Prevost Detroit diesel 92 series needs a rear main seal.

Customer set up an appointment to replace the rear main seal on his detroit diesel 6v92TA in his Prevost.
Luck was on his side on this one! A simple diagnosis of a different problem saves him many thousands of dollars on his bill.

This gentleman is fortunate to find a honest and knowledgeable shop. Way to go BGM.

[@daveogarf]

I second that. Thanks, BGM & crew!

[@gwharton68]

The owner sure brought that coach to the right shop for repair. He or she should play the lottery.

[@t2k777]

your honesty is refreshing, very few honest business people

[@DavidLasyone-jo4zv]

That's the difference between looking for the problem and looking for money. Once again, good work guys!

[@robertash883]

Good, HONEST Mechanics and Shops are the hardest thing on the Earth to find!

[@18robsmith]

Some shops would have charged for the rear main seal job, ignored the filter and the customer would still have the leak. Scott says "This doesn't look like the rear main seal", finds the leaking filter bowl, fixes that, save the customer a lot of money and has another happy customer.

[@billmoran3812]

I think most shops would have taken his money on this. It’s rare to find a place that is competent and honest.

[@aussiebloke609]

I'm sure the owner - and us viewers - appreciate your honesty. There's so many workshops out there that will happily perform work (usually poorly) that isn't actually needed if they can get away with it, and especially if it's a lucrative job like a rear main seal. Cheers! 👍

[@GarryFishermusic]

Looks like Christmas and his birthday showed up unexpectedly.

[@h5mind373]

I love the size and simplicity of a 35' Prevost. Short enough to get him into almost all of the national parks, too!

[@dalemettee1147]

Can you imagine what a questionable would have done with this coach? An arm and leg to fix a simple filter leak not to mention not even replacing the filter.. Good job guys!

[@craigroberson8757]

Sure does my heart good to see honest mechanics. I am glad you were able to get him going without having to have an armored car to bring the money to pay the bill..

[@robertborchert932]

Great finds, so fortunate for your customer expecting a power train removal. It’s a pretty cool slide out on the Prevost chassis. The hard part is all of the ancillary plumbing, none of that is standard after many years, and you ALWAYS find knackered hoses. Right? Seeing your operation always makes me smile! That pit is sure handy, especially under Prevost. I grunt at leveling valves, they don’t last like they used to.

[@timwatson3879]

..that pit was one of your best and lowest cost investments!

[@philobresil6152]

Big smile when you expect to have a expensive repair and you get the news from a honest shop. Good job , again.

[@jamiesuejeffery]

The charter coach company I worked for in the mid-1990's had a few 6V-92's still hanging around (most of the coaches were running 60 Series). We just called the 6Vs, "Driptoits."

[@SimmyMetal]

If it ain't losing oil, it's ain't 'troit 😆

[@mfc4591]

I have always remembered wise words told to me....always look for the simple fixes first. Well done men.

[@chele-chele]

An honest mechanic is assured a seat on the bus to heaven =)

[@elmercoffmans4223]

Just think if you were like a lot of these shops you could have stuck it to this guy bet he is real glad he came to you 👍

[@mischef18]

Bet the owner almost gave you a cuddle finding out it was not what he had feared bro. Safe travels. Ken.

[@rubeng3091]

Great job! People like you will be blessed with great success!

[@lyfordmerrow6332]

I love the colors on this bus!!

[@Vile-Flesh]

Nicely done. That Prevost looks like a nice sized travel rig too.

[@jerrykinnin7941]

Wish my T880 would stay aired up for 5 days. Great catch on the oil filter.

[@louk231]

Wow, the owner must be smiling broadly. Great diagnosis guys...

[@mistero4]

You’ve got to love when a job ends up like this. I’d say they’ll be back.

[@marinablueGS]

Bet that owner was happy. It's not often that the maintenance repair is less than anticipated.

[@kennyrodg]

Nice ! What a great outcome

[@dont-want-no-wrench]

that must be a happy happy bus owner

[@tomandpeg4818]

Great job for the customer and your reputation.

[@galegregory97comcast]

Your pit is paying for it's self ❤❤❤❤ it made it a easy fix I guess

[@mowguy1]

Great that it was fairly simple fixes. Im sure the owner is a huge fan of your shop.

[@lloydrobinson7081]

keep the clips coming

[@wernerdanler2742]

Well, that guy sure dodged a bullet. You know if he had taken it anywhere else, they would have pulled the engine and done the main seal, and after a 10+ grand bill, he would have still had the leak. 😮

[@throttlebottle5906]

they wouldn't have changed it, pressure washed and wrenched all the bolts/nuts to look like it was done, fixed the filter and charged that much !

[@frankgtrucks200]

I love that size coach....hard to find in decent condition.

[@DanT271]

Nice the owner sure dodged a bullet with the oil filter leak

[@creativeloafer9792]

Good work fellas!!! Fantastic diagnostic skills!

[@anandarochisha]

I used to have a couple 35 ft highway buses. The usual maintenance plus a rebuild on one. I think a Chev P30 chassis RV might be the way to go after owning buses for 15 yrs. The main seal is enough to replace a 454 big block with a Cummins 5.7. Twice the mileage of an 8cyl 2 stroke Detroit and if a rear main seal blows likely only an afternoon in a shop with a pit to replace it by lowering the tyranny. I dunno. Nothing like the feeling of sleeping at night in a steel lock box though.

[@RollinHomies]

Some day I’ll make it to the “Dirt Mountain Top” and get some work done on our Eagle✌🏼

[@LORFCASTER]

Legendary save Honor points gained

[@eddiereichel9354]

I never replace parts on a customer car without first doing my own diagnostic. The dude said hopefully it fixes it. I can tell you that even garages and dealerships sometimes don't know what they are are doing. Had a Ford escape at my shop. Customer took it to ford dealer for a recall unrelated. The left front abs sensor wire broken. They told customer 400 to fix it. They agreed. The dealer tech went to abs module and cut right front wire and wires left front sensor to it. He then cut the new wires and flip flopped.them 3 times trying to get left front abs input. They told the customer they needed new abs module 2500 plus 1000 labor. They told him he could not replace it with used. He called me and I asked him if he wanted it replaced or if he wanted the issue figured out because that's 2 different things. When he came to get it replaced I found the actual issue.

[@moosibou]

Hmmm, I recognize that bus. Used to belong to a fellow in MN.

[@DLTJR1959]

Real mechanic. BGM is a real mechanic.

[@edwardantrobusjr2253]

I see a lot of comments about how lucky the owner is. While that is true, he chose the right mechanic. That wasn't luck. Scott & Jonathan are the lucky ones. The rear main seal would not have been a serious pain. And still wouldn't have fixed the problem. 😊

[@michelbrodeur6055]

Wow from a estimated repair of $7000.00 to less than an estimated repair of $700.00ish. Way to go Scott keep up the good work at Bus Grease Mountain featuring the Bus Grease Monkey.

[@coniow]

I reckon he wants to buy a couple of Lottery Tickets. His luck is Surely in!

[@mojo68mitch]

very nice. sure saved that guy from the wolves.

[@robertgriffin7569]

You guys are the best... ✌️❤️😁

[@sha1om]

I have a 1988 S10 Blazer with the factory armor plating, which had that exact problem; the oil filter is remotely located from the engine because there's no room between the bottom of the block and the shield plate. The gasket where the remote mount hose attaches to the block (where the filter normally would be) was worn out, and was dripping oil only when the engine was on.

[@isaacsims6203]

🙂Good catch youguys good catch

[@jamesford7182]

Detroit told us one of the test engines in the 92 series did a million miles in over the road work and there was hardly any indication that the rings had even a ridge at the end of the cylinder bore. It was widely adopted in many industries and ours (fire apparatus) and proved to be a true workhorse. In fact, it was so well loved there were even enterprising small companies that built stainless steel rectangular pans about an inch deep that were strategically located in fire apparatus bays for trucks to park over. But damn, those things can work. Haven you ever been next to a truck that can take water from 10 feet below it from a pond and make it pump 1500 gallons a minute to a distance of 200' then through a nozzle at 150 psi for a full two hours? And then take it to 200 psi for another hour and, yet again ramp it up to 250 psi for another hour. Just walking around the apparatus while being tested is surprising at first. Those trucks howled and delivered. The 8v92 with an Allison HT740D transmission was my favorite combination for large scale trucks. You could be driving a 48', three axle truck weighing 70,000 pounds and it would drive through traffic like a car. I am guessing that 6V94TA makes that RV drive like a charm.

[@malcolmyoung7866]

Happy client… That oil filter was flopping around something chronic.. would have thought it would have been secured better?

[@rutledgefuller2668]

Excellent job.

[@safetyvideos9866]

We're getting a new main seal put on an A14NET engine in a Buick Encore with 140k on it. We also had to replace an air conditioning hose. Next I fear the turbo might go (the turbo is quite susceptible to housing cracks).

[@uliwehner]

How rare is 35ft liberty coach? Would love to see the inside.

[@reginaldbyrd8073]

Nice beautiful.

[@5695q]

I imagine you were not looking forward to pulling the whole powertrain, so finding it was just a leaking filter was a relief. The owners wallet probably sighed with relief also, by chance did you look at the coolant drip while you were under the bus?

[@carlaustin7398]

I'll bet that bus owner wanted to kiss you right on the lips. 😅

[@josephalberta1145]

I am not sure about the older Prevosts but on the newer ones and not so new ones the whole engine slides out on a cradle.

[@timf6916]

Nice

[@richardjulien8745]

I think all he need now is a good pressure wash in the engine compartment.to maked clean.

[@petetibbs6103]

I would say that “if I ever get my 4104 on the road you are the first place I will go” but I’m afraid you will tell me the truth and scrap it on sight. LOL

[@pigpen3499]

He better had left a tip...

[@pcspecialistpdx]

This is where I joke again that it isn't a rear main seal when the engine is oriented in the engine bay such that the rear is in front.

[@jackkreighbaum783]

I know it is counter to a mechanic's income, but have you tried AT-205 Re-seal to rejuvinate seals?

[@eddiereichel9354]

Soap will not bubble with holes over .005. berine Thompson from ats did a video on it.

[@BusGreaseMonkey]

But you can hear it and see the soapy water being blown away from the larger opening leaks

[@eddiereichel9354]

Oh for sure. I have been using bubbles for years for all kinds of leaks. I thought that it showed all leaks not just small leaks until I watches that video. He had done some semi scientific experiments with hole size and bubbling ​@@BusGreaseMonkey

[@throttlebottle5906]

it will, but just as the pressure and flow volume reaches near zero. think gently blowing through a straw, hose or bubble wand.

[@ChrisHarding-lk3jj]

I would have replaced that entire obsolete oil filter housing with something more modern.

[@palominomale]

The spin-ons are nice but nothing beats the durability of those old steel cans with sock elements messy though they can be.

[@tomscorner3656]

You want it done right, see the Bus Grease Monkey.

[@SHX164]

Is that a nut missing on the rear airbag at 1:20?

[@BusGreaseMonkey]

Yes

[@mrad6533]

Any other mechanic would have charge a ton of money and fix everything that didn't need fixing

[@anandarochisha]

Sure is pretty..

[@jeffcooper5789]

Got off very cheap.

[@bextar6365]

Use JB Weld to seal the leak .

[@kriswright1022]

I hope yer being sarcastic! 😂

[@GNX157]

I don’t understand why as an owner, you wouldn’t power wash, steam clean, whatever, that engine, multiple times and, A have it clean(er) for the shop, and B also to try and narrow it down for yourself before taking it in. And on top of that to not tell the shop what it is, just that you think it MAY be whatever, but you’re not sure, and ask them to diagnose it.

[@h5mind373]

Not everyone is handy; that's why we have Bus Grease Monkeys.

[@timwatson3879]

...but, not everyone diagnosing issues is you...any other place would have not put the extra time to find the correct issue and charged them for a new rear main seal...because they can.... not only to you save lives by finding "discrepancies" with other shops work, but you are making video recordings of your findings as proof... no wonder everyone is now coming to you, unlike a few years ago, when you drove to everyone...
