How To: EGR Delete on LML Duramax STEP BY STEP

FULL DELETE KIT HERE shrsl.com/4ke0v
SHOP MERCH HERE darkirondiesel...
In this video I will be going over the procedure to delete the EGR on a LML Duramax. The truck in the video is a 2016 Denali HD but the procedure will be the same for any LML Duramax. The kit I am using is a Deviant Race Parts EGR delete as well as a 3" Flo~Pro downpipe. A fairly common problem when doing this delete is snapping one of the bolts on the turbo which happened to me, so I also go over the procedure to remove the turbo so you can drill and tap the hole if you break a bolt.
To do the EGR delete you must also delete the DPF and tune the truck to run without emissions.
**If it is illegal in your area to drive on public roads with a deleted truck then don't do this! This is for off-road use only!*

Thank you so much for this video. I used this one and your DPF delete video deleting my 2012 this weekend. I got lucky and after pulling the heat shield my down pipe came right out like nothin. Had one hell of a time getting the bolts outta the turbo but managed not breaking any. Thanks again for what you do on here man.

[@taltonbane]

Didn't do mine. Staying stock but have done a few. Having host I lift the cab. Actually saves time and easier getting to everything

[@taltonbane]

Just to clearafly I worked as a mechanic in the oil fields in Canada when I helped do this delete which I understand isn't illegal there. Seen a couple of mud boxing diesels that had the whole delete and programs done but wasn't much left ot the cabs .easy to get to most everything which is good because of the broken crankshaft or piston breaks.

[@rickpoage9355]

I fought with my downpipe for way too long, I learned words that soap won't fix. With no luck I spent 10 minutes removing cab bolts on passenger side and jacked up cab, down pipe fell out. Don't cuss, don't bleed, don't waste time. Jack the cab before it jacks you!

How did you get that lower passenger side nut off the passenger side up pipe? Literally only thing holding me back right now. I have sprayed so much kroil the past week.

[@freetoride003]

just a quick tip for future down and up pipe removing! remove the two cross member nuts for the transmission and loosen the two engine mount bolts then jack up the rear at the transfer case. it will create a few more inches of space between the firewall and the engine and all three will be easier to remove and save you alot of cursing and blood.

[@mohamedabdelsamie3128]

Guys one of the mistakes is to loosen the 11mm nut on the down pipe clamp before getting both shields off , start with the small heat shield it will come seay from the side then the bigger one u have to pull it from behind too and wiggle it a little bit but it comes out easy 2, after that loosen the 11mm nut for the down pipe turbo clamp and it slides easy down

I ordered the tuner and gave the info for mods I was planning to go ( I have all parts ) EGR complete Dpf delete Sensors disconnected Cold air intake installed Fass lift pump Not installed yet 5 in flow pro straight pipe not installed i Down pipes Not installed Up pipes Not installed EFI live tuner arrived I installed the switch and flashed Seems to run fine , no engine light But my driver window doesn’t work Back up camera doesn’t work Air conditioning compressor still not engaging Bummed out the screws for continuing any more work until I get this right but I’m not driving the truck. Put a snap on scanner on it and it had no codes.

[@darkirondiesel]

Never had those issues before personally, but YOU CANT RUN A DELETE TUNE WITHOUT REMOVING FACTORY EXHAUST! The delete tune deactivates all the regen/burn process, so your exhaust is going to plug up and you can seriously damage your engine!

The clamp that you used to fasten down the hose… do or have you ever had problems with the hose blowing off due to pressure? Is one clamp enough to fasten down the hose ???

[@fieldtrailer]

It helped me. It helped me decide not to try this. Ridiculous. When I deleted my LML, instructions included disconnecting 3 connections for egr delete. Do you know what the difference is between that and what you did ( besides physically removing egr)?

[@darkirondiesel]

Haha ya they aren’t fun. When you delete the dpf and install a delete tune on a truck you have to unplug the throttle valve and the 2 egr plugs on an LML. Basically it deactivates the egr system. The valves should remain shut therefor not letting exhaust back into the engine. Guys will physically remove the egr system for a few reasons. One is for peace of mind, if you remove the egr system and block it all off then you KNOW 100% that there will be no exhaust going back into the engine. Second reason is that sometimes the egr coolers crack so you start burning coolant or pressuring up your coolant system. And the third is just for looks, it really cleans an engine up when you remove it.

[@mikemorris4958]

You just did an "electrical" (or virtual) delete. He did a physical delete in this video. Basically you just disabled the components, and he removed them.
