Great Video! If i could ask a question i have a 2005 Chevy Silverado 2500HD Duramax Diesel LLY. Recently i went through hell and was able to get my FICM rebuilt because it was Leaking massive fuel and running intermittently rough. They rebuilt my FICM and replaced a fuel line. Seemed to run good for a while but then at a stop the rough idling came back and pulling wanting to drive forward with my foot on the brake. I have 106k miles on the truck and never had my EGR cleaned or looked at. Also on the freeway after an hour or so of driving occasional loud pinging type diesel noise would happen and go away. On throttle and driving seems normal but maybe less MPG fuel economy i am noticing. Thanks again for the video!
That intake and EGR valve was clean! I'm curious about how many miles it had on it. I have the same LLY Duramax and have been concerned of late about the EGR system getting plugged up. What is your personal experience regarding these intakes getting plugged up? Thanks in advance for any input!!
I’ve got a code p0404 and p0405 p0299 first two are for egr and the third one is for underboost. Figured the egr would be the main issue do you know of any of those codes point to a bad egr or just check the power to it and give it a good cleaning. It’s a 2005 2500.
The P0405 indicates an electrical issue either in the wiring or the valve itself. The llys have wiring harness problems so i would do a thorough inspection of the wiring before replacing the valve.
Hi Sir. Love your videos. I have 2005' Duramax LLY. Losing 1/2 gallon on coolant every 3 days. Truck runs constant 7 hours daily. 467,890 miles been perfect. Dye test and no coolant leaks anywhere. Never trys to run hot. Question is my top hose is a little hard in morning at times and coolant system seems to build pressure. Could the egr cooler create same symptoms of blown head gasket. Great content sir.
The Egr cooler can cause those symptoms, Before I ever condemn headgaskets I always pull the egr cooler and inspect first. I have only seen a failed egr cooler on a duramax once. Its more than likely you have blown head gasket/s unfortunately. Its a very common problem on the lly's with higher mileage. I have a customer with around 700k miles on a lb7 duramax and has the same issue with coolant consumption, I recommended to him to just keep topping the coolant off. As much as i think the duramax is a superior engine i wont do head gaskets on a truck with more than 300k.
If I was delete my egr on my lbz duramax I wouldn’t have to worry about swapping the value anymore?? Or do I have too. I’m losing air flow, underboost on turbo & exhaust gas recirculation?? Im new the diesel community. Point me to right direction please 🙏🏼
If you delete You shouldn't have to worry but you may have to physically remove the egr system because if the valve is stuck open if your deleted it may open up still. But be aware deleting is illegal in all 50 states.
hey pal...I found my cooler has an external leak last night right after your shop closed for the night,where in the world can I find a new one?I stayed up all night looking and they are all for 01 and up,mine is 03 lb7,only one I found is 1000 dollars.
Hey would you mind answering some Q's? Friend took his 2004 66 2500 HD to get a diagnostic because the truck has a very ugly pulsing idle so they told him that the fuel pressure regulator was bad and needed to be replaced. Today I was tasked to do this job, however, I noticed (forgive me I dont know the parts too well) the "EGR valve cover" top portion as well as the EGR valve itself, was completely clogged with oil residue. also the aluminum tube end portion of that cover had diesel puddling on the inner walls.... Can the EGRvalve and top cover be cleaned and replaced? Also when removing said "EGR valve cover" the aluminum gaskets had a bit of silicone residue left behind. is silicone needed in addition to said gaskets?? please halp lol. Were just two broke dudes trying to fix stuuf.
The fuel pressure regulator will cause surging at idle , it’s a common problem on the early Duramax’s. You can clean the egr valve out with some brake clean and a screw driver you just don’t want to get the motor wet on the end. Make sure when your done the valve is closed all the way. Some people put silicone on those gaskets, if you buy new gaskets it’s not needed just make sure the mating surface is clean.
@@drewsshoplife wow thanks. Feels good getting the feedback. I will be cleaning it sometime this week. It is a work truck so most of the time they are idling or driving short distances ha.. And his daughters use the truck which I do not encourage cuz they ruin every car they have ever had.
I use old style Easy Off oven cleaner, be careful, it'll damage paint, etch shiny aluminum. I use it cleaning cooler cores in EGR on Semi trucks, only snake oil that I found works.
Your name defiantly sounds familiar , the cooler looked fine in this case. The egr system is always dirty , Most of the time the egr coolers look fine (even with higher mileage), only when there is a lack of egr flow or excessive idling also when they rupture thats when they plug up. Sounds good ill be here
The Egr Valve Failing Cause Egr Related Codes, Mass Air Flow Sensor Codes And Turbocharger Boost Codes. It Can Cause Smoking And Loss Of Power. Just Depends On The Manner In Which The Valve Failed.
@@drewsshoplife I gota ask my truck is a 05 duramax and it will only start if u give it sumthin 2 help do u think it injectors bad or a bad cascade valve it looses pressure soon as u turn truck off
Good diesel mechanic! made it look easy

When changing that valve does the new one have to be calibrated or is it just plug and play?😊
Just plug and play, no calibration or learning procedure required

Also, what would cause such a dirty EGR valve and cover? Why so much gunk?

The egr system fills the intake system with soot. Idling the engine excessively causes the build up or driving the truck constantly short drives.

Does a clogged up egr valve cause black smoke out of ur exhaust?
f the valve hangs up it can cause a loss of power and smoke from the exhaust.
Can you share the part number on the gasket and how many I need I’m going to do it on my 04 lly thank you
For the lly this is the set you need :dmaxstore.com/products/?route=product/product&product_id=1027
