95 Honda VX owner

My mechanic showed me that the spring has weakened, so the EGR opens too easily. Anyone taken one apart to replace/add a spacer to the spring? That tremendous clamp makes it look like it should come apart, but it's not obvious how...

I have used the FSM troubleshooting procedures. Takes a lot less than 8" of vacuum to open this EGR; he had it opening and closing by simply sucking on the vacuum pipe.

I'm not getting an EGR error, fyi.
Question: Wide range of acceptable values at the ECU (EGRL) from the 'EGR VALVE LIFT SENSOR' ?

Anyone successfully taken one apart? Does the spring shoot across the room, or are there other 'gotchas' to look out for?

(Yes, the VX has an EGR; D15Z1 engine).

Any help/guidance greatly appreciated!

<p>@OG Wagon has a VX. I believe he's cleaned out his EGR before. You might want to PM him or maybe he'll pop up in this thread if he knows what's up with your issue.&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>

Why not just replace the EGR valve?

~$300 if I could find one: "discontinued" Not surprising, as they only made the VX '92-95

and who's to say I wouldn't get one with the same issue if I go used?

Why not scout junk yards for VX EGR valves? VXs are rare but might be worth a try.

Buy a used one and take it apart. Buy a used one and take it to your mechanic and him test the vacuum on the spring. You have options, exercise them.

<p>HX's also have an EGR valve. I don't know how similar the HX intake manifold is to the VX manifold, but you can find them cheap on ebay if you can't find another EGR valve maybe you can swap manifolds.&nbsp;</p>

Hold on, Mama Bird. Which 1992 4DR came with an EGR? That doesn't sound right.

Thats a listing he found of someone selling an egr. Either way someone must've done a d15z1 swap into an eg 4dr or the junkyard made a mistake in the listing.

I was tagged to come on in for input if I could, so here I am. I've read the OP's question and all replies. Some great info. here! Yes, Caoboy, I have cleaned out many an EGR, including the one on my VX. Unfortunately, my workings have merely consisted of removing the cover and spraying brake degreaser liberally to every nook and cranny that I could. Here is some input that I have:


1. OP, seems you are fairly proficient at testing these. Seems that a plausible option would be to purchase a used unit cheap and put it through the same psi/vacuum testing that you have put yours through, see if it lines up. Where did you get the 8psi figured/standard from?


2. www.car-part.com is a site that everyone should know of. Check it out, if you haven't already. You should be able to source a cheap VX EGR here. Fortunately, it should be cheap for anyone to ship you one. Ebay will likely be too expensive to make purchasing used worthwhile, considering (as you have mentioned) you could possibly get another "dud".


3. I didn't realize the springs on these could go weak. Actually, I've never heard this, in all of the EGR research I've done on Honda forums. Not to discredit your mechanic, but to be frank, I doubt that's even possible. Anyone else every experienced this? I mean, if it is, that may explain why many of us "clean" our EGR's and they still show no improvements.


4. Spring aside, there are some electronic elements to an EGR. Is the EGR more mechanical/manually run that it is electronically powered? Obviously, there are wires going into the unit. Is this from a sensor that solely READS the mechanics, or does it power a motor/actuator which serves a functional role in the mechanics? This is valuable to know, as it may not be the "spring" that's worn, but rather an actuator/motor inside the unit.


5. I'm near positive that if you could remove the spring, there would be a "Jesus!" moment. Sorry, crude humor, but down here in the south we call little guys like this "Jesus springs", because they shoot 100 mph across the room when you free them, and you say "Jesus!" haha. So, I always try to put my hands and the part into a little grocery bag when I'm trying to remove them. Not 360 degree protection, but about 270, ha!


6. Most 80's/90's Hondas have an EGR port/channel system within the intake manifold. Sometimes the plates are removable (such as in the case of most Accords). you just remove the plate, do your cleaning to the EGR pathways/lattice, and re-assemble. The VX, rather unfortunately, does not. I read some posts about others drilling out the holes to free up access to the EGR holes just before the injectors. Then, they sprayed in brake cleaner to attempt to clear the passages. I didn't do this, for a lot of reasons. For one, the IM has to be off of the car, or you risk getting metal shavings into the engine. Also, I didn't like the fact that it just freed up access to the holes and not the entire pathway. Then, when you are completed with this glorious demolition, you have to fill your holes up with a metal epoxy or similar. All that work for a half-butt job, IMHO.


I hope all of this helps in some way. Keep us updated. This thread is still very relevant to me, as I do still occasionally have a hunting idle, mostly during extremely warm outdoor temps (90 degrees plus). I wonder how much it has to do with my EGR and/or idle settings, and much more to do with the fact that the EGR ports within my IM (which I was unable to service, as per point #6 above) are all gunked up and need cleaning.


Thanks!
