- More investigation into the cause of the overheating and damages to the engine. Worst radiator I’ve ever seen, water getting into a cylinder and into the oil pan.
Informative, entertaining, and just fun to watch. Should be a reality TV show. Thanks for sharing.
Why does vacuuming an old bus engine seem so satisfying? Thank you for another great video.
Hey!! That's my wrench. Lost that years ago..... wondered what happened to it.
LOL !!!
Hi There
I am in the UK with 2 8V-923TA engines in my boat, with 1 that had water in the oil, so within a few days, I'll be at your stage; your information is precious to me; Thank you ever so much; shame you are not here in the UK, or maybe I could get you to fix my engine also haha
That radiator as a whole is a done deal.
Yeah, even if they get the passages open the surface rust on the outside is awful! Seems like fitting an aluminum unit, if a suitable one could be found, would be smart. What a disaster :(
@@BLKMGK4 just needs to be recored
Lots of solder blume, but those usually clean fine, as a mechanic who owned a radiator shop, I would take a brass and steel core over aluminum any day.
Scott I've used Gilley's lye from the Laundry section of grocery store, An old transport mechanic showed me once using it With hot water he spilt some on the bumper it stained the chrome but completely opened the rad up ,But it was still together ran it with engine running, Won't believe what came out nasty ,Same as rad shop 😮.
Great work Scott I enjoy your videos,and I can’t be easy,fixing years of neglect
All the best to you all for 2024
Cheers

I've added $10k with every episode on this Wanderlodge after staring at $5k when it was unloaded. We're close to $30k now. If the owner gets out for under $40k, it will be a surprise to me. Scott hasn't gotten to the air/suspension/brakes issues.
That is a badly maintained engine once upon a time...definitely has had a hard life. Given so many fins are gone on the engine side will the core be salvageable assuming it rods out okay?? This video is a PERFECT example of why not to run straight water in anything you care about surviving. That bottom tank looks nasty...hopefully all of the black seen when you scraped in it a bit isn't rust that's eaten away at the tank.
The owner will have a lot of money in this repair but that puppy's gonna run and perform like it looks...beautiful. A long job but i just hope as long as that's leaked water internally that the bearings aren't wiped out.
A great video as always Scott🙂
That bus and me have a lot in common, years and years of great service, and a whole lot of abuse. I wonder if my ex ever owned it?
You and me both. 😅
The difference is that the bus didn't have a choice 😉
Excuses.
@@gregculverwell It's not easy when kids are involved.
Lol
Mosquito fogger right there! Nice work, bro!💪👊
"well there's yer problem.....and that......and that......oh and that too"
When seperating the radiator, consider keeping the chisel perpendicular to avoid flange damage. Resist the urge to flex it up and down. Also, popsicle sticks as place holders when the gap opens enough. Armchair mechanic here.
I am an old master mechanic, diesel and car and I just learned something about my Jeep. The Pentastar engine grenaded once for the valve train and other components and when it was delivered to me the same thing happened and the head had to be replaced. I was suspicious and took a oil sample and when it came back it showed coolant in the oil. When I met with the service manager he told me that the Pentastar engines were having problems with coolant seeping through the cylinder walls when shut off. They are going to put a bore-scope in overnight so they can get photos for the warranty to replace the engine. He said they have replaced a number of the engines for this problem. There are no cracks just pinholes in the cylinder walls. The only other block I remember doing this is the Ford 7.3 if the additive wasn't put in the coolant. I wish gas engined were made with sleeves but I guess it would cost too much.
Many gas engines are made with sleeves but pulling and refitting them is a whole different ballgame than on one of these beasts :(
Another great video Scott,always a pleasure and so informative.
I invest in 1/8" and 3/16" solid carbide drill bits when working on stuff like that. They drill thru anything like butter. Just had to drill thru a broken hardened easy-out stuck in a cummins 8.3 exhaust block port... No other drill but could do it and welding a nut wouldn't work after repeated tries because the weld keep pulling in the harden steel and was just to brittle to hold torque. Saved me from pulling the engine block. Got the easy-out completely out and saved the block threads... Spendy and easy to break but in a pinch they come in pretty handy at times.
I’ve heard that a flush with CLR will clear a lot of the crap out of heater cores and radiators, you set up a flush with a recirculating pump. Don’t let it run too long, though.
Believe it or not...2oz of MotorKote in the radiator...it will coat the inside of the metal and help prevent rust and corrosion...only problem is...all the rusty crap in the engine block will end up breaking free and settling in the radiator...so a flush after treatment is a pretty good idea!
Keep em coming!!!!
The lesson here in living, yucky color? Don't use the garden hose to fill the radiator! Not unless it's a last resort kind of thing to be made right first chance you get. Another good one. Cheers! 👍
Water as coolant will work in a pinch for an emergency, but not for long time use. A friend of mine found that out the hard way. Fortunately his problems were relatively easy to solve but it cost him more than a can of proper coolant would have 😅
SCA's, Selective Coolant Additives. Very important. Cavitation/ corrosion/ electrolysis is no joke folks. Grab an OTC 6043, great flushing tool. Good use to flush coolant lines, cooling jackets, rads and heater cores.
SUPPLEMENTAL Coolant Additive.
If there was ever an advertisement for regular coolant changes this is it.
I have some large john deere diesel cylinders that actually got pin holes in them because of not using coolant!! Under pressure test, small amounts of water was dripping off the crank.
It's cool to see y'all wrenchin again, how's Lenny coming along?
Or finding wrenches. 😂
I think that radiator needs to go into the scrap pile , or head to radiator shop … it’s pretty toast. ( I’m still watching)
Proves that Straight Water isn’t the best answer to the needs and the missing additives that the coolant provides for the engine works in many ways like the electrolytes that plain water is missing for our bodies. When the miles start adding up the areas of neglect compile and there isn’t always a replacement or fix!
Take care of things!
A mini sledge (in the 3-4-5 pound range) should be in every mechanics and/or handy man's too box. So useful in so many ways.👍
Yes it is!😉
A various assortment of hammers. No wrenches I knew a guy who used that system . Borrowed wrenches from everyone .
Looking at the air filter it looks like that engine could have injected a bunch of dirt through the turbo. I think they call that “dusted” and do you ever find cracks between the coolant holes in the block?
It might be worth considering. If the radiator core is that bad...the engine water ways are going to have similar buildup. Would you run a coolant flush through the system first. Before draining and filling with proper coolant. As all it would need is for some of the silt to dislodge out of the engine to work its way back to the radiator and create blockages again.
It’s not his first day. I think he’s got a handle on it.
I can say from experience that water in the oil will wear away babbitt bearings very quickly. That includes connecting rods and wrist pins, not just the mains.
I'd go over the radiator with the high pressure sprayer first then rod out the tubes. Finally i'd soak it overnight in Evaporust then rinse it out. In fact an overnight soak of Evaporust soak in the whole block might be a good idea.
Scott,
Wouldn't liner height have something to do with that one cylinder ending up like that. Meaning that if that particular liner was set say a few thousands lower, cause it to start leaking?
😮 In my opinion, as bad as the radiator is, the cooling jacket in the block is likely full of the same junk. (Gotta love stop leak) I'd send the block & heads to the machine shop.
I see a trip to Nashville for the radiator. What a mess. Was the deck straight?
There's a good radiator shop in Denver, NC that can recore that radiator.
There used to be radiator repair shops that could sort things like that out pretty well. Do they still exist or is everything just throw away and replace these days?
Radiator shops are still out there. Had the OE radiator in my 32 year old Dodge recored last year.
Hard to find a shop in my area.
Seems like good radiator shops are a dying trade. You may still find shops to do truck and bus radiators, but metal small vehicle radiators have almost gone to plastic top and bottom tanks (non repairable).
My local shut down a while ago. You could show up, turn in the radiator and they'd hand you a ticket for receipt. "come back in a couple days" 😢
They exist but not many around. Lucky for me, there is one near me in Northern Virginia. Very handy. They also do starters, alternators generators (if you have older car). Been there over 75 years. Used them a couple times for both radiator work and generator rebuild.
Hope this guy has some deep pockets. I'm sure there are more surprises to come.
Great video. How do you check the block for flatness when doing.an inframe?
Could the liner o-rings also be leaking. That looked like and awful lot of water running into the sump!
I wondered the same thing myself, especially with the amount of corrosion on the head to block o-rings pretty much every cooling system seal will likely have the same problem.
We used Nalcool 2000 by the drums, Correct me if I'm wrong, but don't you have to replace the liner seals in the 92 series once it has been over heated?
Scott are those radiators so expensive that you can save money by doing all that labor? That thing looks pretty bad to me!
Is it really worth fixing that radiator with all those issues? Seems like after all the labor to fix it you have a ticking bomb for leaks!
My thoughts exactly, why bother fixing it? It's junk.
On something like this, would it be worthwhile to pop all the liners out and at least put new orings on?
I don’t understand why people don’t put the proper coolant for the vehicle in radiators, the cost is insignificant by comparison to the long term damage!
These are very expensive vehicles too. Only southerners do this long term ;) i know some northerners that have tried it though
People use water when there’s a leak in the system - in that situation water is a lot cheaper than coolant. And it’s not a good deal to be leaving antifreeze on the ground wherever you go..
I'm only eight minutes into the video. This looks like a complete in-frame rebuild to me since you have it torn apart so much. That is going to cost a pretty penny! In for a penny, in for a pound.
Nice protective layer applied on the radiator. 😉
If you "Cook" a Detroit youv'e got trouble all the way down,there are no short cuts .
You going to check the camshaft?
How is the new conex cover holding up with all the wind we are having in Middle Tennessee?
Hey Scott as I watch this there were 6,045 views, and at this point in the video which is about halfway through all of a sudden it's 6,075
What is the procedure for sealing all the new o-rings into a somewhat pitted seats instead of a nicely machined seats?
I’ve never seen nicely machined ones. ;) They are usually a bit crispy on this old stuff
@@BusGreaseMonkey OK so the o-rings will just drop in to a fairly rough surface and seal,, well that's good !!
Would an oscillating multi tool make short work of separating those pieces? Assuming you can keep it under control.
Hey it looks like he also have your own coral reef in the bottom of the radiator
Are you going to replace the radiator?
...it has to be a hard decision ...but when do you reach the point where NEW is actually better/cheaper than rebuilding existing?
It will be interesting to see what comes out with the liners. With all that crap, I bet they will be hard to pull>>lots or corrosion and gunk on the o-rings. If the inside of the block looks like the inside of the radiator, I think I'd pull the whole engine and have it tanked and checked for cracks. probably cheaper to find another engine. Some clueless people just should own cars, trucks, motor homes, houses, ANYTHING! Feel bad for the poor person that buys these disasters after the previous owner mucks it all up.
Have you thought about getting a laser cleaning machine? Removes rust, paint, oil, grease.
They are nice, just horribly expensive. So far.
And I do mean HORRIBLY expensive, for a good one. Cheap one start around $5,300.00 USD, better ones, $12,000.00 and up.
I need to raise my prices by about $250 per hour just to be able to afford to buy a fraction of the stuff people on the internet say i need…
@@BusGreaseMonkey Then it arrives and you use it once and it sits on a shelf for decades waiting for the next customer with a forty-year-old radiator that needs to be repaired!
@@BusGreaseMonkey I agree, I can't justify half of the fancy equipment.
Best wishes, hope the worst of this storm, is no where near you.
How many hours can you put into refurbishing that rad before replacing it is more economical?
Well, for the answer, you'd need to know the price of a replacement. Go out and try to find one. Doubt you'll find any sitting around on a shelf, so you'll have to have one made to spec. In addition to the price, how long can the project wait for a proper replacement to be found or made? This one is still serviceable, after 8 hours of labor. Ready to go back into service, and as Scott figured, good for probably another ten years, maybe more if it got painted and protected.
Please mention sometime if a new radiator can even be sourced and how much? My guess is it could be as high as 4-5k new?
$10k
With the heads and pan off are you not going to replace the liner o rings ?
Of course we are but we are making sure the block is good before we start rebuilding it.
The inside of the radiator looks like there are barnacles living inside it. Probably also wise to wash out the block cause there might be nasty things inside it as well. Thermostats should be replaced also at this point.
Are ya gonna pull liners? As bad as the cooling system is, I’d be worried about cavitation…
Of course we are
@@BusGreaseMonkey Silly question! In for a penny, in for a pound…
do you have to sent your heads out of town or is there a local shop
Holy s! Is that radiator even repairable?
Scott is it the worst shape of a cooling system or you have seen worst in the past ?
Unfortunately no

@@BusGreaseMonkey this is a nasty mess but it's not the worst cooling system i ever saw either ,,worst radiator i ever worked on was the radiator in my peterbilt 359 ,,it was so corroded and filthy it looked like it had salt water in it for coolant ,,it took a full removal of the engine and sending it to a machine shop for a boil out to get the rust out of the block
The Turbo compressor wheel blades look bend at the beginning of the video.
Looks like fun.
I’d put a new rad in it. I’m sure they are expensive but that one is going to be nothing but trouble.
Looks like it’s time for a NEW radiator and a rebuilt engine and she’ll be back on the road soon.
It's amazing people dont check their cooling systems more.
Pretty obvious if you look at the rad fins lol.
It's hard to miss.
I missed the intro - am I to assume that the current owner bought this coach in this condition??
keep the clips coming
Inside that radiator looks like Moab after a rain storm.
Hey Scott I think somebody got in bind and put creek water in the bus
It has been going on for a loooonnngg time that didnt happen over night , probaly over 5 years & or very bad bad water. Was in Battle mtn Nevada & cummins with bad counter bores put town tap water at service station, drove 70 miles i thought i put barn red paint in engine!! ( bad water)
Kroil for the win. Best stuff made.
Looks like that water came out of the creek.
OMG you found the monkey wrench!! 😮 The curse is lifted and the bus just got a new lease on life, in more ways than one. 😊
See how this failed - I would think rust jacking action against the head and block basically caused the boring failure which eventually jacked everything up to allow it into the pistons. I wonder which actually caused the failure - the o ring itself or the rust. Ultimately it comes down to use the proper coolant!
This was supposed to say “interesting to see how this failed”
Those radiator shots remind me of video from the Titanic on the bottom of the ocean....yikes!
I don't envy you and the that radiator one bit
You found someone’s missing 10 mm Scott 😂😂😂😂
What about the o-rings on the cylinder sleeves. Aren’t the 92’s wet sleeve engines?
that rad is dun
boy, that is a whole job in itself just dealing with that radiator getting it apart. let alone trying to clean it all out. water is cheap,,,,,,but not for long!,,,,,,,,,,,,,,,coolant could have saved thousands in the long run.
so much neglect..........and people wonder why break downs happen.
that radiator looks like it could do with a dip in a hot caustic tank
Looks like dex cool resido
That ting looks like you should fill it with evaporust once you've rebuilt it....... OMG that thing is allmost gone....
It doesn't look like someone took very good care of the engine area.
Yikes, that's what I call job security
Yellowstone mud pots in the radiator !
That core is JUNK
Looks like it had a great mud bath
U got this
That radiator is junk. The copper fins are falling apart. Needs to be recored or new replacement. I've recore hundreds of radiators.
I think Scott knows it's junk. He let the owner take it apart to show him what mistreating an engine will do to your wallet.
EWEEHHHH😬 the BA-CHA-CHING radiator 😅
Over heating strikes again like the grim reaper . Causing mass destruction .
Owners not doing enough maintenance ,,simple as pressurising cooling system every service ie 6--12 mths . Could be simply avoided .
Some owners donot no what mechanical sympathy is ...............
A 8 v 92 turboed and after cooled lots of power!!! Be a hot rod when you are done.
even the radiator end tanks might be rust pitted bad.
Detroit's would crack a cylinder head if you over heated them.
Someone went on a fishing trip and parked that bus at a campsite near the river, the river water must have been used to fill the radiator.............bring a new radiator..........!
I doubt that radiator will withstand a cleaning
My thoughts too, just replace it.
@itjustlookslikethis The core is rotted Away. Lots of fins are gone
