I love the mad scientist lubrication system- very cool :)

There is an ebay store specializing in antique used parts that has several items from a Terraplane engine that he dismantled. Fairly reasonable prices as well. This video series is of special interest for me as I will be rebuilding one of these in the near future.

I'm one of your fresh subscribers. I went back and binge watched your older videos. I love the small channels like yours. No BS. Only true enthusiast content. I hope you keep it this way.

Hudson used a unique low pressure splash oiling system. Pump only put out 5 or 6 PSI. It fed oil to troughs under each connecting rod. As the crankshaft rotated, the scoops on the rods would scoop up oil into the rod bearings and throw oil around inside the crankcase. Oil would run down the side of the engine where it was channeled into the main bearings, cams etc. The cylinders are very close together with no coolant passages in between. This means uneven cooling which is why the rings are pinned in place. You can see that you can't bore the cylinders very far because of the thin metal between the cylinders. Hudson made an extremely simple, light, and short six cylinder engine. It looks like it shouldn't work but in normal use they worked very well. The English Railton company made some fine performing cars on thirties Hudson chassis. Another thing that worked far better than anyone would think, was the cork lined oil bath clutch. An important point for Australia is that they were free of asbestos and can be relined with wine bottle corks or bottle corks from the hardware store.

Great work dude! "Couldnt be happier" how good👍🏿

Honestly, I like the ideas of upgrading to custom pistons with a modern ring pack. It's not like you will see it in use, and it's bound to work better and more reliably! Keeping things original is all well and good, but sometimes a sneak upgrade is a great idea.

You have interesting projects👍 I've never seen a Terraplane engine disassembled. Very interesting. Greetings from Finland on the other side of the globe.

Cool, I have never heard of the Paraplane until I saw your video.

Good on you mate this is true life , cheers , shaneo, Nelson, NZ, 👍🍺

Even if you have to sleeve that old engine, its worth saving. Its a rare piece of history, and I think its in good hands.👍

Well done Bro thoroughly enjoyed both parts very interesting and informative , sound wasn’t to loud and very clear on 2nd one just like I was in the shed with u. Keep on it Mate Jeff👍😜🏁🇦🇺

Great viewing lets hope you can get it running.🔧🔨😊👍

It's just unbelievable for the era of this engine how they backed up the oiling system. A very unique engine with a simple but unique design. Thanks for the part 2 it's very much appreciated I was just thinking about you guys the other night and here you are right on cue. I will be waiting for part 3

The algorithm is working mate. The previous video popped up today from me watcing other car and restoration related channels. You got my sub, keep it up 🤙 Quick Valiant story...one of my scariest (passenger) experiences was in my uncles Centura that had a worked 265 slant with triples. That thing was rapid... always scared the shit out of me as a young fella. 😁

very interresting engine, looking forward to restoring it, greetings from Belgium, Europe

Here's a thought...It may be easier to find valves with the right head, but a smaller stem. It would be easier to make up some custom valve guides rather than machine valves.

Hello from Seattle. Enjoy your channel. New sub Take care brother!

Some 80mm diesel pistons would work with a bore job Mate! Check Yanmar & Kubota stuff. Watching from snow bound Idaho.🙂

You get what you give. The quality of your explications and explanations is superb, as is your patience when speaking to viewers who missed some of your earlier comments. Thank you for sharing what you are doing. Cheers from NZ🇳🇿. P.S. Good KZfaq videos are worth the wait.

14:41 In this day and age you could send 1 good piston to an engine engineering shop and have some copies made to the size of your choice after boring the liners. They can just use a 6 axis inc machine (i think 6) and a block of billet aluminium to make as many as you need.

I've spent a night, I think back in 2008, Coober Pedy. What a strange place it is.

You should be able to find a sleeve and then get the standard pistons

Another interesting video on the Teraplane engine. I hope you can get it going and I understand it’s going to take time, especially if parts need to be made. In your other video about the first drive of the Valiant I observed some distinctive landmarks in the background, just south of PA which I have seen on trips through the area so I was able to establish your location before you said you were in SA. It’s great to see another Aussie video on KZfaq. Keep up the good work. Thanks.

This pom is very much looking forward to watching your progress however long it takes.

I’ll be very interested watching the progress on the terraplane engine I have 3 terraplanes with engines, 2 of them I’m going to do up eventually

Love what you bring to the table mate...Cheers.

Some of those valves were devastating, lol. That block casting is pretty elaborate.

The piece you said was an oil pump is probably more likely what is known as a ventilator. Bore the block and sleeve it to bring cylinders back

Hudson’s used pinned rings on there older engines because the cylinders were Siamesed and didn’t have uniform cooling. The out of round condition could cause excess oil usage if the rings moved. 12:24

G'day mate, in regard to bores we used a small local machinist who made steel sleeves and after overhead boring old cylinders just past the pitting but also enough for new cylinders to have some meat on them if you know what I mean, pressed the new sleeves into the block so you can use STD pistons again. Very quick and easy although you need a machinist who knows what they are doing for interference fit and who won't dick you around. Did you notice the old rings you showed they were inline and not offset !? Very strange. As a Diesel Fitter myself and doing some old gear restoration (Tractors and Dozers) for fellas also use to hand scrape white metal bearings just like you showed in latest YT.. Car clubs for Hudson there may be a bloke with a set of pistons in his shed. Getting in touch with those type of people may help you heaps from my own experience. . All the best mate

Good vid ! Knowing how the temperature can be in central SA can i suggest you give a temperature report just so people know how b!oudy hot it gets in your shed ! Try and find someone with an ultrasonic cleaner to free up the oil pump.

Sleve the block to fit the new pistons. ESY Psy had an old flathead motor that had froze numerous times, Colorado winter, had Stickneys sleeve the block worked great!

Can’t wait for the next video on the terraplane engine.

If the bores can be cleaned up more with a minor overbore, then contact one of the aftermarket piston manufacturers like Venolia in Long Beach California - they can make a modern style piston.

I didn't read all the comments from the first video, but from those I've read it seems nobody mentioned 'Terraplane Blues- Robert Johnson'.. Wouldn't recommend using it for intro music though, instant copyright strike.. Love your work.

It's side valve so run the timing gear till it don't run

I'm one of the new subs because of getting a recommendation about some guys down under with a Teraplane engine 😎 Those were really special engines and cars in their day and it's cool that you folks got them too. I'm a Mopar guy too and I still have the 69 Dart I got my license in retired in the backyard. Looking forward to watching the series till it runs again.

Use the NOS standard pistons from USA, but bore the block and fit liners.

Hudson terraplane they have a few sets of valves here in the states. One set was around $60. US dollars if it helps.

May I suggest you try NZ for parts. One of mates has restored several Austin's & has sourced engine parts from there because the Kiwis are masters of keeping old cars going. Don't worry about taking long time to complete this project because it will give people an realistic understanding of how long jobs like this take

For the iffy valves there used to be a process used called "stellite" to build up the seating surface. I remember my dad using it for his rebuild of a 52 twin spinner Ford in the 60s.

If you find the Honda pistons are too short, it would be easy enough with a lathe to make an alloy block to bolt to the top, wouldn't be too worried about balance. My friend and I have a saying. "Imposabilitys just take a little longer to solve".

Captive spring is the spring/tubing combination. You could be right about dampening or harmonics with them slotted. I dunno beside pew-pews use them sometimes on long buffer springs.

Great to see the inside workings. Is it possible to weld old piston together and machine up. It's just a engine on a stand. Don't think I'd get to crazy with it. I'm sure you find some valves you could machine up. Guess block needs acid dipping. Maybe just takes up shop space. Maybe donate to a museum. There has to be a perpose to it. Must be somebody in Aussie restoring these engines and cars..join the Terraplane club. Somebody have some old parts cheap. Good luck. Thanks for the video. Have a good week.

Sleeve the bores and get the pistons from the states, the engine will be happier in the end.

Im one of the new subs! I’m curious of 2 things… 1. What the power output of the original rebuild. And 2. If you were to get more modern parts or make your own replacement, what if any power improvements would it have? (Deep clean the block [submerged chem clean], magna flux for cracks, then put performance parts in [even if parts needed custom], see improvements… and then sell as a performance rebuild 😅).

Add a piece of aluminum plate to the top of the Honda pistons to raise the compression height. You could weld it on or attach it with screws from below. Just a thought.

I watched your last post on this engine . Considering it age , laying on it's side outside , & all of the water in it , I'm not surprised at the losses . Still , it has a number really cool design features . You also have most of the pistons , & valves . The cylinders looked better than I thought they would . With running & time , the rings will erase the pitting in them . Not much of a ridge ring in the top of them either . Good looking bearings with shim stacks , means they have plenty of life left . Soak the good pistons in trans fluid , warm them up from time to time , & tap them with a soft hammer , small dead-blow , plastic . The rings will free up in time , which it sounds like you are going to have , between day jobs , & part replacements . Hopefully , your project will attract the notice of those who can help you find the resources . I have no doubt it will run again , if you have all of the parts back in , & in good order . Any pistons you use , will have to match in weight , for best results . I'd definitely be cleaning the block up , & checking for cracks , before putting in much more time & expense of restoration . I'm guessing that oil pump pushes oil to the top oil channels , where it gravity flows down to all of the cam & crank bearings , plus out the front for timing gears , dumping down to the upper crank pan galleys for the rods to pick up in the scoopers . It must have done well enough , the bearings look fine . Best of luck to you !

Well done mate.

When dad was courting mum he had a hudson terraplane, his least fond memory was the cable operated brakes.

So cool to see you reviving this old girl. Believe it or not, this basic engine began in 1924 at about 130 cu. in. in the Essex, growing in displacement thru the late 1920's and early 1930's when the Terraplane series was introduced. Yours appears to be the 212 cu. in. version (the largest six in the series) The straight 8 Hudson was a stretched variant. Note how narrow the space between the bores is! Pinned rings was a standard Hudson feature throughout their history and not great. The earlier years in this engine series had roller cam / lifter setup, Depression era cost cutting did away with that. Even in 1924 , most mid class and better cars had gone to full pressure oiling, but the old Hudson splasher setup works quite well. These are neat engines and run / sound really good for what they are!

Valve 1.558 diameter x 0.372 stem x 5.436 length for 8 USD can be had. Not sure what actual specs you need. Thanks for the video!

I love the idea of getting this thing going again, but I think you will have to start looking at side valve stuff for compatible parts. The side valves normally had longer valve stems and the pistons were more like what you are after. My BSA M20 motorcycle ( 500cc side valve single ) had a bore of 3.2" as standard with a large deck height like those things and the extra oil control ring at the bottom, so you might want to start looking at motorcycle stuff too. As for the valve guides, after finding appropriate valves you could machine some bronze guides to suit the new stem diameter if it is different.

Get a Motors manual for 1950 or older. I have one, it goes back to 1935 and give all the necessary information.

A few years ago I had the privilege of helping to facilitate the restoration of Willy's Super Hurricane and an L-4 124. Thanks. I can still remember the smell. It's gotta go.

Maybe try using electrolysis to free up the oil pump? Unless there is alloy parts internally.

Fun project, tried bringing a 36 Cadillac straight eight flat head back to life a few years back and parts were nonexistent good luck to your brother

Why don’t you get those OEM pistons from the US and bore it and fit dry sleeves? Good luck. Great content BTW.

I had one of these reconditioned years ago with austin A60 pistons. Probably just as hard to get now as teraplane ones.

There are epoxies that are capable of filling in pitting on cylinder walls. Might be worth a try.

Highly engaged in your project... wondering about the nature of those lower piston rings... perhaps they were intended to created positive internal crankcase pressure on the engine oil to help circulate what appears to be a very ''passive'' oil pump set up.

All hail the algorithm. SuperfastMatt. I understood from the first video how the engine ended up in that car so any misunderstanding on that isn't on you.

If someone wanted to see an example if casting your own pistons, I think the movie 'Worlds Fastest Indian' with Anthony Hopkins showed a pretty good clip of it being done.

Looking forward to see the next step of Rebuilding the Terraplane engine, But Parts are going to be rare as Hens teeth, I Would Highly Recommend Trying to buy a another complete or Parts Terraplane engine, Thats if you can find one, it's going to make your Job much easier & Quicker too.

G'day Uncle Brent! There's another "Uncle" on KZfaq that has a cylinder "patching" video using JB Weld. I know that it's not the "right way" but I get the sense that you would like to get the Terraplane going without spending a mint. Check it out. It's entitled, "Can You Repair A Pitted And Gouged Cylinder Wall With JB Weld? Let's Find Out".

Gruesome Garage seams to know these cars.. Talk with him on some second hand parts and tech advice.. I just watched his video. Plenty info. Good luck..

is it worth sleeving the cylinder bores back to standard

It wouldn't be too difficult to convert that to pressurized oiling. Fill the main gutter with molten aluminum or powdered aluminum and epoxy snd drill and tap it.then run steel lines from the pump, the same with the cam bearings , as for the main snd rod bearings. Id at most remove some of the shim. Then bore them to size with oil clearance. And polish the rods, only removing .002" or so very minimal. Just enough to get them smooth, removing stress risers. Possibly drill the crank for rod bearing lubrication. Definitely add zddp to the oil. We dont make oil for engibes like this anymore. Maybe get some liquimoly oil or additive. And drill tiny holes to the cam lobes. And set up the lifter area. To be an oil bath. Keeping it nearly full of oil. It could have miltiple oilers to the cam. With pressure feeding the cam bearings. Look into getting a custom tool steel cam ground. Machine adapters with brass bushings to allow the use of chevy or 3.8 buick 3800 roller lifters. Maybe more lift than the buick would have had. Probably modify the roller lifters to have adjusters. Be solid no longer hydraulic this will likely allow slightly shorter valves. Allowing replacement dodge valves to be modified and used. It could be a s interesting project..

Microphone is good.....

We used early Holden rings in the straight eight.

Egge Machine in California custom makes pistons for antique engines.

The bloke who invented that motor suffered from severe headaches and lack of sleep . 🙀🤦🏼🤔.

It has a Rube Goldberg oiling system.

Is there enough material between the bores to allow a re sleeve? How about spray metal linings?

Hi from the uk Those bores are really not good if over size pistons are not an option how about sleeving the block back to std or to a size that will accommodate an off the shelf piston

That block already has sleeves in it. A good machinist should be able to replace all of them. Then you can use the standard pistons. Do the job right!

Such an interesting project!!! Do you plan on installing hardened valve seats? It would save having to use leaded fuel or lead substitute....

Engine block looks solid. That Bakelite gear? Find a new replacement, not NOS, but actually new. Bakelite deteriorates with age, and as far as I know actual Bakelite? Stopped being made in the early 70s because making it is a toxic mess.

OLÁ. Fazem muitos anos que eu não via um "sucatão" com sistema de lubrificação de bielas por PESCADOR. Pepino prefiro em conserva. ABRAÇOS... Roberto Udo Krapf

New sub here from last video just a tip don’t keep the mic so close to your mouth it’s over modulating. Enjoying your video so far!

Far more interesting than watching some youtube idiot influencer taking apart a 2JZ! Thanks👍

Try Bedford, about 1970 Ted from Qld

That block needs sleeving, those big bore divots can't be ignored. Then you can use standard size pistons.

👍🏻💯🇦🇺⛽️

Is this the same engine as the Diamond sidevalve engines ? How many cubic inches ?

So are You going to put this in the mismatched car that it was in at the junkyard?

I had 2 sleeves fitted to two of my hemi blocks, it’s not that expensive, only mentioned it because you said you can get stock pistons. This is an interesting project.

Ivan shed racing mit have info on your terraplane

Piston mould..

Those bores are fairly bad, the block itself NEEDS A LONG LONG SOAK in HOT bath to dissolve all the crud and get it out of there, ideally the block needs new bores but it would cost!! Do Not give up patience and perseverance, it will take Time and money!!!!

Bad Chad just pulled one of these engines out that he isn't going to use. Check that out, maybe he will sell the engine?

Engine looks like it has dry sleeves

You probably know that a hot tank cleaning will destroy your babbitt.

Those bakelite toothed wheels are reportedly prone to failure. I can understand you wanting to keep everything authentic and original but you already know that's not going to work. If that bakelite wheel fails or breaks then all of your work will have been wasted. I personally wouldn't risk it.
