One thing I forgot to mention was the piston rings. While the engine doesn't smoke or have any excessive blow-by, I am still considering swapping those. Maybe, I don't know yet. Also before you ask, these are chromed liners and cannot be honed!
You are at the point where it is easy to check the gaps & condition of the rings - its not like its a V16 5000Ib engine - lol. Check the cylinder that looked slightly different & make a guess from there. Its only going to cost you a little time.
I may be wrong, but as I remember when flex-hones first came out they were on about how great they were for chrome lined aircraft cylinders. Mostly known as ball hones now. It's been many years since I saw that brochure for flex hones, they may have been referencing newly chromed cylinders. Dang memory sucks when you get older!
The fact that thermostat has been removed and rad blocked suggests it was overheated so that makes the rings to lose tension and stick to the groves of the pistons so new rings and deglaze the cylinder bores would be the way to go
Engine looks good Matt. Feel for poor Charlie, one of our dogs has two hot spots at the moment, she’s on steroids and an antiseptic wash… I watch your adds, helps you get paid..🇦🇺🍺🍺
Matt, considering you`re no construction plant specialist, you do a pretty good job. Over 40 years doing this has taught me a huge amount in life working all over the UK and overseas, and working with some really good guys. If I could go back, i`d definitely do it all again. Enjoy. Regards, Dave, Cambridge UK
Thanks Matt, we always appreciate your videos. The video shots take us close to the action and we can easily see what you’re working on. You don’t profess to be an expert but you’re good at diagnosing and finding fixes. Keep them coming please! 😊
Hey Matt, it occurred to me that belting the sump with the hammer was probably the reason for breaking the baffle plate. Probably twisted as it released? Sometimes sh#t happens! I’ve watching since you dragged the dozer out of the forest, enjoying your stuff. From Nick, Isle of Man
Matt, it looks like the engine has many hours to go before it goes to the scrapyard. I always like your comments when you work on a project because you know how to analyze a situation. Blessings to you.
Your TH-cam had me hooked from the first time I watched. Just working out of your garage (barn) and doing wrenching that most of us "could" do but don't. Keep 'em coming.
Quallity. That's my one-word summation of your work and your videos. You may not technically be an expert, but you put more thought and effort in than most experts would!
Matt, you're doing a great job! Just a hint... get a old plastic milk crate, cut it to sit around the center bottom tube of your engine stand and then you can use a large drain pan sitting on top of it to collect everything when turning the engine over in the future. It makes life simple lol.
Matt, I had on old time heavy equipment mechanic give me this advice: he said to out a light coat of grease on the fitting before installing radiator hoses. They don't leak and are easy to uninstall and reinstall in the future. I have used this on cars and equipment and never had a problem. Just something to consider.
I really enjoy this Channel. I've been building and fabricating since 1967. Your approach to this engine is exactly what I would do given its condition and use. Great Job ...
Man. After all that work on the D4, I'd drive it to get groceries. As a Duramax owner, I'm cyrious about how Isuzu approached one of their other engine designs. Great channel, with great content from a regular guy. It's amazing how much we crave content that isn't biased or political. Keep bringing this content. Channels like this are what makes YT remain viable.
I really, really like your videos. Just to let you know, i watch every videos you put out, and if they were 4 hours long i would still enjoy every second! long! Remember that what YOU consider boring, probably is interesting for us who just watch and envy your knowledge😊 I also love seeing Charlie (Charly?) in your videos. I had one 37 years ago, that looked exactly like yours. Her name was Lady and she sure lived up to that name 😂❤ Thx again for all your postings, they are on my top 3 on TH-cam!
I am new to the channel and really enjoy how you approach the mechanicals and, really, the risk assessment of repairs. So many YT channels just do the very bare minimum to get something running. Drives me crazy. I appreciate the thought process of doing the 'right' amount of part replacements and overhaul work. I think, as mentioned below, I would do exactly as you have. No sense in tearing the block down completely if no signs of damage. Really, 9K hours is not that high. There are many examples of 14K to 20K engines out there. Take care of the maintenance and it will serve you for many more years. You know that, of course :).
After all is said and done, Make sure you check and Clean your fuel tank! Many folks forget that step and live to regret it! So, Please cut that off at the pass! Save you many headaches! Hope fully you can get into your tank without have to cut a access hole! Love you content(with or without ads). You post it and I will watch it! Great Job. You probably have read this before but, post more often (if you can)! See you on the next one!
You seem like a pretty modest guy to me. I enjoy your videos and the fact that you're doing things that I'd like to do if I were in your situation. You've got a lot of skills and you make great content. I don't begrudge you the revenue that should come from the adverts. Thanks from the UK.
Great watching you work, I am fascinated by engines but am scared to do a strip and rebuild myself! Don’t think I could get it back together properly🤦♂️. I content myself with being able to do service items etc and if I need some “heavy” engineering get someone in to do it. Pleasure as ever, keep at it I am keen to see the result of all your work 😀👋🇬🇧
Isuzu engines having a reputation for being really good and it shows how many applications they are in. My 2003 Silverado has an Isuzu engine in it. So does my 1990 Isuzu Trooper.
Agree. Isuzu makes fantastic diesels and did make great petrol/gasoline engines in the past. I had a Trooper with 2.6l petrol which ran 700,000ks and was still in spec, and then I got a Trooper with the 3.5l petrol V6 which was such a sweet engine - 160,000ks did the timing belt and 4 valve gaps were out by a tiny amount. Nothing went wrong with it, the brake pads even lasted to 160,000ks and the vehicle was the GM 4l30E which was as smooth as silk behind that engine.
Even the modern Isuzus I work on in large diesel generators are absolutely fantastic. I only deal with modern emissions work on them mostly. The EGR valves need cleaning along with the EGR coolers which is quick and painless. I love them
Me watching this knowing nothing about engines: This looks good right? Matt: "This looks pretty good" Me: Yeah i knew i was right Also Matt: "I have no idea what im doing" Love the videos man always a pleasure to watch
I really love watching this channel, I love your no nonsense approach to rebuilding something that needs attention. If things look ok as many things on this engine do, you opt to leave it alone. You mentioned in the comment section that you may replace the rings. I'm not sure just what I would do, you are replacing bearings, it wouldn't hurt to push the pistons out and have a real good look at the rings and go from there. 9100 hours is quite a few, maybe talk to sombody that knows what you are up against and see what they say. Keep up the awesome work, I learn a bunch by watching you. Jay from central Pa.
Your comment about don’t do what I do I’m not a professional, that is completely untrue. You have the proper outlook, the tools, and the knowledge to determine what that motor needs! As a mechanic who has built five different manufactures brand of engines from the ground up do you go about it exactly the way to person with common sense would attack this project…. Keep up the excellent work.
Great engine inspection. It was worth your time to see what condition it is in. It looks like the biggest problem was the missing thermostat and crappy fuel. I do not think that you will be using the machine every day so things are good. I admire your willingness to venture into the unknown and learn as your go. I hope that putting the engine back together goes well. I hope the rest of the machine does not need to much work other than hoses. Love the video and thanks for sharing it. I hope the dog heals fast.
Looks good Matt. If your in there replace the rear main seal as well. Waterpump is toast can hear it from the bearing noise. The craked oil pan is probably vibration from the broken motor mounts.
You and @JustaFewAcresFarm are fast becoming my two favorite TH-cam channels! Full of wisdom, ingenuity, skill and perseverance. Thanks for bringing us along!
Don’t sell yourself short Matt. Your technical abilities would leave me for dead Mate. Your ability to figure things out is incredible. Keep up the work Mate 👍👌
If the pistons are oil cooled be sure to check the check valve springs on the squirters. Sometimes the internal springs fail and allow oil out of the squirters during idle. This can cause you to see low oil pressure. I also reccomend that you check the cam for lift. If the engine ever sat for a long time, it can cause rust on the cam lobes which will cause them to wear out. I would check all of the oil pressure relief valves to be sure they are functioning correctly.
Matt, I headed straight out to my shed and had a look under my bench as I suspect at some stage the original owners of my home had a small bathroom out there, anyway long story short I took the plug cap out of the old faucets and installed new taps and valves and bugger me but it’s still all connected so plumbed my pressure washer and snap, hot water pressure washer, saved myself heaps as had been saving for one, wife very happy = happy wife, happy life. Learn something of everyone of your videos mate….lmao.
I fully agree on your assessment of the pistons, rods and liners…. But, this far down I would hone the cylinders and throw a set of rings at it. Cheap “what if” insurance. External parts are sometimes a pain, but at least you don’t have to yard the motor again.
Hi Matt , Good call, As you said the engine is not going to Daytona. Real good shape and this unit will give you years of service around the Farm . thanks. Will be back for more.
Really like your calm demeanor working through these projects and just running the numbers when how to take things apart when you don't have all the data. Also love the 1940s Firestone made by Plomb 1/2 ratchet. A bit of a vintage tool geek/collector so always notice things like that. Anyway keep up the awesome work and content.
I've done a lot of exhaust work being an exhaust business for 30 years your best bet actually is heated red-hot like you did and then shock it hard with cold water!! Spray it down with a spray bottle get it dead cold! And it'll just fly off of there now if it's a brass nut you got to be careful!! They may melt!! You are doing a super great job!! All the best from Surrey BC Canada
Hello Matt, all seals gaskets bearings you should change, when you have a chance to do that..... All other things are within specifications. or mathing them you can forget them(no need to replace or change them) but seals bearings gaskets you should change. Good luck! see you SOON (as you said) 😏✌
4cyl diesels tend to have bad harmonics and are usually balanced for their high idle speed. Its just a stress fracture in the pan. Keep up the wonderful work!
Just gotta add my 2cents here-- 10,000 hours?- consider at least some rings and a hone -?? just my opinion I like how well you check things and use your common sense on repairs - keep up the good work(missed the chrome liner info- sorry)
Something to think of. You might want to change the freeze plugs out since you have it torn down this far. It's better to be safe now then later if one fails and have to replace it in the machine.
Matt, a rusted bolt you can usually take a air hammer gun with a flat or dull bit and hit the bolts or nuts a little and it shocks them and breaks the rust loose for breaking them loose! Just something I’ve learned throughout the years! Up to you if you want to try it sometime!
You and about 3 other channels are the only reason I still use youtube. Not suprised they are removing those creator options. I will still watch your videos though, top notch content!
Thanks Matt, I appreciate the time you take to examine everything, your explanations as to why or why not do something, your attention to detail is much appreciated, it makes your channel a pleasure to watch. As always stay the course, you will end up with sweet track hoe, looking forward to seeing it in operation.
*- Matt, your "novice" experience, of getting into and through the tear-down, draws me right onto your stage as someone who has never done such a thing.* *- Good editing and good copy are to blame for all that...{roaring mirthfully irreverent laughter here}.* *- It may be slow or tedious for your many viewers who are real mechanics or maintenance experienced machinery owners, but I sure do value the my experience of your "1st time" forensic discovery process at a pace that works well for me.*
Your firewood video was amazing, that’s a lot of wood to handle, split and stack my friend! Good job Matt! I’m praying that this excavator is going to benefit you so much on your property projects my friend! You learn as you go butterflies nobody is perfect and I appreciate your efforts and you sharing everything with us! Using hot water isn’t like using boiling hot water Matt, it’s not going to harm the seals my friend! It’s not hot enough!
Wow it has been a while since the dozer was finished Love your work hope Charlie gets better soon, the Cone is sadly needed to protect her , until the next one stay safe 😁
I am impressed with your courage and your skills and knowledge even if you are learning from reading just for the project. I have always been the self taught type learning from manuals and such. I would be confident in your work and no sense spending money unnecessarily! 😊
Old school impact, sweet. The vent needs to be run down so it does not let the blow by fill the engine bay. Looks like warm water for cleaning the tank out too.
*- Matt, my vet proscribed antihistamine tablets to stop the hotspot itching issue for my old English Setter. They worked great...check to see if long use of antihistamines is damaging to the kidneys, etc.* *- Don't take them for yourself in an emergency...you will get dizzy and very loopy.* *- You might get away with cutting them in half, if you had to use them on yourself.*
Good move on not disassembling the fuel system...I've seen people do that and it's a bear to get it back together...plus yours isn't having any issues. Poor Charlie...the Cone of Shame! Hope she gets better soon :)
You made me so happy when you said you were just going to replace all those bearings. The way you were talking about them I was worried you were going to leave them. Great video as always Matt!
You sure scored a BUNCH of points with me by tapping the wrench with a hammer. I cringe every time I see someone putting their weight or a cheater pipe on a wrench to loosen a bolt or nut. I recently was called on to help a fellow put bearings in an old rusted 12ft disk harrow. He had a 5 ft cheater pipe and was struggling. I used the appropriate size box end wrench and wacked it a couple of time with a 2lb shop hammer and they came right loose. Too many bolts are broken by not using this method and while it doesn't work every time, it does more times that not. Matter of fact, I have had it loosen fasteners when an impact wrench wouldn't.
I always enjoy your video content. watching you work out problems is informative and makes me realize that I could have done what you do, perhaps better, perhaps worse, but it isn't a mystery. BTW I hope Charly's hot spot get better. She is a great looking dog.
Thanks for the hard work in producing and editing these videos, Matt, which are unspoiled by histrionic voices and wordy gush. I also appreciate your "If it ain't broke don't fix it" approach. Poor ole Puppers wearing, much to the loss of her personal dignity, an Elizabeth collar!
I have the same excavator. I had to get the fuel pump rebuilt, that was expensive. I would like to see you setup the engine speed sensor when you get there... I am getting a warning on it. Be very careful of your fuel tank... take it off and clean it super well! That has bit me bad. I saw on my other favorite channel, farmcraft, he had a ton of issues with that too on his new to him dozer.
The first hillbilly thing I saw Matt do: Put liquid that evaporates at temperature X on parts with temperature > X. Like when I tried to rust proof an exhaust with petroleum jelly.
even if not an expert, you are good at camerawork and talking to the camera usefully. The term 'dilettante' has some negative connotations, but it's not necessarily a bad thing to dabble in a lot of skillsets without committing to becoming an expert: it makes you versatile. and you seem to have worked around enough engines to know what you're looking at WRT wear and engine high operating hours. (it's impressive that this engine is still this fresh with 9000 hours on the ticker)
I am an engine builder . Race cars mostly. you do the new bearings like your saying with new rings and that motor with decent care will outlive you. Couple that with rebuilt injectors and a nice clean head ? that thing will run awesome . Yes adding the rings will be sooo much extra work but worth it. Just my two cents though . thanks for the great video.
Matt your content is great,I would say 99% of subscribers enjoy what you do so don’t worry about UTUBE stuff.thanks from Perth Western Australia 🇦🇺👌👌👌👌
I had an Iseki 7000 tractor with a 4BD1 NA motor. i passed it on after 17,000 Hrs with the motor as sweet as ever, only peripheral issues. A great motor.
Matt, Your breadth of knowledge is always impressive. The thoroughness of your inspections leaves little to guessed at. I look forward to your next video every time I finish one. I am in complete agreement with your assessment on your plan.
Matt, I suggest that you make a video about yourself. Let us get to know you a little bit. A tour of your property, general location, meet your family, where do you work and what do you do there, where were you born, how old are you and your YT history. Ithink that would make a long and interesting video. Art from Ohio
The oil pan piece is likely cracking from harmonics/vibration. If it was hit by something you'd have bent pieces instead of everything still being flat. Likely had either a bad spot weld to the pan or a bend that wasn't properly radiused when it was stamped at the factory. Not to mention, if your crank was bent enough to reach and strike it you'd have much larger problems. Poor Charlie in the cone. I chuckled everytime. Hope she gets better.
in spec: run with it. no need to replace what is still serviceable. It would be different if you were selling it and had to warranty it, then it might make sense.
Charlie, poor baby, somehow she knows you love and care for her Matt! I use Sulphur and Vaseline on those hot spots Matt, works great! Praying for your baby girl!🙏🏻
I'm far from an expert on engines, that said, generally in my experience the top half of a bearing shell (piston side of the rod) will generally see the most wear on engines as they take the brunt of the combustion force slamming it against the crank journal. On video, to my eye, those bearings look great. Not a bad looking plant for 9100 hours for sure! Note about blackstone: That's typical. Give it a couple more weeks and you'll find the pdf report in your email inbox. From what I've read they're very busy so it generally takes a little longer than you think it should. Started sending them a urine sample every time I do an oil change on my daily driver diesel for a general checkup. The results they've sent me, doesn't generally sound like favorable conditions for my poor engine, but the thing just keeps asking for more (thankfully!)
I recently tore apart a 4LE1 that had ~50k hours on it with no rebuild. It was running a 25kva generator so putting out maybe 30 horse. The engine was.... immaculate. The bearings were basically reuseable - I was blown away. And this is all with me *trying* to kill it for ~ 2 hours. I drained the oil and ran it at 15kw (that's all it would take with a bad injector) for about an hour. Didn't fail. I then put about 2 cans of ether through the intake hoping to see a rod pop out and say "HI". Still no luck. Literally couldn't kill that engine
I always look forward to you vids Matt. I like the "more action, less jabber" of your content, unlike some other YTs who never stop talking. Keep up the great content and format. Regards from South Africa
i think u are correct for replacing the bearings. cheap Insurances. slide the piston out and replace the rings too. there not very much $. it would have been interesting to see if the valves would hold oil back from leaking through, next time put a couple of 2x4's under the head surface and spray some wd40 in the intake and exhaust ports. if they leak u gota do the valves.
You're video's are great! no need to apologize for what the tube makes you do. there would have to be an imperial ton and then some of adds before your content would be unwatchable. even then i think i would suffer through. As far as im concerned just keep doing what your doing the content is enjoyable to watch. All fingers crossed that Charlies "hot spot?" heals quick and can be back to stooging pears asap. Keep up the great work and thanks for posting!!! P.S. I hope your getting a few bob for the forced adds.
I was glad to hear you say you had ordered the rod and main bearings. You will never get any closer to them than you are. I am not a pro engine builder either. But they are not that much money and you wont be wishing you did it later.
Really enjoy watching your videos. I am amazed by your general knowledge. You know more in general knowledge than a lot of professional techs. I love the look your dog had when you said you were not a expert. Looking out from the cone the look said your are not telling me anything I don't already know. Lol
Being brought up on a farm where money was always tight and time a major consideration i think your right to not go any further with the engine. I would replace the shells but leave the crank, liners and pistons alone. In my fifty plus years of repairs I've found that usually factory fitted original parts are superior to replacement. Better to take a look into the engine and know than not to and to continually wonder....

How would they hone them from the factory?
The fact that thermostat has been removed and rad blocked suggests it was overheated so that makes the rings to lose tension and stick to the groves of the pistons so new rings and deglaze the cylinder bores would be the way to go
Just a reminder change the oil pump
That oil pan baffle was cracked by metal fatigue from vibration. Poor Charlie!
The crack is directly above the heater, so thermal fatigue is more likely.
That’s what I was thinking too, common problem. ..
Engine looks good Matt. Feel for poor Charlie, one of our dogs has two hot spots at the moment, she’s on steroids and an antiseptic wash… I watch your adds, helps you get paid..🇦🇺🍺🍺
Agreed. Weld it up with extra bracing.
I agree.
For a guy who says he doesn't know a lot about engines, I reckon you know a lot more than most of us watching.
I am glad you don't play any stupid music in your videos.
👍👍
Matt, considering you`re no construction plant specialist, you do a pretty good job. Over 40 years doing this has taught me a huge amount in life working all over the UK and overseas, and working with some really good guys. If I could go back, i`d definitely do it all again. Enjoy.

nah that piece that broke off had a bunch of marks on it like it had been kicked around inside the engine
100% 👍
Another great video - Don't sell yourself short - your skill and attention to detail are amazing.
Always a good day when Matt gives us a new video. Thanks Matt.
Matt, it looks like the engine has many hours to go before it goes to the scrapyard. I always like your comments when you work on a project because you know how to analyze a situation. Blessings to you.
Yeah diesel specialists always say unless really down on power don't open a diesel.

Matt, you're doing a great job! Just a hint... get a old plastic milk crate, cut it to sit around the center bottom tube of your engine stand and then you can use a large drain pan sitting on top of it to collect everything when turning the engine over in the future. It makes life simple lol.
hey that's a pretty good trick!
@@elesjuan TH-cam comments are full of great tricks. It's like working for that old man who knows everything
Matt, I had on old time heavy equipment mechanic give me this advice: he said to out a light coat of grease on the fitting before installing radiator hoses. They don't leak and are easy to uninstall and reinstall in the future. I have used this on cars and equipment and never had a problem. Just something to consider.
The Car Wizard does the same.
Thanks for sharing this tip. I'm going to put that to good use.
What kind of grease do you use?
just bearing grease from my grease gun@@579Jacob
I really enjoy this Channel. I've been building and fabricating since 1967. Your approach to this engine is exactly what I would do given its condition and use. Great Job ...
Your calm demeanor and good editing make your videos fun to watch .
I trust your judgement Matt,that engine will go back together and be fine for thousands more hours.

The "wear" on the bearings is just cosmetic. If there's been any metal to metal contact, they get destroyed instantly. Put them back again.

Great engine inspection. It was worth your time to see what condition it is in. It looks like the biggest problem was the missing thermostat and crappy fuel. I do not think that you will be using the machine every day so things are good. I admire your willingness to venture into the unknown and learn as your go. I hope that putting the engine back together goes well. I hope the rest of the machine does not need to much work other than hoses. Love the video and thanks for sharing it. I hope the dog heals fast.
Looks good Matt. If your in there replace the rear main seal as well. Waterpump is toast can hear it from the bearing noise. The craked oil pan is probably vibration from the broken motor mounts.
You and @JustaFewAcresFarm are fast becoming my two favorite TH-cam channels! Full of wisdom, ingenuity, skill and perseverance. Thanks for bringing us along!
😁 WoW .. all you need is new rings bearings and hone the bores .More better than I thought it would be. Great video thanks
Thanks for taking the time and bringing us along, Hope Charlie gets well soon.
Don’t sell yourself short Matt. Your technical abilities would leave me for dead Mate. Your ability to figure things out is incredible. Keep up the work Mate 👍👌
Keep it coming .
I would definitely throw in new bearings at that point , since it is already apart .
Also , new rings as well .
If the pistons are oil cooled be sure to check the check valve springs on the squirters. Sometimes the internal springs fail and allow oil out of the squirters during idle. This can cause you to see low oil pressure. I also reccomend that you check the cam for lift. If the engine ever sat for a long time, it can cause rust on the cam lobes which will cause them to wear out. I would check all of the oil pressure relief valves to be sure they are functioning correctly.
Matt, I headed straight out to my shed and had a look under my bench as I suspect at some stage the original owners of my home had a small bathroom out there, anyway long story short I took the plug cap out of the old faucets and installed new taps and valves and bugger me but it’s still all connected so plumbed my pressure washer and snap, hot water pressure washer, saved myself heaps as had been saving for one, wife very happy = happy wife, happy life. Learn something of everyone of your videos mate….lmao.
also good for giving the dog a bath with warm water
I fully agree on your assessment of the pistons, rods and liners…. But, this far down I would hone the cylinders and throw a set of rings at it. Cheap “what if” insurance. External parts are sometimes a pain, but at least you don’t have to yard the motor again.
When using a telescoping bore gauge, set the gauge a bit bigger than the bore and snug it up, then rock the gauge threw the bore once and measure.
Hi Matt , Good call, As you said the engine is not going to Daytona. Real good shape and this unit will give you years of service around the Farm . thanks. Will be back for more.
Really like your calm demeanor working through these projects and just running the numbers when how to take things apart when you don't have all the data. Also love the 1940s Firestone made by Plomb 1/2 ratchet. A bit of a vintage tool geek/collector so always notice things like that. Anyway keep up the awesome work and content.
I've done a lot of exhaust work being an exhaust business for 30 years your best bet actually is heated red-hot like you did and then shock it hard with cold water!! Spray it down with a spray bottle get it dead cold! And it'll just fly off of there now if it's a brass nut you got to be careful!! They may melt!! You are doing a super great job!!
All the best from Surrey BC Canada
Hello Matt, all seals gaskets bearings you should change, when you have a chance to do that..... All other things are within specifications. or mathing them you can forget them(no need to replace or change them) but seals bearings gaskets you should change. Good luck! see you SOON (as you said) 😏✌
4cyl diesels tend to have bad harmonics and are usually balanced for their high idle speed. Its just a stress fracture in the pan.
Keep up the wonderful work!
Just gotta add my 2cents here-- 10,000 hours?- consider at least some rings and a hone -?? just my opinion I like how well you check things and use your common sense on repairs - keep up the good work(missed the chrome liner info- sorry)
Something to think of. You might want to change the freeze plugs out since you have it torn down this far. It's better to be safe now then later if one fails and have to replace it in the machine.
Never had a freeze plug fail yet seems to be huge issue in the U.S, what's going on with U.S coolant that requires new freeze plugs constantly?
Matt, a rusted bolt you can usually take a air hammer gun with a flat or dull bit and hit the bolts or nuts a little and it shocks them and breaks the rust loose for breaking them loose! Just something I’ve learned throughout the years! Up to you if you want to try it sometime!
Isuzu engineering of these engines is excellent. The Japanese attention to detail make a great product. My 4JB1 is well balanced and smooth running.
You and about 3 other channels are the only reason I still use youtube. Not suprised they are removing those creator options. I will still watch your videos though, top notch content!
Thanks Matt, I appreciate the time you take to examine everything, your explanations as to why or why not do something, your attention to detail is much appreciated, it makes your channel a pleasure to watch. As always stay the course, you will end up with sweet track hoe, looking forward to seeing it in operation.
Enjoy your videos keep it up hope Poor old Charlie gets better soon he looks sorry for himself
*- Matt, your "novice" experience, of getting into and through the tear-down, draws me right onto your stage as someone who has never done such a thing.*
*- Good editing and good copy are to blame for all that...{roaring mirthfully irreverent laughter here}.*
*- It may be slow or tedious for your many viewers who are real mechanics or maintenance experienced machinery owners, but I sure do value the my experience of your "1st time" forensic discovery process at a pace that works well for me.*
Great progress Matt! Tell Charlie that Buddy says get well soon! 👍
Your firewood video was amazing, that’s a lot of wood to handle, split and stack my friend! Good job Matt! I’m praying that this excavator is going to benefit you so much on your property projects my friend! You learn as you go butterflies nobody is perfect and I appreciate your efforts and you sharing everything with us! Using hot water isn’t like using boiling hot water Matt, it’s not going to harm the seals my friend! It’s not hot enough!
Wow it has been a while since the dozer was finished
Love your work hope
Charlie gets better soon, the
Cone is sadly needed to
protect her , until the next
one stay safe 😁
So far every thing i have seen you do is as good as any mechanic i have worked with in my 45 years as a mechanic
I am impressed with your courage and your skills and knowledge even if you are learning from reading just for the project. I have always been the self taught type learning from manuals and such. I would be confident in your work and no sense spending money unnecessarily! 😊
Old school impact, sweet. The vent needs to be run down so it does not let the blow by fill the engine bay. Looks like warm water for cleaning the tank out too.
*- Matt, my vet proscribed antihistamine tablets to stop the hotspot itching issue for my old English Setter. They worked great...check to see if long use of antihistamines is damaging to the kidneys, etc.*
*- Don't take them for yourself in an emergency...you will get dizzy and very loopy.*
*- You might get away with cutting them in half, if you had to use them on yourself.*
Good move on not disassembling the fuel system...I've seen people do that and it's a bear to get it back together...plus yours isn't having any issues.
Poor Charlie...the Cone of Shame! Hope she gets better soon :)
You made me so happy when you said you were just going to replace all those bearings. The way you were talking about them I was worried you were going to leave them. Great video as always Matt!
You sure scored a BUNCH of points with me by tapping the wrench with a hammer. I cringe every time I see someone putting their weight or a cheater pipe on a wrench to loosen a bolt or nut. I recently was called on to help a fellow put bearings in an old rusted 12ft disk harrow. He had a 5 ft cheater pipe and was struggling. I used the appropriate size box end wrench and wacked it a couple of time with a 2lb shop hammer and they came right loose. Too many bolts are broken by not using this method and while it doesn't work every time, it does more times that not. Matter of fact, I have had it loosen fasteners when an impact wrench wouldn't.
I always enjoy your video content. watching you work out problems is informative and makes me realize that I could have done what you do, perhaps better, perhaps worse, but it isn't a mystery. BTW I hope Charly's hot spot get better. She is a great looking dog.
Thanks for the hard work in producing and editing these videos, Matt, which are unspoiled by histrionic voices and wordy gush. I also appreciate your "If it ain't broke don't fix it" approach. Poor ole Puppers wearing, much to the loss of her personal dignity, an Elizabeth collar!
I have the same excavator. I had to get the fuel pump rebuilt, that was expensive. I would like to see you setup the engine speed sensor when you get there... I am getting a warning on it.
Be very careful of your fuel tank... take it off and clean it super well! That has bit me bad. I saw on my other favorite channel, farmcraft, he had a ton of issues with that too on his new to him dozer.
Engine looks good inside. I think you did well with this purchase.
Poor Charlie ! Such a good dog.
Another great video, Matt! I hope Charlie gets better, as she didn't look too happy with the Cone of Shame.
The first hillbilly thing I saw Matt do:
Put liquid that evaporates at temperature X on parts with temperature > X. Like when I tried to rust proof an exhaust with petroleum jelly.
Good video as usual I'm and happy to see there was no hidden carnage lurking inside the engine.
even if not an expert, you are good at camerawork and talking to the camera usefully. The term 'dilettante' has some negative connotations, but it's not necessarily a bad thing to dabble in a lot of skillsets without committing to becoming an expert: it makes you versatile. and you seem to have worked around enough engines to know what you're looking at WRT wear and engine high operating hours. (it's impressive that this engine is still this fresh with 9000 hours on the ticker)
I am an engine builder . Race cars mostly. you do the new bearings like your saying with new rings and that motor with decent care will outlive you. Couple that with rebuilt injectors and a nice clean head ? that thing will run awesome . Yes adding the rings will be sooo much extra work but worth it. Just my two cents though . thanks for the great video.
Matt your content is great,I would say 99% of subscribers enjoy what you do so don’t worry about UTUBE stuff.thanks from Perth Western Australia 🇦🇺👌👌👌👌
Great work Matt , there's a bunch of us over here in the UK who wait with baited breath for your video's keep up the great work 👍
I had an Iseki 7000 tractor with a 4BD1 NA motor. i passed it on after 17,000 Hrs with the motor as sweet as ever, only peripheral issues. A great motor.
Matt, Your breadth of knowledge is always impressive. The thoroughness of your inspections leaves little to guessed at.
I look forward to your next video every time I finish one.
I am in complete agreement with your assessment on your plan.
Nice to see you again. Thanks. Gentle ear chuckles and head pats to Charlie!
Matt, I suggest that you make a video about yourself. Let us get to know you a little bit. A tour of your property, general location, meet your family, where do you work and what do you do there, where were you born, how old are you and your YT history.
Ithink that would make a long and interesting video.

These series are worth the wait.
The oil pan piece is likely cracking from harmonics/vibration. If it was hit by something you'd have bent pieces instead of everything still being flat. Likely had either a bad spot weld to the pan or a bend that wasn't properly radiused when it was stamped at the factory. Not to mention, if your crank was bent enough to reach and strike it you'd have much larger problems.
Poor Charlie in the cone. I chuckled everytime. Hope she gets better.
Thank you for the cost analysis. That's really helpful to see.
in spec: run with it. no need to replace what is still serviceable. It would be different if you were selling it and had to warranty it, then it might make sense.
Charlie, poor baby, somehow she knows you love and care for her Matt! I use Sulphur and Vaseline on those hot spots Matt, works great! Praying for your baby girl!🙏🏻
That's one tough pressure washer pump. The supply water is what should keep it from overheating.
I'm far from an expert on engines, that said, generally in my experience the top half of a bearing shell (piston side of the rod) will generally see the most wear on engines as they take the brunt of the combustion force slamming it against the crank journal. On video, to my eye, those bearings look great. Not a bad looking plant for 9100 hours for sure!
Note about blackstone: That's typical. Give it a couple more weeks and you'll find the pdf report in your email inbox. From what I've read they're very busy so it generally takes a little longer than you think it should. Started sending them a urine sample every time I do an oil change on my daily driver diesel for a general checkup. The results they've sent me, doesn't generally sound like favorable conditions for my poor engine, but the thing just keeps asking for more (thankfully!)
Good call on the bearings and rings. Easy to change out now and with oem parts is also a plus. No worry about the ads here.
I recently tore apart a 4LE1 that had ~50k hours on it with no rebuild. It was running a 25kva generator so putting out maybe 30 horse. The engine was.... immaculate. The bearings were basically reuseable - I was blown away. And this is all with me *trying* to kill it for ~ 2 hours. I drained the oil and ran it at 15kw (that's all it would take with a bad injector) for about an hour. Didn't fail. I then put about 2 cans of ether through the intake hoping to see a rod pop out and say "HI". Still no luck. Literally couldn't kill that engine
I always look forward to you vids Matt. I like the "more action, less jabber" of your content, unlike some other YTs who never stop talking. Keep up the great content and format.
Regards from South Africa
Push the rings into the bore and measure the gap with feeler gauges. There are specs for tolerance.
i think u are correct for replacing the bearings. cheap Insurances. slide the piston out and replace the rings too. there not very much $.
it would have been interesting to see if the valves would hold oil back from leaking through, next time put a couple of 2x4's under the head surface and spray some wd40 in the intake and exhaust ports. if they leak u gota do the valves.
We have yard spotter trucks that have over 40,000 hours on them before they're put out to pasture. Cummins 6.7L
Thanks. Very surprised that the rear main had a full groove unlike the others!! Also that it seemed to be the sane size!
might CLR the water passages 20 bucks to clean them might be a thought, great tear down and inspection
You're video's are great! no need to apologize for what the tube makes you do. there would have to be an imperial ton and then some of adds before your content would be unwatchable. even then i think i would suffer through. As far as im concerned just keep doing what your doing the content is enjoyable to watch. All fingers crossed that Charlies "hot spot?" heals quick and can be back to stooging pears asap. Keep up the great work and thanks for posting!!! P.S. I hope your getting a few bob for the forced adds.
I was glad to hear you say you had ordered the rod and main bearings. You will never get any closer to them than you are. I am not a pro engine builder either. But they are not that much money and you wont be wishing you did it later.
Really enjoy watching your videos. I am amazed by your general knowledge. You know more in general knowledge than a lot of professional techs. I love the look your dog had when you said you were not a expert. Looking out from the cone the look said your are not telling me anything I don't already know. Lol
Being brought up on a farm where money was always tight and time a major consideration i think your right to not go any further with the engine. I would replace the shells but leave the crank, liners and pistons alone.
In my fifty plus years of repairs I've found that usually factory fitted original parts are superior to replacement.
Better to take a look into the engine and know than not to and to continually wonder....
