How Was This 50 YEAR OLD ENGINE Even Running!? Mercedes Marine Diesel Rebuild 2 | Wildlings Sailing 

Enjoy this time with your dad! What a dream come true for him to get to have this time with you doing what you both clearly enjoy!

Rebuilding your engine 1500 pounds. Working with your dad on the engine rebuild priceless.

Two items missed from your list... Firstly core plugs, always worth replacing if you are rebuilding an old engine. Secondly, beers for your dad. He's a star!

My 2 cents: let all those grimy parts soak in diesel fuel for some time and brush. It will dislodge all the crap in crevices and surfaces. Then, a dregreaser wash and pressure rinse. BTW, it's a miracle that this engine even started with all those blocked solid passages ! 😳 You should consider acid clean and flush the coolant passages through the block and (?) head. They may be blocked by rust which could explain the overheating problems...

Dad must of sponsored this vlog again😄😄keep up the good work most interesting

You are very lucky to have a generous dad who gives you so much time. I would like to bet he's enjoying this time with both you and your shoddy engine.

You have my sympathy with that old diesel. Been there done that! You’re paying cheap money for a fine education. Your dad is priceless. Put some gloves on (note your dad wears them) before your hands resemble 60 grit filthy sandpaper. I’m relieved to see you’re no longer botching. You are becoming a craftsman.

I like Dad’s workshop, especially the pony car sitting there.

Tapping the nut to reform the thread. Priceless knowledge. Thank you all very much for being able to follow along.

Beautiful 1969 mustang! Great job you and your dad are doing, Mark.

I rebuilt 4 or 5 engines in my younger years. Watching you work on this engine brought back a lot of memories for me. You dad certainly knows what he is doing. Cheers.

Good oll dad, you're a very lucky young fella to have such a dad.

Hi, I enjoy watching your videos. I am from the Czech Republic and I really like your trip in a catamaran with a dog. I wish you that you will be able to put the engine in great condition and I greet everyone and Dad. Milan from Přerov CZ.

KEEP YER CHIN UP....YOU BOTH ARE DOING A GREAT JOB , AND WITH YER DAD HELPING, IT SHOWS HOW MUCH HE LOVES YOU BOTH AND YOUR WONDERFUL CAT, OH AND LET'S NOT FORGET ABOUT LITTLE " YOSHI"...

Your father is a big help for you, I am a retired Mechanical Fitter and worked on engines as well. First one was in a 25 tonne diesel locomotive and later stripped and rebuilt a Datsun 240 engine. Thank you, , Wim, Australia

Looking good so far Mark. How lucky are you having a dad like that and I Beth mum looks after you when you go home.

Elbow grease is inflation-proof. Great project. You have a super Father. God Bless.

Your Dad's shop is legend.

Mending what you've already got is a great way to go if you can. You're lucky to have your dad's garage and his help and I've no doubt you'll look back on this as time and money well spent. Great work.

Here in the states we would take the stripped down block and head off to hot tank it to clean out the oil and water passages. It's a good thing your dad is supervising this rebuild, I bet he's enjoying himself.

You're dad needs a parts washer, and a sand blaster, and those little briskets with the penguin biscuits that never seem to go empty next to the perpetual tea maker. Great Video mate.

Definitely have an expert go through the fuel injector pump. That is the most technically complex component in diesel engine. FAR more complex than a carburetor. Great video, as always.

There is an old saying I haven't heard for ages "Knowing the price of everything and the value of nothing." Well, you're paying the price for everything on land, but the value at sea will be beyond measure 😜

Pro tip. Take a plank and drill 8 holes and number them, and put the valves in them. Set some 75-100 mm nails in the plank, and let them store the springs etc.

your dad has got the mecanical magical touch when he taps on the stud.

What a wonderful family project and I'm glad it's going well

Additional parts I did not see listed. Head Gasket (not the same as a manifold gasket), Main bearings (for the crank shaft), Piston bearings (for the piston rods) - these are almost a must to replace since you have the engine broken down already. Have someone look at the fuel injector pump and the oil pump just to make sure they are in full working order. Cheaper now than later.

Enjoy the way you tell us the cost, would have no idea otherwise. All good information.

Please change the springs, also sand blast and paint we would love to see that motor not only in good working conditions but beautiful!

I have no useful knowledge of motors, but I found this video very engrossing. Can't wait to see it put back together! Also, you're dad rocks!

My fiirst car my father bought me didn’t run. At 14. What he did was taught me how to pull heads. And at 16 grades were not good enough he sold it a good running car. But today and many rebuilds later you can do it thank you father.

Liked the double nut chapping tip from Steve, great to see the full rebuild of the engine, peace of mind come sail time.

Never Give Up...So Love You Guys. Much respect To Your Father.

I think you made the right call, best of all you let the expert make the call on honing over boring.

Enjoying this immensely. From Indonesia. Hey sail your boat here! You both would both love it.

A reliable engine is a must. Breakdown on the A13 to Romford, you call Green Flag. Break down with no wind, (or lose a rig/sails in a storm) who's going to tow you in?

Another great video

Great dad you got there to

One day it’s finished ! You will have a perfect boat ! ...for a perfect journey ! We live on a sailboat too. Good luck ! ⛵️👍

Main bearings. Crank check size and repolish if OK. Check cam/followers and bearings. Check rocker arm bushes. Reface rockers. Check all push rods are straight. Proper reassembly lube. I'm sure I've missed lots. The small seals on the valves are there as a first stopper for oil running down the valve stems. Replace. The big seals have to be serious stuff as a diesel has very high compression, hence more suck. Use quality gaskets. Did you look at Yaba's engine rebuild?

Where have those two nervous young people gone sailing from that marina In Wales. Well done so far.🇬🇧🇦🇺

So satisfying to see those dirty parts get cleaned!

Fine for the engine tour. How about a closer look at the mustang in the background! Lol. And very curious on what’s hiding under the car cover. (Corvette? ) And the comments you got about time spent with with your dad- priceless.

You should be very proud of yourself. The video was very will done. The way you keep everyone up to date. The engine truly needed all the work your putting into it. The knowledge you have picked up along the way really shows. Great job!!!!!

Excellent episode Mark, very informative and great insight. Thank the lord for "Dads"!

Very nice to watch the engine teardown, and I always like to know what things cost so thanks for both of those things. Best to you guys. I'm cheering for you!

Absolutely brilliant video mate well done proper getting on with it !!

You and your Dad are amazing, Nadiana too. Love your work ethics. As I know as much about engines as a gnat I am hoping you don't forget how to put it all back together. Looks like one heck of a puzzle to me

How Was This 50 YEAR OLD ENGINE Even Running!? That's what diesel engines do. They rumble and grunt for hundreds of hours, often neglected, consuming ever increasing amounts of fuel and lubricating oil until the final gasp, as did this engine. Once refurbished, it will once again provide the vital auxcillary power needed by a primarily rag-powered boat. Another thoroughly enjoyable episode in the Minke saga. Thanks for posting Mark🥰.

It's always a temptation to do it the most inexpensive way possible, but that always ends up costing you an enormous amount in little time. Good video, and great good luck.

Dear Nadiyana & Mark, In this vlog we learned that Mark seems to have more technical skills than we thought so hopefully he’ll be able to rebuild the engine with the same speed as he did dismantle the engine engine but than working as it was before but than like a new running engine. We wish you both both lots of success with the the refit of Minky and send you ❤️ from the Netherlands. Best regards, Willeke and Dick de Graaff

The "valve lickers" that we used to call them, the rubber gaskets that will stop oil being sucked into the combustion chamber from the top, was a well known problem with the early Ford 1,6 and 2 litres gas engine. When you reached about 100K km driven, you had to change them because the motor was burning a lot of oil. I did 2 motors, first on my Ford Taunus 2,0 GXL and a bit later on the Ford Granada 2,0 GL I got a bit later. I got very savvy on those engines, after changing those, timing belts, starters, overhead cam shaft and lots more.

I don’t know much about Diesel engines so watching you all taking these small diesels apart and rebuilding them is really interesting. Great video. Thanks for sharing.

Looks like it's going well, being transparent with the costs isn't a bad thing.

Dear Wildlings Sailing family. 👍👌👏 Congrats! Looks better than I thought. Hope that the valve springs and the injection pump get tested too. I'm a huge Daimler Benz fan but even more a fan of nearly everything that is green. So I will definitely like the Volvo- Penta green paint on the Daimler Benz engine. As always: Thanks a lot for making explaining recording editing uploading and sharing. Best regards luck and health to all involved people.

I do like this in depth rebuild. Great way to go

The filming is excellent! Loving the work! It's going to be excellent to see Minke in top form!!

That storm was a bugger, glad it was just noise!

Well done Mate good to see you and Dad sorting out the engine, that's dirt cheap Cheers Bryan

Collar things are called "collets". Great video; I enjoy boat maintenance more than sailing.

Good experience for you.

Would like to hear your dad's story, stay positive and keep going,thanks

Howdy! That is an compressive Ford Mustang setting there.

Can't wait to see it all painted up. The old boy is obviously a wealth of knowledge and an awesome mechanic.

At least you're in dePreston which still has a rewind shop, and various other engineers .. most of the rest of the country has lost those trades.

69 'Stang, WooHoo!! I saw that!! I also asked earlier. The 'Vette was an easy guess.

I really like these, the engine going back together is going to be exciting.

Thinking of that oil drain hose: The tap is at the end, not at the engine block. If the hose fails there is nothing to stop you losing all of your oil and blowing your engine, undoing all your hard work. I have seen other boaties doing an oil change, they use a suction pump to pull the old oil out. It therefore make no sense to keep the oil drain hose. I would just cap it off and reduce the potential points of failure on your engine.

The power which was in your engine must have been decreased tremendously when looking to the state of the engine, especially the crud all over. When the engine will be fully overhauled I am pretty sure you can set your hydraulic pump back to it's original settings and the engine will not die any longer when engaging the props. Wishing you success with the rebuild of the engine.

Dude that engine is your lifeline don't cheap out

Keep all of the receipts and paperwork, and make the exterior look showroom, and it will add resale value. People like bright shiny things.

You're doing the right thing

Well done getting it all back together Like others have said soak the parts in a decent degrease overnight then scrub them clean before paint and rebuild (bit late now you've already done it). Anything in the hole the engine is going in that's a pain to get to would be a great time to clean paint replace wires etc before that lump goes back in I'm sure you've got it all in hand Well done so far and I'm sure you already know your mum and dad are the best. 👍

Thanks for sharing.

Proud of you Mark, proud of dad too. That engine really needed what you two are giving it - tender loving care. Hope the rebuild goes smoothly and your season on the water a blast.

Your dad is an amazing man sharing knowledge is more valuable then just paying for the work to be done

I am really enjoying your engine rebuild. Also enjoying both of your adventures. I just found your channel a couple of months ago. I need to go back and watch your other videos when I get time.

Good luck with the engine, guys!

Looking good! Hang in there!

Top stuff Mark and Dad.

Good work! When you get back to the boat, if you haven’t already done so, empty and flush out the fuel tank! Enjoying your channel. Cheers!

Very well job done, thnx for sharing😀

That mechanical injector pump is really for the best. No computers no finicky electric injectors. That motor will run after your boat gets struck by lightning.

Keep on keeping on.

you have a pretty amazing Dad!

Don't forget head bolts. Most head bolts are torqued to stretch. They shouldn't be re-used. Great work.

It's an absolute delight watching you and your dad working so well, you have lovely parents and crazy kooky lovely wife. Brilliant Yoshi found you guys he fits in so well. BTW~~Minke is going to be great and can't wait to see you sailing.

When going through a complete rebuild like you are doing one thing you didn't mention is to what I called cooking the block. That is some thing that we had some one who was set up to do. The place that did our engines used a caustic liquid which he immerse the block in and let it set for awhile. This cleaned all the passages of grunk and grime.

What I though, you should be really really really grateful to your Dad for his help, most boat owners can only dream of having access to a workshop like that. Much respect to Steve, he's a legend 👍🏼

Great work, it’s good to get it done right.

Hi Mark, it's so nice seeing Father & Son working together, I'm reminded of me of my Dad. As for rebuilding yer engine, you're in the right part of the world to GET THINGS DONE ❗❗❗. I wouldn't feel embarrassed about mentioning how much things cost, it does help people who are doing similar projects, and shows you're Patreons where their moneys being spent. You mentioned Nadiyana, she done you proud with the video she put up. you must miss each other so much, not to mention Yoshi. So keep up the good work, buy yer Dad a beer & yer Mum some flowers, coz it wont be that long 'til yer back on board. Kind Regards, Barnacle Bern SY Cadbri SW Wales.

Well done to you and your Dad, the strip down of the engine was pretty revealing; as said a few more items need adding to your costing list polish up that sump pump too!. You haven't mentioned it but wahat about the hydraulic drives are they also being refurbished, I seem to remember loss of pressure that wasn't fully sorted befor the engine ones occurred, this might only need new seals/piping/connections to fix; water pump bearing also ought to be looked at. Nadiana will be pleased to see you and the engine and probably Dad back, at least she had Yoshi for some company! Good Luck!!

Larger pistons are the way to go. Start off fresh with a few more CCs. I would consider new valve springs as well / You don't want an old tired spring failing and putting a valve through one of those new pistons.

Most important bit of kit for the project? A Dad! 😃😃

Thanks!

Your dad needs to get an ultrasonic cleaning bath for his workshop which obviously you could use, then cleaning the parts would be 10 times better and much less effort. Do yourself a favour and get some latex/nitril? Gloves, they will save your hands long term. Good to see you taking the rebuild seriously as you should have the benefit of hassle free sailing. Good luck!

Might as well replace those freeze plugs too. When coolant goes bad it means the anti-corrosion agents are shot. ANY discoloration of coolant from what it came out of the bottle looking like denotes suspended corrosion from what got eaten away. Ethylene Glycol is extremely corrosive despite being an ideal coolant. This is why the corrosion inhibitors are so critical EG will eat ANYTHING through the temperature cycles once the corrosion inhibitors are weakened. The freeze plugs are the 1st to start losing mass to bad anti-freeze. They aren't really freeze plugs though because by the time they blow out, the block is frozen, cracked toast. Those holes were actually used by the production machines to position it for various operations down the line. I remember cleaning my first few rebuilds like that. Then I realized the positives of just hot tanking the whole 9 yards. I rather had in mind the bores would be alright as the areas you pointed out were not where the rings came in contact with. I figured the valves could be cleaned and machined as well. Those exhaust valves are probably loaded with sodium chambers. The sodium slaps up and down transferring heat to the guides. That is why the exhaust valves were so much more than the intakes in cost. Hopefully you will not need valve guides but a word of wisdom: If the guides are needing knurled to close in the valve to guide clearance you should just go ahead and have those guides replaced. The knurling works but for only so long all too many times. Knurling also lowers the surface area needed for proper heat transfer from the exhaust valves to the guide and into head. If replacement of the guides is needed I would recommend silicone bronze guides if they are available. You might want to ask the shop if they could remove the ridges from the very tops of the cylinders before honing. Top cylinder ridges will throw flat honing stones out of bore alignment. They will also bite into the balls of the ball hones popular with many. This is of course assuming there are top cylinder ridges. I can't see any reason why there would not be. If those head inserts are stellite they will most likely be removed if there is any chance they will come in contact with the fly cutter on the mill if the head does in fact end up needing to be trued.

Rebuilding your own is great fun!

if ya boring it, stroke-it!, pull some water skiers behind winki! Love your Guys channel

Good to see you rebuilding this is the right thing to do, glad the bores can be saved. Really hope the hydraulic drives are up to the challenge of a working engine! But now you will be able to evaluate them properly ! You did not mention valve guide replacement but the head fixer should be able to evaluate them when he gets the valves. FYI I think parts prices sound cheap! Don’t wimp out on good new parts especially rubber bits Cheers Warren
