, pretty sure Vitor sells them on his site (www.neongoodies.net), or you could design and build your own.
I got my original block off kit from Vitor, back before the Mopar PCM (EGR went bad at 140k miles or so). His kit came with a resistor to trick the PCM, worked most of the time, but the code popped up every now and then until I got the Mopar PCM. When I switched over from the aluminum intake manifold to the plastic, I just made my own with spare bits of plastic from my broken airdam and some RTV.
Rather than using fuel additives to clean, try the Mopar CCC. There's another brand out there (seafoam?) that a lot of people have had great luck with. Just remember that you'll need to change your oil immediately afterwards with either product...

Whats "Mopar CCC"? I've never heard of it before. I sprayed some carb cleaner in through my TB today with the engine running to suck it though the intake and it seemed to help a little, but not much. It doesnt seem to dissolve the carbon very fast so i doubt it really took much out. Is there any good way to clean it without pulling the intake?
There isnt a sensor that monitors where the exhaust gases from the EGR actually go is there? Could i fab something up to dumb the egr gasses say down under the car and just plug the pipe running to the intake to maintain vacuum? I know thats bad for the environment but whats good for the environment is bad for my car LOL. Or would it be better just to buy the block off plates and resistor chip? I suppose i could sway the $$ for that.
What is that oily line even for anyway? (the one from the valve cover that dumps oil in your intake) can it just be plugged or will that mess something up? would say an inline fuel filter help keep some of the oil out? I just dont want to have to clean my intake again. thanks for the help.

Mopar CCC is Mopar Carb/Choke/Cleaner.
If you look at my gallery pics you would see two intake set ups that I have run. The warm air intake like you are going to pay money for are no better than the APC cone filter I fitted to my STOCK dohc intake tube, I removed the whole factory set up Air filter box and all was removed. I used some
other rubber tube to build it up to fit the APC cone filter. It rubbed the heat sheild underneath the hood. I thought it sounded agressive but that was all.
The filter got dirty QUICK and if you sit in traffic for long periods of time I could see it getting heat damage too.( the filter that is). Its not a good set up and it's just like the cheap ass one your looking at.
The cheap poor guy cant afford to be lazy,,,,make your own. I ended up doing alot to my intake and shit after all was done the battery was in the trunk,the battery box came out but went back in ( just as a smaller peice)
( I need to get a pic of this trick I did it today and mounted my fuse box
back in it's place. You can look at the pics of the 3 inch aluminum tube I used
as the intake. Its not hard but it is a pain in the arse.
I may be wrong but that hose is just a breather hose I made an oil catcher to stop the oil from getting in.... A 5 inch pvc 2 caps and a couple screw in fittings drill tap and whalla.Thats really easy to do and it works. Let me know if you want more info on it.Or any of the mods Ive done BY MY CHEAP SELF.LOLlater

Are there two breather lines from the valve cover or just one? I know there is one on the right that dumps in before the TB, but there also appears to be one on the left side of the valve cover that dumps directly into the intake between cylinders 3 and 4. dodgeneonACR98, how did you secure the lines to the catch can? and do you have a way to take it off and clean it out every once in a while? Thanks for the advice.
BTW, why does the oil need to be changed after using Mopar CCC? I ask this because i just spent $30 on Castrol Syntec and a decent filter. would i at least be able to reuse the filter?

I dont know why that is with the Mopar CCC. It may seep into the oil pan somehow.
Im as baffled at that as you.
I didn't glue the caps on, that way I could twist em off and dump it out once in a while.I used a couple of coolant hose fittings to connect the hoses. One side is ribbed for a rubber hose and the other side is threaded. Screw the treaded side into the canister that you drilled and tapped and connect the hoses.I used a soft hose and zip tied the hose to the fittings for a better fit. HINT: find the place you want to mount it
and mark where your two holes will need to be drilled to keep the hose from bending.
And the holes need to be on both ends A top and A bottom hole. The bottom hole being about 2 1/2 inches from the actuall bottom of the canister, that top one being as far up on the canister as you can get I think my canister tube was 6 inches long.
The oil will run into the canister thru the bottom hose from the valve cover, then it will run down the canister to the bottom and Only the air will be pulled thru the top hose. I need to get a pic of it too. And I also have a better pic of my new air intake which is about to become even more new.I need to post it for ya.
Good luck.

Mopar CCC is "Combustion Chamber Cleaner" and only available at the dealer. Very strong solvents, and it will leak past the piston seals into your oil and greatly reduce the viscosity. Smokes like a sonofagun as well, your neighbors will think you've finally decided to just light the car on fire...

Is there a difference on the EGR valve for automatic and manual transmission?
rice_eater
10-28-2005, 04:47 PM
No... at least not on the first gen neons... i wouldnt think there would be on a second gen either. in fact i believe they are even the same from the SOHC to the DOHC. someone please correct me if i'm wrong.

Very few 2nd gens have and EGR, if any. I keep seeing the option when I search for parts at www.car-parts.com, but I've never actually ween a 2nd gen with one, even in California...
For the 1st gens, the valves are all the same, but the piping is different.
