Ok some picture of the routing... found a diagram, but it was so small it was near impossible to read, so I made some enhancements Here is a picture of the hoses on the truck. I have given the picture the same color treatment that I plan to do on the truck itself. I did it using the diagram for reference. Hopefully someone can look at their own rig and verify placement of all the lines in my pics to be sure I got it right. The one that I'm not sure of is the lines going to red plastic valve. Based on the diagram... it appears that the center line green (the one between the lump and the other line) is the line that goes directly to the port marked "E" on the throttle body. The white on the outside is the one that goes to the "T" fitting on the line coming off the EGR port itself. Colted... you wondered if your red thing was inline incorrectly. This should provide the answer... barring that I have everything noted correctly! Can anyone with a good running sport without a CEL for the EGR system verify the routing???

so if I wanted to clean the EGR port.... which one is it and can it be cleaned on the truck? Shop supposedly cleaned it a year ago, but.... seeing as how I've never had the intake off myself... I can't picture it in my head I bet its not this port... it looks too easy? center of pic to the left... I'm betting its this one... bottom left... might have to get creative with a hanger... Based on the pic of my Sport I took this AM... it appears the EGR intake port is the one in the top picture, so I should be able to clean the port pretty easy. So is this the port which would build up with carbon?

I believe the port in the second photo is related to the EGR as well.

Maybe the 2nd one is the one that runs to the exhaust?

Wow! Red, I owe you big time!!!!.....thanks for taking the time on getting that elaborate diagram and picture with excellent color/routings, so the center nipple of that egr modulator goes to port E of the plenum and the outer nipple goes back to that T-joint w/c leads to both EGR valave & control solenoid.....I'll check mine this saturday and provide you pictures as well, hopefully someone with a good working and non-P0401 SES compliant monty can also chime in, LOL!
Just got the Seafoam I ordered from the jungle today and will also clean those EGR intake port/s as well.....heard a bad PCV valve can also cause the dreaded P0401?

From this thread: msport97.proboards.com/thread/8162/p0403-valve-solenoid-pictoral-reference?page=1wrench What fault code is present, if its 403 then you have a circuit malfunction check the wiring. you can manually check the egr function by pinching the yellow striped vac. hose leading to the throttle body with engine idling this will cause the EGR valve to open if it does then the valve and vac. system is good. You are looking for a ground and 12v at the connector with engine running. you can check the solenoid function by supplying it with 12v and ground and listen for a click. I think you can tell if the valve is bad by pinching one of the vacuum tubes running to it while the engine is idling.. it will kill the engine. Anyway, from an old Buggzyy post regarding EGR valves: Make sure the 2 hoses that connect to the throttle body are on the correct port. You should be able to pinch the yellow hose and the EGR should apply fully and stall the engine. Most common failure or problems are the vac. lines installed backward or the solenoid is faulty. I verified my routing is like the pics i posted above. Fault codes still have not self cleared after 100 miles, so i assume something is still messed up and keeping code on. So to determine what... i figure a code clearing as in order to see what is currently tripping light. I didconnected the battery. Then I followed these recommendations. Pinched the yellow line and the sport slowly started to run worse... got almost to the stall point and recovered. EGR malfunctioning? It was replaced at 225,000 miles with new. About 25,000 miles ago... NAPA version. When researching I read that you can depress the diaphragm in an egr and then cap the line with your finger. If the diaphragm stays up when your finger blocks the hole the diaphragm is good and valve should be fine. Will this test help verify function on ours? So I guess I will remove the egr. Clean it and check the egr line to plenum for crud. I will replace the pcv line and other vacation lines on the top of the plenum in case they are bad or blocked. PCV is new & Line was flushed with seafoam....

OK... so I started the rig up this AM. That dang intermittent clattering was happening. We let the beast warm up to almost operating temps and the noise did not calm down. it almost seemed worse then normal. I keep fearing its the timing belt tensioner. The fact that it did not calm down worried me enough that I decided the civic with its slipping manual was a safer choice. I don't want to risk the timing belt flying off and destroying the motor. The noise was near impossible to isolate. In the front it sounds like its at the front. Stand on either side and it sounds like it on corresponding side. I have heard the NORMAL lift tick noise and this is way louder and more clattered sounding. I have had the bottom end go out in other cars and it sounds like rocks in the dryer. This is NOT that sound either. It reminds me of sticking something in a fan and having the blades hit the object repeatedly at high speed. Its near identical to the sound the sport was making when the tensioner was rubbing thru the timing cover. In the vids I posted the first go around someone said it sounded like the noise a bad tensioner makes. Hope that is all it is.
So I guess I will fire it up tomorrow. If the noise is still as bad I will have it towed to the shop. I just don't have the resources to tear this guy down myself. Not when we need it on the road ASAP. If it is the tensioner, that is on the shop for leaving its bolts loose. I told him I worried it needed to be replaced once we saw it was what was wearing thru the timing cover. He wanted to be cheap and let it ride. I told him I was worried about it. So he can tear it apart on his dime and replace on his dime. I'm quite sure sitting in the wrong position with tension on it and loose bolts then coming into contact with the cover... so much so that it wore a hole thru it, could have very well hurt the bearings in the tensioner.

There are lash adjusters in the valvetrain. I have been told to seriously consider doing them when/if I do my valve seals. And what you discribe is what I am told is a possibility if not done?

Hmmm.... well nothing on the valve train has been touched since I have had it at 225,000 miles. now at 254,441. So that is a possibility. Its one of those was gonna get to it, but not till we had some extra cash and not until the other car was A-ok. Needs a clutch. Oh and oil level is fine. This is very close to the sound.... this was the sport when the tensioner was wearing thru the timing cover. I don't know why I did not video this AM... DUH! Now it just a bit louder and was intermittent and would go away. Now it seems to not want to fade away... youtu.be/3TjLjnRFyDc?list=PL6i3r31NYdheAG2WhtELuMyz9JrijpvUByoutu.be/D8MZdwQcmdw?list=PL6i3r31NYdheAG2WhtELuMyz9JrijpvUB. . . . Check this out.... the noise he gets is similar to what I'm hearing... 4:30 mark www.youtube.com/watch?v=tAxiFJ2rHBEAnd a Mitsu 4g63 motor timing belt tensioner that was bad... www.youtube.com/watch?v=gEt0piYkfLAOk I will video mine tonight to compare the noise to these. Again... if its the tensioner... its on the shop! . . . . . Ok since this is related back to my clatter issue versus the CELS.... I'm going to be posting about it here in my other thread regarding when the noise first occurred. msport97.proboards.com/thread/10936/growing-issues-sport-clattering-noise?page=1&scrollTo=62546

hey Red, is the one with the colors a pic of your actual engine?.......the center nipple hose from the egr modulator was consistent with mine, it goes to the E port.....but noticed that bigger hose that is connected to another valve (not sure the name is) next to the egr solenoid valve, yours was going back to metal tubing that goes downward to the engine driver's side, mine goes back to the top nipple of the plenum.....I never messed with that and hope somebody can check & chime in.....do you also know what that big circular valve on top is?

View AttachmentView AttachmentThe other solenoid on the bracket with the egr solenoid is the for the Evap. Think mine is routed the same as Colten mentions. Red circle is the egr valve and the green is for the cruise control.

View AttachmentView AttachmentYes that was my actual motor. Took pic and printed at work. Colored and scanned back into digital version. Let me look at the other thicker one... I had planned to replace those hoses next, but the Sport had other plans. Hmmmm based on my pic... ours is connected in opposite. Mine appear to have been replaced before me... PO... there was a jagged edge on the hose. If i go by the diagram i found and posted... maybe the purge control solenoid is what the 2 med hoses are connected to? Would that be the same thing as evap solenoid Jkdv8?? mounted on the same bracket as the egr solenoid?? Funny our cruise controls are mounted in different locations. That and my egr lines have sections of hard metal attached to the plenum. Your 2 appear to be one long hose from throttle body to the red valve and egr solenoid.
