05 Duramax lly knocking/tapping noise diagnostic and cold start.

compression test leads me to a slightly unexpected result. looks like we need a engine.

[@edwarddavis507]

Nice simple diagnosis EZ. I can’t wait to see what you do. Since this is a duramax diesel it would be an interesting rebuild. But all decisions come down to cost and what makes the most sense.

[@N1RKW]

Bummer about the engine issues! Much as I would love to watch you do a rebuild, I know that you will do what is most practical and cost effective (part of why I enjoy your channel so much!). I'm glad you were able to help your friend out with this situation.

[@buster7520able]

Enjoying your videos, can’t wait to see your next update on the truck.

[@Bruningable]

Another very interesting video! Looking forward to part two!

[@stevewoodbridge9250]

Dealer shops (doesn't matter if it is Ford, Chev or Dodge) have "Technicians" not Mechanics. They are not problem solvers nor does the shop pay them to be. If they can't plug it into a computer to be told what the problem is and what needs to be replaced forget it. That is why once my vehicle is off warranty I will go to a private shop where you find "Mechanics" who like yourself can problem solve. Love your channel and thank you for your time and effort that you put into every episode. Happy New Year and all the best for 2022.

[@Ashroyer86]

I think you got that backwards. Technicians actually should know how to diagnose. Mechanics are a dime a dozen.

[@wesleybrabant3595]

Great video. I'm looking forward to seeing how this turns out . I hope you take us along for the ride.

You just can't find to many friends like you, you are definitely one of God angel, I have to catch up on your other rebuild engine video's you created. you definitely a better KZbin creator and deserve a way lot more subscribers for your channel. but hey, that Peterbilt tuned me in to your channel, not a truck driver but I love me some Pete's and KW'S.

Truck looks in great shape. I had a 04.5 lly in my 2500hd. Loved it way more than my 2016 duramax lml. Put a banks power pack on it when I first got her. Retired her at 310,000, it's now are shop truck and still out pulls my new truck. I'd rebuild it in a heart beat. Had a lot of problems with my newer truck.

[@daviduruqi5507]

I do follow your channels and you come up with some great great ideas very easy to fix Keep it up brother

[@w056007568]

From what you said I'm absolutely sure you are correct in your thinking.That outfit clearly did not want to even investigate what was wrong so they pitched an appalling price to look and inspect to make the problem go away - goodness knows how much they would want to repair I cannot imagine!!

[@cjmyles279]

We'd all like a friend like you boss great content thanks from good Ole Wisconsin.

[@anthonygutierrez1038]

Nice video Ez. I’m definitely tuning in as I also own a lly with currently 415k mikes and still going strong..

[@johnhoffman8203]

Your troubleshooting techniques were spot on. Always do the easy things first like you did. With glow plugs cylinder compression is simple unlike my dodge with the grid heater, and then just change the oil which doesnt hurt anything. I dont know if the dealer would even do that to determine internal engine damage. Good video and smart advice, your gonna run out of things to fix.

[@mikeshultz1007]

I have worked on thousands of duramax engines when I worked for Gm as a master tech. 300 psi is the minimum compression for a lly duramax. The cheapest way to get that truck back on the road is to find a core engine that had a relatively minor failure, I bought a lbz a few months back that spun a rod bearing for $800 as a complete engine with turbo and injectors and it had 140k miles on it. I was trying to get a truck back on the road as cheaply as possible so I bought a used crankshaft and one connecting rod and I had the crank polished. I went ahead and did a 99 cent rebuild on the engine by dingle ball honing the cylinders and slapped new rings on the pistons. I was in a similar situation as yourself with that truck and I thought it would be better to start with a lower mile engine.

[@flinty2]

Great start to what will be some good videos I am sure!

[@McRocket]

3 thoughts. 1) I never thought of cutting open the oil filter. Brilliant! 2) this is just one reason ($5K!!!) why I NEVER, EVER go to a dealer for service unless it's under warranty. 3) you sound like a good friend to this guy. ☮

Got a engine on its way now. Not really looking like it's going to be a very fun job tho.....lol. thanks for watching 👍

[@Danbark601]

Good video! That's what I hate when people are busy they quote you an outrageous price instead of just saying they're too busy.

[@retiredtruckersgarage.7606]

nice truck i hope you decide to fix it,dealers can be bandits and i have a saying if the shop/garage is not busy dont use them as they tend to create jobs that dont want doing just to keep going,last time i heard a tapping like that it was a dropped valve on no1 cylinder on a 4.0l straight six rolls engine.

[@TedsGarage]

I always love engine builds, and given how successful your cheap build was on your 350, it'd be fun to see you go through and try to do similar on this one.

[@carlthor91]

It's all a matter of 'how much time' will he have to invest. If he's doing this his Pete and/or Mack will not be moving making him money. Although, with the price of used pickups the way they are, he might, and I mean might, make a profit. So, a long block, might be the way to go. Best wishes from the far North.

[@paulinebeckett2740]

cant wait to see part two, interesting video

[@philipbartruff3361]

Love the videos man. I can tell you this tho. Just get a long block or low mileage replacement. Building those gets expensive real quick. It’s much more cost effective to drop in a long block or used engine when you figure in the time for rebuilding it. That’s just my 2 cents.

[@madjack8031]

lol....back in the day my friends brother had a Datsun 240 with small block with side pipes.....u could hear it coming a mile away.....big fan of the new Mack Anthem design...to bad u can't get a Glider motor into one.....Cheers from north of the border!!!........

[@justinperry4587]

Might be a stretch EZ, but TruckMaster here on KZbin has teamed up with a diesel mechanic on his channel out of Wisconsin who rebuilds these engines consistently. You might look into a sponsorship for them or one closer to you for shop advertising based on your channel. Good luck and I’ll be watching for any future updates!

[@stovebolt448]

Well Ezera here we go again, no start light on Duramax, there is a squidgy line, when that goes out start the engine, there will be a pause as the computer checks everything out. I highly recommend a lift pump, Air Dog or Fast both are pretty much the same, we have a 2008 GMC Duramax and run a Air Dog, also whatever you decide on the driver's side fuel rail at the very back there is a plug with a spring on it, pull that sucker out and then just block the fuel rail off with a plug, long story not enough room here to explain, except it's a long trip towing a RV trailer from Bosie Idaho to Oregon at 35 miles a hour.

[@Anthony_T.]

Nice looking truck. Would be a good investment if you can get it done without going in the red cost wise

[@monteowens9459]

Enjoyed the video. GM shops are a disgrace sometimes, not like they used to be for sure. I think there are some really good mechanics too but GM and the dealerships themselves don’t want them to find out the root causes, especially if it’s going to take a little work. I think it’s all about numbers sometimes. Anyway, good diagnosis Ezrider. Take care and be safe on the road!

[@Ezrider359]

My point was it wouldn't have taken them much work to determine if he was looking at a major or minor mechanical issue so a guy can make a more informed decision. But seems how it wasn't as simple as plugging in there scan tool they didn't want to do it. That's pretty disracefull if you ask me.

[@christopherkraemer]

I’m the same with power service. I dump one bottle to every 50 gallons. I’ve never had a problem adding more, but I have had problems when not enough was added

[@seanmeyer6243]

[@vaughnhill3437]

Good luck on that duramax. I had a 2003 and i owned it from new for 8 months it spent more time at the dealership for pouring doesel.imto the crankcase from day one. The dealer couldnt figure it put amd they gave me the option to get another Duramax powered dually or a 6.0 gas amd i told them i wanted oit and they put me in a equally optioned gas powered 1 ton. I got very lucky because i had already bought 3 trucks from that dealer amd they wanted to keep me coming back. Will not ever own another one. I had a work truck with a duramax in it and it was junk too. Great power for a diesel but they just dont hold up

[@Ezrider359]

380k miles of commercial service before a major mechanical issue with the engine is pretty good in my book for a light duty diesel. iv had a few in the past without any major issues, all trucks of every brand have there own sets of problems. but i wouldn't say these "suck" its more pick your poison cause anything mechanical can and will eventually break.

[@Scotsborn1314]

I've read a lot of comments on here bashing dealerships and trashing people we don't even know. It would be interesting to me to find out exactly what the dealership told your friend. I feel, if they said that the bill would be $5k for them to open the engine and fix 'whatever', that is them giving him an estimate for a 'ballpark' price. They work on these things every day and get a feel for what the 'average' bill would be. Our society has, in my opinion, become quick to judge others and place blame where it may not be warrantied. I think a more disrespectful repair place, would know you friend is on the road, away from home, trying to make a living, so them 'jumping in', opening up his engine, running up a massive bill he was not expecting and disabling his truck in Idaho would be worse. Then he would be stuck paying hundreds of dollars to even get his truck back, making his decision much more difficult. Yes, your diagnosis found some seemingly 'terminal' evidence that there is an internal issue relatively quickly and you should be proud of yourself but, as you pointed out, it would not have changed your friends situation or the outcome.

[@cullenmiller8170]

Well, the first mistake he made was go to the dealership. Depending where in Idaho, but in the Boise area there is Smith Detroit. They are good people and honest. A friend of mine uses them and he owns a trucking business. They have saved him thousands of dollars multiple times. I don't know if you can get the oil pan out to look at the bottom end to help figuring out how bad the engine is?

[@ncut5547]

The driers side is easier to get the cover off than the passenger side I've worked on them a little bit and they are not the best but the engines are pretty good on the most part ...with that low compression I would think valve train or maybe rings but it dint smoke much so be interesting to see watt u find ..

[@briansims4365]

Will be a very nice truck when it's fixed EZ. What kind of work do u think a 250000 used motor might need? A rebuild will give u a little more peace of mind with the finish product. Good Luck EZ!

[@sajesearle379]

What a bloody rip off of the Chev Co I couldn't get over that it used to happen down here but the bought in tougher laws for the consumer and it has stop the real bastards in the motor industry. That is one of my favourite trucks you can't buy them here and that's got a pretty good body on it, anyway it will be interesting to see what your going to do but with all that metal floating around, it looks like a rebuild. Take care try and keep warm John

[@kwippl4207]

The LLY is a good engine and worth the rebuild, but it is not a cheap rebuild. I just did one a year ago. Good luck finding a low mileage used engine. Since it is pre-DEF so I would rebuild it. Keep in mind the lower end of the LLY is a little weak imo and you may want to look into beefing it up (the kits are there). Thank you for the video and the diagnosis. Where did you get the filter opener?

[@rickydavis5541]

I take the LLY over 6.0 ford diesel that need a rebuild all the time the Duramax parts go forever and aftermarket one are better built.

[@TheRoadhammer379]

Ezra, I don't believe the duramax has a wait to start light. I think just the little curly pigtail indicator, for glow plug, and it's only a momentary light.

[@robkittle1899]

I can tell you from experience that you are going to be well over 10K for a reputable reman. Because of the hardening on Duramax Cranks, if it is scored, it is trash, no field servicing. They are great trucks, but just not cheap! I had a work truck with an LB7 that we had to put a motor in 4 or 5 years ago. Almost 12K just for the long block, plus labor and misc. That was 1 day after getting it out of the shop for a 7500 head job, which was 2 weeks after a 5k injector job. Long story short Duramax fans, if your injectors start hazing, don't drive it another 10k miles!

[@Davidlabar4]

A good running relatively rust free cat eye duramax will bring 20-25k with 200-300k if the miles are less they bring even more. With what has already been done plus a new motor that dually will bring over $30k+

[@Ezrider359]

I don't see them sell for quite that much here miles are enough to scare a lot of people off. But repaired I'd guess it's worth 15 or so but I plan to keep it and replace my f350 with it

[@matthewhansen5008]

They gave him the $5000 dollar price so that he would take it on down the road. You may have mentioned it earlier but is your Ford power stroke still up and running?

I'd say one way or another, you're pulling the motor. yank it out, crack it open and then decide what your going to do. It's not like you need it on the road tomorrow. You know as well as I do, that you'll end up rebuilding it, only 'cause you'll want to do it right.

RV hauling is a fools errand. I did that for a year and ended up going under. You wear out the truck faster than you can make a extra buck.

Seems like a nice truck otherwise. Me personally, I would go with a long block from a reputable rebuilder. Just my opinion

[@timmay2k]

That’s how shops rob us truckers. The $5,000 was basically an F off deal. There loss. My guess u can probably rebuild that truck put a new turbo on it radiator intercooler and oil cooler on it for under $10,000. And flip it for $25,000-$30,000
