Mercedes Diesel Engine Transplant: Digby's OM617 Gets a Make Over for Christmas

[@dustinroberts795]

I took an ASE certification test recently, one of the questions was regarding an engine with low compression and no leakdown. I knew it was a bent rod, thanks Digby and guys!

[@blackbird8632]

Love to see you guys together, great father son time!

[@gtoger]

You guys are making me second-guess my plan to just toss my junkyard motor in my project car. For that I both thank and curse you. Looking forward to seeing Digby ride again.

[@lelisortiz8557]

It is great to watch father and son working together! Thanks for making these great videos. I have been restoring 2 190e and your videos had saved me multiple times when I could not find a solution, I am not a mechanic, I am lawyer and pilot, but I can fix anything with the right tools and instructions and in this case with the right youtube videos. Have a great day!

[@carsten4594]

Thanks to Ken's video and subsequent kit I was able to stop a long time leak which I had attributed to a leaking rear main seal. 😊

[@sarahs5340]

You guys are so amazing. Thanks for taking the time to do these videos. Really enjoying it. P.s, please don’t forget to show us the up-dates and refurbishing you do on the interior too.

[@dr.orlandoperez6763]

This was fun to watch and very informative. Thank you both. I have watched you dad do these for years and I'm so glad your with him to help. Best regards to you both. Oh, I'll like to buy this car when she is done. Hope you thing of me. Thank you Orlando

[@steffendhonau]

Love your channel, I'm from Germany watching digby episodes helped me a lot fixing issues on my 1987 w201

[@RR98guy]

Thanks for the Digby Video. Merry Christmas, Kent, Joel.and everyone else watching!

[@miguelstingray]

Simply, thank you. The knowledge being taugh here apply to any diesel.

[@backwoodsbungalow9674]

Very useful summary of the maintenance to do while the engine is out of the car; thanks for taking the time to share your experience. 🙂

[@davidhutchison3343]

Rubber seals in old engines are guaranteed to be hard and cracked, so makes sense to replace them whilst the engine is out, and everything is easier to get too.

[@arnhemseptember2009]

Always great fun to see you 2 work together!

[@robsambucca]

love your MB education from down under with a leaky 95 c220

[@caddydaddy84]

I couldn't wait to get home to watch this. Thanks so much!

[@dh7277]

great series... from professor Kent at Mercedes University !

[@darren-thecottageatelier8962]

I was just wondering how Digby's engine was doing, and out came another great video, and now I am intrigued about the transmission given the history of this great Digby series. Fantastic work guys keep it up and Happy Holidays as you say over there..

[@fredflintstone8048]

Lot's of great pointers. Thank you for sharing.

[@malcolmscott4150]

Great work you two - go Digby 🥳

[@Genecaster]

I keep looking at that M104 in the background and it reminds me I have a M104 in my basement needing some TLC :D

[@depocars]

You are great Family , Im really respect u!

[@andrewwmacfadyen6958]

The wax thermostats used in cars as they age gradually tend to open at a lower temperature. For good heat in the cabin especially on diesels renewing the thermostat is a really good idea.

[@CarDocBabaPhilipo]

Awesome complete quality job guys :)!!!!!

[@deniscudahy4549]

Merry Christmas all the best for 2020 look forward to more of Digby

[@baden-baden]

Great channel, I love Mercedes w126 and w123 OM617 engines. Thanks

[@thethirdgeneration1738]

Question, why the decision to go with a w126 into Digby? Is there an advantage for doing that? And, wihich is considered the better engine ? Just wondering?

[@iivaridark6850]

Having a good time with an old car does good for your health! At least if you don't get aggravated too much...

[@mikeholbrook5084]

OK, you kinda let the cat outta the bag when you said the words "new owner". I'd like that to be me of course as I'm sure your 216k subscribers would as well. How about giving Digby away on the show or raffle Digby off. Let us know where the line is to be the future owner. I remember about 15 years ago working on my 83 300TD using your fixes and tricks to keep old yeller on the road. Unfortunately I let her get away but the chance to own a Mercedessource 123 would be worth Digby's weight in gold. Awesome series. Thanks.

[@dymsza]

O wow :) Looking forward I have problem with pump right now.

[@domino-ve6ei]

You guys are my hero!

[@timmills9727]

Great stuff!

[@mds2465]

I agree with all of that stuff. When the engine is out of the car replace everything and anything that is broken, leaking, or prone to leaking overtime. That includes any and all gaskets, seals, plugs, hoses, etc. In this case of a manual transmission it’s a very good idea to go ahead and replace the clutch in that situation but since this is a turbo diesel those were only made in automatic anyways at least here in the states. The only car that I know of that has a clutch mounted on the outside of the transmission is a Ferrari and I think that’s only certain years and models. It literally takes about 15 minutes to replace a clutch on those cars. Rear main seal is another important thing to replace. As for the a/c I might replace the hoses and pressure lines but charging it would be difficult in the wintertime anyways so I understand why you might not wanna do that now.

[@gbattilanaf]

I so want a diesel W123, too bad that the few examples we have here in Peru are in very rough shape :(

[@obelic71]

not only in peru they were driven in to the ground worldwide. Most famous is the taxi cab / commercial version in Europe. Those versions had special reinforcments for an extra hard working life. There is one such service estate W123 ( no rear seats ) from a MB truck dealer who bought it new in 1981 who has reached 2.5 million Kilometers with the original engine! The entire car is total worn out and put on display at the dealership. It still runs. There are plans to restore the car to new for the 75 year celibration of the dealership in 2021

[@TheDynarc]

Tack från Sweden...

[@mattm8641]

I think that I'm the one who pointed out the check valve replacement in a recent email...just make sure you clean that old gasket off..its a bad oil leak spot.

[@EndofUSA]

I hope Kent can give some advise or answer as to why my 300SD 85 after a long trip starts to shake like a paint shaker. She has been running well the past few years only lately she started to act up as her idling suddenly changes its beat!!! Has this something to do with the injection pump or injectors!!!

[@COMM114]

Excellent progress. Can you comment on parts availability and cost for these engines? What sources do you use? Do you ever go to Germany to scrounge for parts? Would love to know.

[@Mercedessource]

Hundreds of parts, kits and repair manuals available here: mercedessource.com/store/search?keys=diesel%20engine

[@anthonysimmons1673]

Enjoyed!!!

[@avivscrewvalla]

Finally, a lift pump kit! Will this fit all styles of OM61X motors? 2 bolt and 3 bolt?

[@davewhipple4815]

What about the Trap oxidizer? Something I can by pass?

[@sepresley1]

i had a wore out 300sd....man i sure do miss that car.

[@leongailberger7676]

Just a little question, my 240D has good compression, the glow plugs are working but it is a little bit rough in idle and its not starting that well when it is cold, how do i clean up the pre chambers?

[@Mercedessource]

With hard starting issues you always start with a compression test first after doing a valve adjustment on diesels up to 1985. If compression is ok you move on to glow plugs, carbon reaming, filters, lift pump, fuel injectors, and injection pump timing.

[@coolguybrar]

How much this engine weight?

[@isbcornbinder]

This is an important video. I hope Joel is OK. There is that lump on the back of his head.

[@honestguy7764]

Getting to It

[@dymsza]

when the lift pump kit will be in store ?

[@Mercedessource]

By Christmas...

[@mattm8641]

I want to do my injectors but I keep spending all my money on suspension issues...my car 300sd has +300k miles on it...those injectors most need service!!

[@northwest8634]

Sehr gut!

[@joeyscleaninglady2877]

where is jureston?

[@Mercedessource]

His name is Gerson and he is welding wrenches and building injector testers.

[@12namleht]

Digby!!!

[@joeclarke9782]

Wait a minute. That 126 is looking good. Maybe backup and refill that W126 engine bay. Sorry Digby.

[@Mercedessource]

That was just a reference image. That 300SD only has 156,000 miles on it

[@mitch300sdl]

Who thumbs down these videos?

[@pvman2]

Another thing to do while the engine is out of the car is to clean the exterior.

[@tech333tex5]

Hi I have this car I came across for $600 I know it's a long shot but by the sound of the engine on this video can you more or less tell me anything on this .? What to look for what to check ... I'm wanting the motor and transmission for a project... Thanks any feedback from this video is greatly appreciated. Thanks I've sent a video please check it out and please comment on your opinion of this sounding engine.
