Write Up: LML EGR Delete

When doing the EGR delete you will either have to modify your stock up pipe (cut and weld), or buy a new up pipe (sold separately).

If you are installing an exhaust at the same time then this will be much easier. Installing a new down pipe is also a good idea while the old one is out.

Image


Image


Step 1: Remove passenger side inner fender well. Turning the wheels to the left will allow more room for the install.
Image


Step 2: Disconnect exhaust somewhere near the middle. This will allow you to slide the front pipe back enough for the down pipe to come out. If you are installing a new exhaust system, remove it completely.


Step 3: To remove the front pipe, disconnect the V band clamp connecting it to the down pipe.
Image


Step 4: working from the engine bay. Remove the plastic "6.6" intake resonator. 3 bolts hold this in place.
Image


Step 5: Remove the air intake elbow with flat head screw driver.
Image



Step 6: Remove turbo heat shield. 3 bolts hold this piece on. Reinstallation is optional.
Image



Step 7: Remove the silver "S pipe". 9 bolts hold this in place. Disconnect all sensors/plugs. Twist lock ring and pull out the "s pipe".
Image

Image

Image


Step 8: Remove the EGR hot pipe. 4 bolts hold this on.
Image


Step 9: Remove turbo inlet pipe and PCV connection on back.
Image

Image



Step 10: Remove the down pipe. First, loosen the v-band clamp on the turbo side. The down pipe may still feel tight. Take a flat head and pry around the clamp. Remove the 3 sensors on the down pipe.

Step 11: Working from the wheel well, remove the down pipe bolt from the tab on the up pipe. Remove down pipe.

Image


Step 12: Remove up pipe riser heat shield. 2 bolts hold this on.
Image


Step 13: Removing the Up Pipe. This is the hardest part of the delete, so make sure you have a good breaker bar and impact sockets. You will need a 12mm 12 point socket to remove the 9 bolts that hold the factory up pipe in place.

I've high lighted the 3 areas where the bolts are. Each section has 3 bolts holding the up pipe in place. Imagine the down pipe and riser heat shield removed. The bolts are behind those...
Image


Step 14: Start by removing the 3 bolts on the exhaust manifold. Section 1. Keep gasket.
Image


Step 15: Next, remove the 3 bolts that connect the riser to the EGR. These can be accessed from underneath. Section 2. The gasket and bolts will not be re used.

Step 16: The last 3 are the hardest to remove (section 3). You won't be able to see much so most of it will be by feel. You'll notice a metal coolant line in front of one of the bolts...the hose will have to be loosened and pushed aside to access the bolt. Loosen the one bolt and push to the side.
Image


Step 17: Remove all 3 bolts from section 3. Unplug the sensor from the riser section. Remove the up pipe.
Image


Step 18: If you bought a new up pipe or are using a lb7 pipe then skip this step. Cut the riser section off the up pipe. Using a piece of metal weld the hole shut.

the pictures are still showing up for me..and I asked a few friends and everyone can see them on the AutoGuide app. not sure what's going for yall. I posted this thread along ti,e ago and photo bucket has changed their policy..it now costs $400 to post pictures on a 3rd party site. so dumb. if I ever get some free time I will re post the pics
 
#124 ·
Strange for sure.

Not sure how photobucket works but is there a way you can put those photos in an album in photobucket and just share the album link on the forum?

Does anyone have a picture of where the longer replacement coolant line goes? I know one end goes on the small nipple off of the black rail. But the longer end is puzzling me.

I'm working on getting the pictures back up...looks like I'm going to have to re upload them all to a free site and then re embed them on the forum...i went ahead and fixed one just as a test to see if the way I was doing it was going to work....(step 14)...id rather fix all of them like that so they are in order. I think people would get confused if they were just in a giant folder and you had to search around. I'll work on it some more later.

I haven't been very active on the forum in quite awhile but I plan on getting back into it!

I would love to see the pics as I plan on tackling this job soon. Parts waiting me in the box.....

if using an aftermarket up pipe with the delete kit does this eliminate installing the egr cooler or does that still need to be installed?

Sorry guys...but the pics are lost. I can't access them unless I pay photo bucket $400. In was able to find 3 pictures on my old camera but that was it. The next time I do a delete I will take pictures and post them.

Dirtymaxxx03, any way to make the pictures so a guy can see them? Downloaded the AutoGuide app and they still won’t show up.

The best thing to do is to upload pictures to this website. Then as long as duramaxforum is up the pictures will be too. To upload pictures:

1. Start a reply and scroll to the bottom of the editing window. On the left you will find "manage attachments". Click on it.

2. In the window that opens click on "choose file".

3. A window explorer like window will open. Find the files you want to upload. Click on the first one.

4. Click on "open". The windows explorer window will close and you will be back in the manage attachments window.

5. Click on "upload". It will take a few seconds but soon the file will be uploaded to Duramaxforum.com and it will be available as a link at the bottom of the post you are writing. That's not exactly what you want though.

6. To put the picture (or other file) into the body of the text click on the link in the manage attachments window. A new window will open with the picture in it.

7. Copy the link to the clipboard by highlighting it, right clicking on it and clicking on "copy".

8. Click in your text where you want the picture to be. I usually put a couple of blank lines before and after each picture but you don't have to.

9. In the edit bar at the top of the window you are typing the message in click on the icon that looks like a post card. I think it is actually supposed to be a picture of a mountain with the sun above the mountains but to me it looks more like a post card with a stamp.

10. A new window will open that says, "Please enter the URL of your image:". Type ctrl/v or right click on the box and click on paste. The address of the picture will be entered into the box. Click on OK and the picture URL will be entered into the text box where the cursor is. The forum software is smart enough to know that you don't just want the link. You want the picture to display there and that is what it does. If you want to find the link you can click on the picture to get it.

It's just that easy, ha ha ha ha.

To upload the next picture go back to step 2 and repeat the process. You can shortcut the process a little by uploading each picture you want by repeating steps 2, 3 and 4 before uploading them as a batch in step 5. Or you could do 2, 3, 4 and 5 repeatedly until all of your files are uploaded. I haven't found a good way to shortcut steps 6-10 exactly but I find it less confusing to do step 6 on each picture at one time and then move on to 7-10.

This will give you the pictures in the text where you want them but you will have a bunch of links at the bottom of the post. At this point you can go back to the "manage attachments" window and remove each attachment. The pictures will still be on duramaxforum.com and will still display in the message but the links at the bottom of the post will be gone.

This whole process has gone pretty smooth until I got to the last bolt on the up pipe, the one that's behind the coolant line. I've been messing with this thing for two hours. I pulled the bolt from the coolant line clamp but that doesn't really help. I don't even know why the clamp is there because there's nowhere for that line to go. I can't push it in any direction. The top of the hose where it switches over to rubber will move 1/2" or so in any direction but that's no help. Damn that coolant line! Couldn't be more in the way. Any other suggestions?

Has anyone installed a blocker plate on the on the Y from the factory up pipe where the EGR cooler use to be and had the bellows below the elbow blow out and create a boost leak?
