When I went to buy a tow pig, everyone told me those stock 6.2's are great motors if you don't exceed their limits or hotrod them. It's great to see Mojo at work, not just background noise.

[@RiffRaff160]

You can learn from books, video's etc, but nothing better than listening and watching a old school guy show you how it's done. Wealth of experience and information. Priceless 👌

[@MortskeRepair]

Having Mojo is like having every repair manual from 1958 to present day . WOW , he is amazing !

[@MortskeRepair]

sure is!

[@shanehansen2141]

This is one of my favourite Mortske episodes. I could listen to old mechanics like Mojo for hours. I know at the beginning he didn't want to be on camera at all but hopefully there's more like these.

[@bigchevy350boy]

Always good to see the old timers work on these rigs! Was cool to see! Also.. I've NEVER seen this topside creeper! Kinda cool!

[@drive42]

You might consider using a rubber tipped air nozzle and shoot air into the glow plug hole on each cylinder to see where the air is going. That would tell you whether the head gasket is bad. A 6.2/6.5 is an indirect injection system, meaning the injector sprays fuel into a pre-chamber instead of right on top of the piston. The glow plug heats the prechamber, which gets the fuel to ignite and start the engine. This is also why the glow plugs are needed year round. Going back to the beginning of the video, the previous owner said the engine was locked up. Perhaps it was hydro-locked from coolant entering the combustion chamber from a blown head gasket. In the time the engine sat, the coolant seeped by the rings and let the engine spin. The 6.2/6.5 diesel wasn't a bad engine as long as they were not overloaded, had good glow plugs, and clean fuel. We had one in a 1 ton 4WD we used to pull around a tub grinder, which was WAY too much weight. After replacing a couple engines, we bought a GMC Brigadier with a L-10 Cummins, problem solved. The other 6.2s we had that weren't abused were pretty dependable. I still would't want one, though.... Great video! Mojo kind of reminds me of my 91 year old Dad, who up until a couple years ago was still tinkering on things.

[@MortskeRepair]

Thanks for the tips

[@mattaker896]

Mojo sure is a treasure! Watching you two reminded me of all the junque my dad and I used to work on. These days all we work on together are reruns of Gunsmoke and a few beers.

Totally enjoy the interactions you have with ole mojo. The friendship you two have is priceless! Mojo is a library of knowledge that you are blessed with having. Everybody should have a mojo in their lives. I think you are pudden's mojo.

So true!

[@stevelangston2359]

Mechanics like Mojo are a passing breed. Just try to find anyone ( yourself included) that knows so much keeps at it, and won’t stop till he gets it done.

[@MortskeRepair]

he's a real asset!

[@steveperyer4850]

Always and added start to my week with a Monday morning start with Sir Mortske, and MOJO showing the kid how it’s done on them diesels. Great start to my week! Maybe Puddin, will finally be working on cars again, instead of cleaning his new digs, and junk yard searching in the high grasses.😊

[@hanknipper3921]

That’s a bummer that Duff didn’t get a ride but he does love running around! Great video and you should give Mojo a raise

[@MortskeRepair]

We will!

[@johnelliott7375]

He probably knows more service manuals by heart than most genius engineers forgot about.

[@bjjnut5777]

Always dig your videos, but this one was endearing. Your friend Mojo reminded me of working on tractors back home with my grandfather a very long time ago. Thank you for making this and for the good memories. Stay well.

[@derbymankg]

It didn't run, that's ok. You ventured in to the world of the 6.2 AND we got to see a great Mojo video. Men like him are irreplaceable, and full of incredible knowledge. Great video as always, Thank you!!!

Well said!

[@stevenlatham4397]

6.2’s were way better than the 6.5’s. I’ve had a few 6.2’s that made it over 300k. With modern diesel fuel lacking lubricity, adding used motor oil helps them tremendously. Yes, they were absolutely gutless, but they did get excellent fuel mileage. Manual transmissions behind them is rare. I just recently got rid of a ‘93 GMC Z71 that was a 5 speed. It got 24mpg. I only got rid of it because I couldn’t find a harmonic balancer.

[@richbrockmeier3922]

You're one of the few channels that I'll watch Repeats. That's fine praise for you, Thomas. Thanks!

[@DangerousSportsForSeniors]

You just knew when Mojo got over being camera shy that he was going to be a star. Thanks again for all the hard work.

[@markgerdes3402]

before pulling the pump the next time, remove the return line fitting on top of pump. check ball inside plugs up with material from inside the pump. it will start and run . the local chevy dealer and i took his demo, an 85 suburban with a 6.2 and 700r4. 3.42 rear, on a ski trip from west texas to colorado, and averaged 28 mpg loaded with people and gear. diesel was under 1 dollar / gallon.

Usually pulling and installing new head gaskets will tell you more about the condition of the engine Block and heads. I'm sure injectors need to be taken apart and cleaned if the cylinder and heads are in good condition.

[@Jacksonkellyfreak]

After a long day I finally got back to finish the video. What kills 6.2s is cracked main webbing and broken cranks. It'll either fly apart or lock up. Also I see you learned the lesson of never shooting ether onto hot glow plugs haha. Fortunately it was just an open hole, but it can blow intakes apart or on some of the Ford idi engines blow the injector cup out

[@iHap]

We’ve all been there, Mort-fighting with a motor we want to run, but just does not have the juice anymore. Working along with you and Mojo and Duff Dog supervising was still a treat. Thanks, Mort! Love the Duff!

[@faulknerfixesall]

thanx for the shout out mortske-I knew you were going to need several batteries to get a 5.7 gm diesel to run.funny how the the gm diesel with the worst reputation actually ran. keep the great videos coming.

[@MortskeRepair]

Much appreciated

[@stephanieluigon5192]

So true! The gasoline based 5.7 Olds diesel "unreliability" (read "horrible idea") did more to harm passenger car diesel sales in the US than cold weather start performance or lack of support. Expecting a gasoline engine to withstand the necessary compression ratios of diesel engines showed the silliness that made GM eventually file for bankruptcy.

[@faulknerfixesall]

@@stephanieluigon5192 i totally agree the engine block on the diesel 5.7 is just an ordinary gas engine block-what were they thinking?one redeeming quality was if you had one in california and you registered before the eventuall gas engine conversion it was smog exempt -but what a lot of work to drive a giant gm car that would be smog exempt

[@larryd.214]

Thanks for another good one Mr. Mortske! Great to see you and Mojo working together on that ol' 6.2.

[@MortskeRepair]

Our pleasure!

[@amadeo_serrano]

I often wonder if Deutz had the right idea when it came to preheating the F8L series diesels. Rather than a set of glow plugs, they used, essentially, fire to preheat the intake air. They had jets in the intake tubes that shot a flame in each tube to preheat the air and, in turn, the engine. Very effective providing you didn't use ether and blow out the intake tubes.

[@michiganbushcraft975]

It was great watching you work it with Mojo. That's an OG mechanic right there!

[@badger_valley_customs]

Pretty sure the timing chain jumped, that’s why it doesn’t have compression. Can hear all the compression coming out the intake valves. Enjoy the videos even when there’s failures, we all get stumped sometimes and chase down the wrong rabbit hole once and a while. Except Duff, he knew what rabbit hole you needed to go down, just couldn’t explain it. Haha!

[@kolt.45]

To add to your timing diagnosis, could the injection pump timing be 180 out? When they were turning crank to align dowel pin it would have to be two crank rotations to one injection pump rotation. It appeared they only did one rotation.

[@dans_Learning_Curve]

​@@kolt.45should have at least fired on starting fluid.

[@TestECull]

@@dans_Learning_Curve It did. Coughed, spat a fireball, occasionally kicked over half a rotation.

Mojo teaching Mortske to repair diesels, what a cool combo. I'm sure the reason why it was said the engine is sized might have been to do with all the bad ground cables what where not hooked properly or a very weak battery. Too bad the engine was pooched, probably got used and abused.

[@netrioter]

A 6.2 Detroit. The main downfall of them is they were designed to be ran extremely hard..not light use, they get carboned up too easy...and will not start in the winter. Gotta hand it to GM though, they were the only company to make diesels in-house until just recently. It made the trucks way more affordable vs. Ford or Dodge

[@joeyjackson1160]

Mojo is just greatness!! His “well yea” love it so much. He just stays so calm. It’s awesome when he is in the videos too

[@MortskeRepair]

Couldn't agree more!

[@RustyDreamsGarage]

Upgrading to 2/0 battery cables will solve the wires overheating (common issue). Never use starting fluid on the 6.2, wd40 works great. Cycle the glow plugs for 30 seconds for a couple rounds. I have some crappy videos on my page for the 6.2 referencing all the above issues.

[@grabasandwich]

Junkyard Digs recently posted a video of one with a 5.7 that they swapped with a 455 gasser. A while before that, they were in the background of Pole Barn Garage's video unsuccessfully trying to get it to run. They're turds, but there's a small group of people who love these GM V6 & V8s and still want the parts. Apparently the DX blocks are more desirable, but I'd imagine in a few more years parts will be unobtainium.

Man mojo loves those six twos as much as I love the 7400 vortec although I'm sure he's probably forgotten more about the 6-2 then I know about a 7400 vortec got to respect the experience ps. I'm almost to the end of the video now it's something that I learned while working on a 7-3 with a good buddy of mine The older diesels really don't like either very much what you can do instead that works really good is soak a rag and gasoline and choke the engine with the rag it has the same effect as either but works a hundred times better on those old diesels
