9100 hours on this excavator engine...how worn out is it? Isuzu 4BD1T

[@PacificNorthwestHillbilly]

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!

[@petesmith8000]

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.

[@woodhonky3890]

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!

[@Elyjah1]

How would they hone them from the factory?

[@yodadg7]

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

[@matthewclarke7993]

Just a reminder change the oil pump

[@cooldog60]

I am glad you don't play any stupid music in your videos.

[@Watchyn_Yarwood]

👍👍

[@woodhonky3890]

That oil pan baffle was cracked by metal fatigue from vibration. Poor Charlie!

[@robertgarrett5009]

The crack is directly above the heater, so thermal fatigue is more likely.

[@phillipdean9879]

That’s what I was thinking too, common problem. ..

[@phillipdean9879]

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..🇦🇺🍺🍺

[@jonathanfenne4948]

Agreed. Weld it up with extra bracing.

[@silasmarner7586]

I agree.

[@45sunnybank48]

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.

[@lifeafterourloss]

Great progress Matt! Tell Charlie that Buddy says get well soon! 👍

[@davidlatham9675]

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

[@jb_makesgames2264]

Another great video - Don't sell yourself short - your skill and attention to detail are amazing.

[@qlimaxbass5022]

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) 😏✌

[@rr3102]

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!

[@danielbuxton2656]

Your calm demeanor and good editing make your videos fun to watch .

[@jeffh5664]

Always a good day when Matt gives us a new video. Thanks Matt.

[@flowerstone]

Cleaning up takes the stress off and makes a person motivated to start the next project. 😊

[@paulblankinship9964]

Your KZbin 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.

[@mikeb1]

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.

[@brianelliot2719]

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! 😊

[@RockhopperPE]

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

[@PacificNorthwestHillbilly]

nah that piece that broke off had a bunch of marks on it like it had been kicked around inside the engine

[@Watchyn_Yarwood]

100% 👍

[@stevecorey3399]

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.

[@dustcommander100]

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!

[@francisbarbeau1862]

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.

Yeah cleaning out the fuel tank is definitely on the list

[@richardgreen7811]

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 ...

[@robertsettle4727]

Isuzu engineering of these engines is excellent. The Japanese attention to detail make a great product. My 4JB1 is well balanced and smooth running.

[@lastguy8613]

Dont be so bashfull about youtube ads, I want to see you get paid for your work and the extra time it takes to film all this and am quite happy to watch a few ads over 40 mins. People who whine about them need to remember the saying that if you dont pay for the product you are the product lol. Keep on wrenching!!

[@bobferranti5222]

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.

[@elesjuan]

hey that's a pretty good trick!

[@chechnya]

​@@elesjuan KZbin comments are full of great tricks. It's like working for that old man who knows everything

[@williamwallace7299]

Was glad to hear you’re replacing the bearings.

[@RobertFay]

*- 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.*

[@dennisbailey4296]

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

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

[@utubota5522]

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.

[@CajunGreenMan]

The Car Wizard does the same.

[@tellyfaulkner3466]

*- 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.*

[@billroberts3864]

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.

[@georgevindo]

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.

[@einfelder8262]

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.

[@benruether8294]

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

[@zippo1009]

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 KZbin!

[@929cbr_rr]

Engine looks good inside. I think you did well with this purchase. Poor Charlie ! Such a good dog.

[@Watchyn_Yarwood]

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.

[@aladarmezga4942]

Yours is one of my favourite channels honestly! Thank you for your work!

[@bigblocklawyer]

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.

[@thomasr.miller5553]

😁 WoW .. all you need is new rings bearings and hone the bores .More better than I thought it would be. Great video thanks

[@kaboom4679]

Keep it coming . I would definitely throw in new bearings at that point , since it is already apart . Also , new rings as well .

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.

[@joelsokoloff1980]

Thank you for the cost analysis. That's really helpful to see.

[@Hyratel]

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)

[@RobTuck1475]

[@davepflum7712]

Clamp down your liners, especially if you Re-ring it. The tension of new rings could pop the liners looseand result in more tear down.

[@stephensklein6952]

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 :).

[@peteacher52]

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!

[@markr478]

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)

[@terryrogers1025]

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, 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.

[@PacificNorthwestHillbilly]

also good for giving the dog a bath with warm water

[@one4stevo]

Great video. hope Charlie recovers soon. Beautiful Dog he is

[@SuperMAZ007]

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.

[@carl4323]

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.

[@captnsquid8151]

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.

[@joelx77]

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.

[@buttonmonkey6845]

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 😀👋🇬🇧

[@jaycroyle8761]

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.

[@erik_dk842]

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.

[@mujgy]

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!

Good video as usual I'm and happy to see there was no hidden carnage lurking inside the engine.

[@alanm3438]

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.

[@josephgriffiths7656]

The oil pan, I'd say it's just thin sheet steel that has fatigued and broken overtime , I'd not worry about it (does need to be fixed however). The bearings are nearing the end of life, they've worn through the main layer by the looks of it and if kept would cause actual damage over time but replacing them now (as you are) is the proper thing to do and will massively extend the engines life. I'd leave the pistons, liners and rings you'll gain nothing there. I'd expect at least another 3,000-5,000 hours out of that engine on those piston and liners as they are before it needs real attention there imo. Check the oil pump clearances and tolerances however. Another quality video again. Poor doggie tho 😂

[@booterone1]

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.

When doing this kind of work, it is mandatory to change the rings on the pistons, then the crankshaft bearings (at least connecting road bearings), and completely arrange the engine head-valves and valve seats , checl valve guides tolerance.
