Boring video today... sorry it’s not exciting stuff. That will come tomorrow. Setting up the heads of this 8v92TA detroit diesel Wanderlodge bus rebuild
Hi Nice job on the injector tubes, super that you got the tools to do them right, shops are obviously not up to the job, Lenny ran so much smoother after Joe set them right, and now you can do the same, a good old handmade thumbs up.
I scrolled through the comments before I opted to add my own..& this is it: With my cars, if I didn't do the work on them myself, I was very, let's say, exacting on who laid hands on them. And even with that, there were times when my cars came back different(and not in a good way) from when I dropped them off. This from supposedly "trained technicians". If this is my bus, my $1500, that machine shop had better be top notch - because the technicians that are coming cross-country to service my bus don't have a moment to waste. Every moment spent having to redo something is a moment stolen from the final assembly & testing, & you can bet I'd "put you on blast" if my parts come back worse off than when they left. Time to name names - you've got 70K+ subscribers behind you... we may not all own buses/coaches, but none of us would appreciate paying for sloppy workmanship.
Back in the last century I had a valve job done on a slant six and after the machining they put it in the hot tank. There was so much sludge in the ports I had to disassemble everything! Crap work has always been around.
They probably oiled the heads to prevent rust and the shop had some grinding or polishing dust floating around, and attached to the wet surface. Good job! 👍👍👍👍👍👍
Scott: another vote for cheap MDX plywood. Trust me, I used t live down there in tomball Tx. The dirt is too soft especially when wet! It will be the best $20 bucks the owner can spend!!!!! BUY 3/4” PLYWOOD THAT SHIT LOOKS HEAVY!!! Just imagine the extra labor hours lost fighting the soft dirt with lifting heads it’s a no brainer for me! I love the channel. You are living my dream (not my wife’s dream - like TH modern junk) but I almost talked her into a 80’s Wanderlodge, the cat 3208 kinda scared me off. But you have instilled faith in the Detroits) I love vintage busses.
I ALWAYS DO MY OWN HEAD WORK! I have a 3ANGLE VALVE GRINDER & I CAN CUT THE VALVE GUIDES OUT & DRIVE NEW ONES BACK IN! If need be I can remove & replace the valve seats! Also can Deck the Head! I invested in the machines around 35yrs ago & have updated to newer ones as time has went on! If u are ever near Wv & need it done I can do it & it will be done rite! I have a place in Midland Nc that I go to get away from time to time! Which is just a rocks throw from Albermarel Nc!
After all the “work” was done to those heads, they should have been hot tanked one last time to get the grinding grit out of them, then masked off and painted before final assembly. You will now have grinding grit distributed throughout your engine courtesy of the valve job.
If It were my cylinder heads I would removing a valve or four and inspecting the valves to make sure they were properly machined, giving the valves the wiggle test in the guides, looking rather closely at the valve seats etc. I can accept the heads being painted the wrong color but a head that is dirty sets alarms off in my book. It would stink to put the heads together and then have problems and be tearing them back off again. Perhaps it time to find a semi retired Detroit Diesel guild machinist that is still taking in work. O well just a thought. Keeping my toes crossed for you all that everything goes as planned.
That head doesn't just have 'dirt' on it, it's more residual machining grinding / polishing compound, right? Wouldn't that be a huge bearing wear issue once it gets into the oil??
Dell Anderson yes it would but Scott will clean them with brake clean or something I’m sure before he installs them to make sure that doesn’t happen. We all know to well by now that Scott would not install an inferior part until and will do whatever he needs to do to make it perfect before the install. He is one of the few mechanics left that has pride of his work left and is not gonna take shortcuts. That’s why there is 70,000+ of us here now everyday.
The real problem is in assuming that a specific machine shop knows what needs to be done. There once was a time, when there was enough of that type of work that as people advanced in the career as a machinist they learned from older more experienced guys. No more. Today, the people doing the Work know just enough to turn out product that looks right. They don’t actually know what to do, and unless the customer can be very specific in his requirements and is willing to verify that the work was done correctly, you get what you get. The take away is, never assume the person working for you knows his job.
Love the videos! Keep up the great work, you’re very thorough and that’s something that is lists with a lot of today’s techs.. also I saw my first silverside in person today and it’s was freaking beautiful!
Once got a head from a shop, all the bolt holes were full of grit. Like the solvent bath solvent must have been full of garbage. Had to thread chase all of them. But only the bolt holes, everything else was spotless.
I agree with the other comments. Scott when you run into lousy machine work, which I have seen disturbingly often in your videos, it is definitely time to start naming names, so others aren't victimized by the same lousy work.
I hoped the weather would have been better for ya'll today. Most machine shops are getting shoddy in their work. Per the customer's request at the time. The one in our town sent me a set of Ford 6.0L heads that were as dirty as they were when they came off the truck. Very disappointing in their workmanship. I send everything to Dover Cylinder Head. I have never had any issues with Dover. They are a little more expensive but it's worth it. Sorry for the rant.
Never assume anything that comes back from the machine shop is clean. If you get assembled stuff, take it apart and measure everything and clean it. Same goes for "factory".
I'd be pulling some valves to make sure they are done right. What a halfass job. This is the same luck I have with custom work. Pretty basic stuff. NAME NAMES so we don't use them!
AGREED!! Scott, its time to start naming some names when it comes to machine shops that do shoddy work like this so said shops start learning DAMN QUICK they BETTER start taking their quality of work SERIOUSLY, or they lose all their business and suddenly declaring bankruptcy!
porkbuttrocks and there are a lot of us from this local area of NC watching so we do really need to know who can be trusted and who can’t be. I’m gonna be doing the same work probly in the next year or so and I don’t want to give someone $1,500-$2,000 to do a half ass job!! That price demands that job be absolutely perfect and the right COLOR!!!!! Thank you Scott for all you do for all of us!
Oh man please video valve and rack adjustment as well as injector install. Hardly any info on 8v92 build on the tube. I really appreciate your videos, thank you.👍
BGM. Maybe whomp up a check list of what you will be looking for after a head rebuild . Make it part of the deal with the shop . I do wood machining and I the same thing to keep things simple .
They painted those heads as a tribute to the Mint Green '63 Pontiac Tempest that robbed the 'Sack O Suds' in 'My Cousin Vinny.' (Corvair also had independant rear suspension in addition to the Corvette.)
I would be wondering just how clean the tubs were when they preset them in? is there small dirt under that will be a major problem latter was the valve guides replaced or just cleaned up to look pretty???
I think its time Scott started naming some names when it comes to this sort of stuff so the shops that don't have any concern for quality of their work and pride in it start legitmately losing some business and feeling some real financial pain for their half-finished work.
@@MrShobar Rats. Well I think we got our reason why these machine shops continue to remain nameless. Still doesn't seem right at all, that said shops can then seemingly get away with doing only half-finished work like this.
BusGreaseMonkey needs a www.summitracing.com/parts/pow-pow101310/overview/ to go with his dial indicator to make his life so much easier checking injector protrusion and liner height.. its not something that could not be cobbled up on a drill press in 30 minutes.. i have seen them made out of connecting rod caps.. but extensions may be needed.. magnetic dial indicator bridges are also available..
I'm with the other guys, pull some valves and check the surfaces, plus I would be spraying carb cleaner everywhere because that dirt could be from the surface grinding.....🤨 It's called "covering your ass".
Looks like there are a series of square drive plugs along the fuel passageway? Can anyone tell me why those are there and if you have to 'set' them in any way? Thank you!!
@@BusGreaseMonkey It’s an honor sir and thanks so much for your reply!! Really enjoy the channel as I have a Hatteras boat that has twin 8v92 TAs and we are fellow Tennesseeans!
Mr. Bus Grease Monkey, off subject, but are you aware of anyone who's successfully towed a trailer with these buses? Something in the 8-10K lb range without buckling the chassis? Thanks.
Having noted the errors made by the machine shop, particularly in respect to the dirt you saw on the head, Why did you continue with the heads assembly with the dirt still evident?
Because it was raining outside and i couldn’t clean them in the trailer or I’d have fumed myself out. Tomorrow they’ll get a brake clean bath and be clean
How does a machine shop not know the color of GM Diesel Green?! Buick used basically the same color on all their early nailhead V8 engines, from 1953 through at least 1959 and maybe later.
Used to work on diesel engines machine shop repair facility. First I saw was Cummins doing recon program turn your cylinder heads in they give you three that been manufactured in Mexico. Same with all the manufacturers machine shops couldn't stay in business started taking a big hit. We used to build engine that was in your truck now you just trade it out. I seen this Recon crap I'll still rebuild my own just too old to do it. Be sure to check where the ejector seats notice you were cutting them very very very easy to cut them too thin and they'll crack dumpwater I'm telling you that engine is a piece of crap. But good luck.
Those copper injector cups hold the injector into the head, and coolant runs around them to keep them cool. If the cup is not pressed in right, or the thickness of the cup is off from the others, the injector tip will either stick out too far or not enough. And since the injection event is also the combustion event, it can mess up the timing of that cylinder. As Scott was showing, they are within limits, but making them all the same gives the best performance, and is also perfectionist work! The speed drill he was turning was shaving off some of the metal inside the injector cup so when the injector is put in place, the tip extends to where it should within the cylinder. To the naked eye, you would not notice the variance. However when driving, you could. Just some fun things with Diesel engines!
Very tedious work building a diesel properly. I know you know Stu from Dangar Marine. He had a friend of his rebuild his blower and fuel pump, and Regulator. He seems to really know what he is doing. You may want to have a look at the video rebuild of it. th-cam.com/video/6_KKNooC8nM/w-d-xo.html Really look like he had his act together. You might be able to get some tips if you get stuck at some point in the future. I know as a Automotive Mechanic myself it can be a lifesaver when things go sideways.
Considering it doesn't make any difference in the real world and only leads to higher consumption, I'd have to say no-one at that cost. Sorry for thinking critically... I have that nasty habit.
A network of approved Joe and Bus Grease Monkey machine shops is needed for this community.
Hi Nice job on the injector tubes, super that you got the tools to do them right, shops are obviously not up to the job, Lenny ran so much smoother after Joe set them right, and now you can do the same, a good old handmade thumbs up.
Good thing the machine shop rebuilt the heads so you could rebuild the heads too.

Lateef Carrere well said brother, well said!!
I'll second the plywood over the dirt. Done it a few times myself, makes a huge difference.
Your knowledge is fascinating. Keep the videos coming!
Back in the last century I had a valve job done on a slant six and after the machining they put it in the hot tank. There was so much sludge in the ports I had to disassemble everything! Crap work has always been around.
Paintnamer It’s worse now because machine shops are few and far between and are so backed up with work. They can’t find quality help either.
They probably oiled the heads to prevent rust and the shop had some grinding or polishing dust floating around, and attached to the wet surface.
Good job! 👍👍👍👍👍👍

100% that's a big price for an infinished cylinder head.
Scott, you should consider investing in a lightweight enclosed trailer that you can pull behind the bus and work out of.
Plywood will help with the cherry picker.
I wouldn't be happy if my stuff came back dirty, the paint looks like Navistar green lol

I second that, good ide to check before rather than repair later.
BGM,
Good idea random checking machine shop work. I’m sure you have not forgotten your experience with poor workmanship on Lenny’s four valve head.
That head doesn't just have 'dirt' on it, it's more residual machining grinding / polishing compound, right? Wouldn't that be a huge bearing wear issue once it gets into the oil??

@@marcwoodward850 they sure did a piss poor job. Scott had to practically re-rebuild both of them. Prominent doesn't always equal good!
These machine shop people are really dropping the ball. Must be NO qualified shops anymore. It's a shame.

Pretty grimy machine work , seems like a quality machine shop is hard to find . Lost trade.
Sorry but that's the economy these days. The price doesnt warrant quality, gotta pay the rent and taxes
@@Alex-vb8kq the price doesn't warrant quality????? - they paid $1500!! Good grief, Charlie Brown!

Lay down a sheet of plywood
Well, it pays sometimes to go by detail... Some get upset but what do we know!
Hi, suppose machine shop were not impressed you sent them dirty heads.
