@@SwapBlogRU dude I would've never watched these without your voiceovers, I'm far too dumb to learn another language but I love the content. keep up the amazing work, you literally bring my daily bad ideas to me in watchable form haha
My father was an apprentice mechanic at the end of WW2 and he had some interesting stories about the techniques he learnt for repairing engines. Evidently he used to make piston rings using cast iron sewer pipes and he used to stretch pistons by bead blasting them on the inside. For the main and big end bearings he would cast them in place by pouring molten white metal into the caps and after roughly machining them to size then use a scraper to get the correct finished size.
@@Iaintwoke I think cast iron would be to fragile for the rings. Pistonrings need to be flexible, they expand in the compression/work stroke due to the pressure in the in the cylinder.
Idea: Find an engine that has been sitting out in the weather forever (like only a block with a rusty crank in it) and put it together and see if it will start, no cleaning or anything, only free it up so it can spin.
This method definitely works! I have done it several times with a 100% success rate. Just use your hands, a flat sheet of glass and 120 grit sand paper ( it turns out that the slightly rough surface actually helps the head gasket seal better ). Use a sharpie to paint the entire surface ( that so that you know what has been scrubbed away ). When you slide the head back and forth do NOT hold it on the top. Hold it as close to the very bottom as you can. This will MOSTLY prevent uneven surfacing. Done correctly the set up takes about 30 minutes and the resurfacing takes about an hour.
@@AnalogDude_ my first one was on my totally souped up Kawasaki ar 50 and it made a huge difference to the power. It used to go 55mph on the flat really quickly.👍👊
This was great. The windshield washer motor was just pure ingenuity. The piston rings probably didn't seal, because they machined them wrong. At 11:40 you can see the ring has a visible gap against the cylinder wall (not the end gap). This is caused because when the oversize ring was compressed during installation, it didn't retain a circular shape and bent unevenly. They should have machined the rings first to cylinder diameter, then cut the gap(with a thin dremel cutting disc) and then expand them. I think this would ensure that the ring is fully the round shape of the cylinder when installed. But also might be that mild steel will not work, because it does not have enough "springiness".

I have seen this done in the Czech republic using two twenty four volt windscreen wiper motor from a TATA truck one each end with storage heater blocks to level it and one on top for extra weight to ensure even movement.
There only one thing I would of done differently is turned the head 180 degrees half way though coz the motor might have put more or less pressure on the head
Fixed many engines with a resurface like that including mine, i just put a thick glass sheet under and glue different sandpapers on it and move it back and forth, if you pull a string side to side and it doesn't have any gap and can see no to slight light when rests on a true surface it's alright as the gasket compresses for quite a few nm's, no need for a machine shop.
For real we used to resurface our cylinderheads on our motorcycles when I was younger using a sheet of glass and wet&dry emery paper, also finishing it using grinding paste and the same meathod.
Actually, you are quite mistaken there. When sub-thou's tolerances are required, no machining can deliver that. They will need to hand scrape those parts. Tracks on precision lathes being a prime example.
ring gap isn't that important for compression alone the reason the compression is shit is because piston rings usually have spring properties which these homemade pistonrings do not have
Cheaping out on rings is a bad idea. They cost peanuts for that engine, much cheaper than machining them. Sand paper deal is an old old school trick and it's proven to work, you just need to check the gap with a straight edge
Bear in mind that in Siberia you have to make it through brutal cold weather to get to the parts store to buy those peanut-cosing rings. Why subject yourself to such torture when you have lathe and raw metal in your warm and cozy garage (54)?
Cool concept. Back in 1950, this was quite common to do. Interesting to see if one still can do so, or whether this art has been lost for ever. Actually, you don't even need the sand paper, you can use a scraper and achieve even better flatness. CNC machining ain't better, but much cheaper. I guess to fabricate a set of useful rings, though, more than one video would be needed😉 Looking forward to watching this video ! Edit : Having watched the video, I'll say you're nearly there. However, those rings are undersized, and you did not face them correctly. They need a slightly tapered facing. I guess the big issue may be the good, old problem of fitting new rings and not having the barrels done. Idea for next video ?
I like the glass and sandpaper method for achieving a nice flat surface! But you'd want to be _really_ careful trying this on a OHC engine. If the cylinder head has warped, the camshaft journals in it might be misaligned, resulting in a camshaft that won't turn after the head is removed from the block. In some cases, it's actually better *not* to resurface the head, as the head bolts can flex the aluminum head into shape when clamping it against the block, allowing the cam to spin freely again. But resurfacing the head while it's in a relaxed, bent state with a seized cam could ruin it...
When I was 16, I rebuilt the engine in my first pick up. Had it all apart, had to lap the valves, the head was OK, bearings, rings, seals...yada, pretty well a complete overhaul. I grew up really poor, not much help many times, before googling something was an option. Actually going to the hardware store and asking was the way to get a fix-it guide. Some of the stuff you guys do on this channel for fun really remind me of things I had to do for necessity. I think if more young people tried to tinker and fab like this and found joy from making/rigging/tinkering, and less from zombie screens, we'd have a better world.
I will agree with this kind of method. Ive been done so many times and with almost every car with overheated issue without sending cylinder head to machine shop to re-skimming the surface...Im huge fans of you too from Malaysia! Well done!
I'm at the start and I will say I've done this with wet n dry sandpaper + WD40 for years works a treat just be careful. A full re-face? this should be fun 🍻
I love it, never say it can't be done, I think if had proper set of rings fitted it would run as normal 😀, I love the way you guys think outside the box, great video as always 😀.
I think I would have gotten some Cast iron for the ring to be made out of other than that it golden the compression is a touch higher than stock great job Garage 54
Yes. Cast iron is the correct material, must not be so hard it scuffs the cylinders. Would also wear down and seal faster. Guessing they didn't care that much for the purposes of the video.
God I love this channel. This is a completely valid way to flatten a head if it's not badly warped / gouged etc. If you have two heads you want to make sure they are both sanded to the same level. There will be a very small change (rise) in compression in all cylinders. The DIY piston rings were perhaps a bridge too far, need higher tolerances there, piston rings in modern cars are generally made from iron, not steel.
A faster way to true up the heads is to mark all the high areas with a permanent marker then get a wide blade chisel and a hammer and chisel off all the high spots. It takes a steady hand plus a critical eye but it will work every bit as well as sandpaper, a windshield wiper motor, and a pane of glass. What a great video, you guys are so inventive.

Do you think you could get a engine to run without intake rockers like how some old engines did with really light valve springs? Atmospheric intake valve..
I remember an article back in the 80’s about a Cuban garage that used black pipe to make piston rings for their 50’s Chevys to keep them running during the embargo’s. Super cool. .
Probably didn't need to go to the finer grit of sandpaper. As I understand it, you actually want a little "tooth" on the surface so it grips the gasket. Too smooth and it's easier to blow a gasket.
I have actually seen a shop in the Appalachian Mountains where a guy had a grinding set very much like that. He said that he had worked heads, flywheels, & pumps on anything from a Massey Ferguson to a Big Block Mopar.
So I've done the cylinder head thing..but man I was totally doing it wrong by hand..although it wasn't particularly warped more just needed some clean up..
for a good flat surface for sanding i use tempered glass because it is very flat and glue sandpapper to it. and dont just go in one direction.. figure 8 seems to work well
Fantastic method of resurfacing a warped head, always be sure to use a thicker gasket or maybe even two when reassembling, or just deal with more compression, haha. I fell of my chair with this video, so entertaining and funny.
Hi in homemade piston rings you need few instructions. First made pistons rings with diameter of cylinder +0.05mm Cut gaps or hammer rings to broke. Put little bit material between gaps to force re-compress rings to over- diameter Heat them and cool down. [Now these recompress bore is nominal] Remove material bit(little precision shaft) from gaps Compress overal diameter rings to nominal diameter of cyl into cylinder. Check gaps and finish them. This method make some force in structure and rings make press on cylinder walls.
i've done this a lot! perfect methode is making the nr8 with it while sanding, and you dont want a mirror finish, the fine scratches prevent oil and water coming through. but they must be in the opposite direction towards the front and back. not the sides
The other way is to just make the paper spin under it rather than the block on the top. Can do this with a roller and motor on a wheel turning paper. Join the paper in a loop around the motorroller :P. Its also a super lazy way to polish and flatten other stuff. Can do it in a punch with a drill on slow with a band on the trigger pressing it down. Basically a DIY belt sander with whatever you want sanding sitting on the top.
We used portholes on the ship. I spray- glued the sandpaper to the glass. I worked with many idiots that used grinding compound directly on the glass to resurface air compressor valves. They also used granite indication blocks and ruined them as well. Stupid is as stupid does. Your system is good but the clamps on glass will distort. You will need at LEAST 20mm glass so there is no deformity. That will last forever.
I used an electric belt sander tool to clean the cylinder head gasket surfaces. Just a few passes with it did wonders. No more rust and scale. It looked like a brand new casting. Try it.
If you can find some cast iron pipe, this is a great material to make piston rings from. Machine the OD the same as the ID of the bore, snap the ring to create a gap, quick file to clean the edges, hold the gap open with a flat blade screw driver, then heat it with a blow torch red hot to anneal it and let it cool slowly.
One more thing. If you had any type of catastrophic metal shavings or indentations from steel shavings bouncing around in the cylinder and head, make sure you get all of those steel shavings out of the head. I did a two stroke twin cylinder Kawasaki motor, which had the lower bearings come apart, and it put thousands of little indentions in the cylinder head. Well, after running it for about 15 minutes, the thing ran away on me like a diesel. I pulled both spark plug wires off, the thing stayed wide open. Only after putting a big red circle on the palm of my hand from the intake sucking the blood out of my palm, did the thing shut down, And the Machine Shop built me this motor. I guess they missed it as well. What happened was, the little pieces of steel embedded in the cylinder head, when they got hot, well, they started glowing Orange. Then, they acted like a spark plug, and it had an unlimited ignition for the fuel, & coils didn't matter, Killswitch didn't matter. Now, I don't know what it would do on a 4-stroke, but I guess we'll find out.
My local machine shop had a giant belt sander just for surfacing heads. Not milling them, just removing a couple tenths to get em flat. The machine was stationary, like a table, and the belt went round and round like a conveyor belt. You'd just hold the head down against the belt, and check it every few seconds.
i think there is a bit more to piston rings then just cutting them out of a pipe... noticed quite the gap between the 2 ends of the ring when put in the cylinder, a nice path to the base for the compression
Great job. I resurface my own heads by hand using a large machinist file. It is very true and I can get it down to less the 2 thousandths. I picked up the file at an auction so I can't tell you where to buy them but it is faster than sand paper.
On suzuki g16b engine service manual, manufacturer said if the head is deform yo should use a flat surface and sand paper n 400 i think. So is a very good way of get a flat surface, and good machine you did with the wipe motor!!
Nnnnaaaah, as far as elegant solutions go for doing it, i did it with a flat screwdriver, and a piece of sandpaper on a sanding pad 👌😃 it came out pretty good actually, no problems or leaks or whatever else, it worked like a charm. The engine was an old 16v ecotec, with another head from a junkyard, and it was good for years to come, even in the winter with high-rev snow drifting 👌😃
I planed and level this set of Harley-Davidson jugs by scraping them on the concrete floor. The guy looked at me like I was absolutely nuts. He was so worried about it, he took it to the machine shop and had it mic'd. The guy told him, whatever this guy is doing let him do it, cuz this thing is pin straight. The main thing is to keep it flat at the beginning and end of the stroke.
first time I heard about the glass and sandpaper method, I was sobbing over a blown gasket and warped head on a fiat panda at the bar.I told the guy "that just sounds stupid. Maybe it wouldve worked on a 1930's engine.." to which he cuts me off "Well, you arent gonna pay a machine shop. And its only stupid if it doesn't work" I pulled an all nighter, half drunk, did this crap, and lo and behold, it worked. I have put 100k km of abuse on that engine and still has no leaks, no emulsion, and rather good compression. Not everything that is homemade necessarily leads to a poor quality repair, although I'll still recomend to get this done at the machine shop
I've made custom piston rings for chainsaws out of fine grain cast iron. The cast iron I used to prevent galling in the cylinder walls like if I used steel. I haven't yet tried a hardened steel. The cylinders are either chrome or Nicasil plated cast aluminum, so that would be harder than a plain cast automotive block. With that said, the hardened steel may work, but I hate to ruin a vintage cylinder jug. Lol
If you just cut the gap the rings won't be round when they're compressed into the bore. A good 'garage' way is to make them close to the bore size (maybe 0.03-0.06 mm oversize), snap them to form the opening with no gap, then 'spring' them open on a mandrel and carefully (and evenly) heat the ring till it's faintly glowing red with a propane torch. This stress relieves the iron so they stay in the open state. Once compressed the ring will be much closer to round (though still not perfect). The ring can then be polished with sandpaper on glass and then gapped in the usual fashion.
Try making a large belt sander using a treadmill setup. You have the wide sandpaper and this sandpaper method has been used in a workshop in Australia. My brother was setting up a treadmill belt sander until he got sick. He could rebiuld and machine anything..
Random video idea: We all know that steam power came before internal combustion. We too know that internal combustion is more efficient than stream power. We also know that dumplings can be cooked with steam. What if we cooked dumplings with internal combustion? Drop a few into a specially extended cylinder head and see what's going on! :)
Those piston rings if you want that to work you need to hone the cylinder walls and put a slight cross hatch in the mating surfaces of the rings to the cylinder wall. Generally a new piston ring will have cross hatch on it as well to blend both materials of the bore and ring to a sealing surface as the new rings seat themselves to a new bore.
Had they rubbed some sandpaper on the cylinder walls for a quick homemade hone those rings would have worked much better. Funny seeing them talk about twisted heads when the one on my Volga was like twice as twisted as theirs.

Depends on the gasket. As I understand it with a modern multilayer steel gasket a smooth finish is needed.
I have actually seen a shop in the Appalachian Mountains where a guy had a grinding set very much like that. He said that he had worked heads, flywheels, & pumps on anything from a Massey Ferguson to a Big Block Mopar.
So I've done the cylinder head thing..but man I was totally doing it wrong by hand..although it wasn't particularly warped more just needed some clean up..
for a good flat surface for sanding i use tempered glass because it is very flat and glue sandpapper to it. and dont just go in one direction.. figure 8 seems to work well
The rubber strap was smart 💡
I can’t believe you made piston rings 😆
Damn, these guys think outside the 📦
Fantastic method of resurfacing a warped head, always be sure to use a thicker gasket or maybe even two when reassembling, or just deal with more compression, haha.
I fell of my chair with this video, so entertaining and funny.
Hi in homemade piston rings you need few instructions.
First made pistons rings with diameter of cylinder +0.05mm
Cut gaps or hammer rings to broke.
Put little bit material between gaps to force re-compress rings to over- diameter
Heat them and cool down.
[Now these recompress bore is nominal]
Remove material bit(little precision shaft) from gaps
Compress overal diameter rings to nominal diameter of cyl into cylinder.
Check gaps and finish them.
This method make some force in structure and rings make press on cylinder walls.
Very interesting video! Piston rings are made from very hard cast iron with high carbon content
with that higher compression, the engine's ready for a diesel conversion :>
i've done this a lot! perfect methode is making the nr8 with it while sanding, and you dont want a mirror finish, the fine scratches prevent oil and water coming through. but they must be in the opposite direction towards the front and back. not the sides
The other way is to just make the paper spin under it rather than the block on the top. Can do this with a roller and motor on a wheel turning paper. Join the paper in a loop around the motorroller :P. Its also a super lazy way to polish and flatten other stuff. Can do it in a punch with a drill on slow with a band on the trigger pressing it down. Basically a DIY belt sander with whatever you want sanding sitting on the top.
"the engine doesnt spin fast enough to fire up"
google: replace starter, check compression, take to professional
bing: WELD ANOTHER CAR TO IT
We used portholes on the ship. I spray- glued the sandpaper to the glass. I worked with many idiots that used grinding compound directly on the glass to resurface air compressor valves. They also used granite indication blocks and ruined them as well. Stupid is as stupid does. Your system is good but the clamps on glass will distort. You will need at LEAST 20mm glass so there is no deformity. That will last forever.
Great to see you guys love to muck around trying out different things for cars
Imagine doing work experience at Garage54 and explaining to your tutor “don’t worry, I’ve got this…” 🤣🤣🙏
There went your eyebrows ha ha. Awsome job fellas.
I recall they do teach this at mechanic training schools where I'm at.
i would like to see more do it yourself hacks for emergency situations and off grid solutions to auto repair more please !
Particularly 4x4 stuff for me.
I used an electric belt sander tool to clean the cylinder head gasket surfaces. Just a few passes with it did wonders. No more rust and scale. It looked like a brand new casting. Try it.
If you can find some cast iron pipe, this is a great material to make piston rings from. Machine the OD the same as the ID of the bore, snap the ring to create a gap, quick file to clean the edges, hold the gap open with a flat blade screw driver, then heat it with a blow torch red hot to anneal it and let it cool slowly.
One more thing. If you had any type of catastrophic metal shavings or indentations from steel shavings bouncing around in the cylinder and head, make sure you get all of those steel shavings out of the head. I did a two stroke twin cylinder Kawasaki motor, which had the lower bearings come apart, and it put thousands of little indentions in the cylinder head. Well, after running it for about 15 minutes, the thing ran away on me like a diesel. I pulled both spark plug wires off, the thing stayed wide open. Only after putting a big red circle on the palm of my hand from the intake sucking the blood out of my palm, did the thing shut down, And the Machine Shop built me this motor. I guess they missed it as well. What happened was, the little pieces of steel embedded in the cylinder head, when they got hot, well, they started glowing Orange. Then, they acted like a spark plug, and it had an unlimited ignition for the fuel, & coils didn't matter, Killswitch didn't matter. Now, I don't know what it would do on a 4-stroke, but I guess we'll find out.
I used a whetstone dressing stone on a Miata head. Smooth as glass and worked great. Light pressure.
You all did a great job on this. Thanks.
My local machine shop had a giant belt sander just for surfacing heads. Not milling them, just removing a couple tenths to get em flat. The machine was stationary, like a table, and the belt went round and round like a conveyor belt. You'd just hold the head down against the belt, and check it every few seconds.
yooo this channel is the best out there on youtube handdown hahaha love it!
Vlad is cool. He needs to come to America for a meet and greet.
Y.E.S!! i sanded my head too!! it works well.
Thank-you 54G
I did this 15 years ago and got it to 0.001 150k miles 10 to 1 compression. Still running good. I use 6 mm glass.
i think there is a bit more to piston rings then just cutting them out of a pipe... noticed quite the gap between the 2 ends of the ring when put in the cylinder, a nice path to the base for the compression
Great job. I resurface my own heads by hand using a large machinist file. It is very true and I can get it down to less the 2 thousandths. I picked up the file at an auction so I can't tell you where to buy them but it is faster than sand paper.
Would be interesting to see if with proper rings that head finish would have given good compression.
On suzuki g16b engine service manual, manufacturer said if the head is deform yo should use a flat surface and sand paper n 400 i think. So is a very good way of get a flat surface, and good machine you did with the wipe motor!!
There are a couple machine shops, old ones, around here and that's how they resurface heads. Basically a big belt sander.
Ive done my cylinder heads myself using this method, (but with out the windscreen motor thats neat !!) for many years
Ive done this on vg30e. And also a 2azfe aswell as the block and im 3000 miles and counting. You do what you have to do to get by
Me and my brother used the same method for a rm 125. Tons of compression amd still a good seal.
Nnnnaaaah, as far as elegant solutions go for doing it, i did it with a flat screwdriver, and a piece of sandpaper on a sanding pad 👌😃 it came out pretty good actually, no problems or leaks or whatever else, it worked like a charm. The engine was an old 16v ecotec, with another head from a junkyard, and it was good for years to come, even in the winter with high-rev snow drifting 👌😃
I planed and level this set of Harley-Davidson jugs by scraping them on the concrete floor. The guy looked at me like I was absolutely nuts. He was so worried about it, he took it to the machine shop and had it mic'd. The guy told him, whatever this guy is doing let him do it, cuz this thing is pin straight. The main thing is to keep it flat at the beginning and end of the stroke.
Copper gasket spray will fix it. If not try duct tape. Red Green told me so.
first time I heard about the glass and sandpaper method, I was sobbing over a blown gasket and warped head on a fiat panda at the bar.I told the guy "that just sounds stupid. Maybe it wouldve worked on a 1930's engine.." to which he cuts me off "Well, you arent gonna pay a machine shop. And its only stupid if it doesn't work"
I pulled an all nighter, half drunk, did this crap, and lo and behold, it worked. I have put 100k km of abuse on that engine and still has no leaks, no emulsion, and rather good compression.
Not everything that is homemade necessarily leads to a poor quality repair, although I'll still recomend to get this done at the machine shop
I think the wiper rotation should be horizontal rather than vertical in order to prevent potentially high and low pressure points on the head.
This is apocalypse grade engineering : Crazy Russians. I love it!
Russians will be the only guys driving, post apocalypse. Will be an army of Ladas however...
Yes... This is really old fashioned, roots. We used to did this a lot with VW air cooled.
I have an idea, probably a rather difficult one but I could see it working, glass pistons
I've made custom piston rings for chainsaws out of fine grain cast iron. The cast iron I used to prevent galling in the cylinder walls like if I used steel. I haven't yet tried a hardened steel. The cylinders are either chrome or Nicasil plated cast aluminum, so that would be harder than a plain cast automotive block. With that said, the hardened steel may work, but I hate to ruin a vintage cylinder jug. Lol
That was an epic video. I love it. Thanks for sharing it with us. I really enjoyed it.
Thank you for the wide video. its nice not having huge black bars on the sides of the screen.
😎 I had as much fun watching your show as I used to watching the old Top Gear thank you
You guys are crazy! Love the content, just shows what can be done to get cars running at a push. It’s like post-apocalypse mechanic-ing.
Yes cast iron to make your rings. Make them a bit larger than the cylinder. Grind the gap so they fit and you have your self a ring that will be 107%
If you just cut the gap the rings won't be round when they're compressed into the bore. A good 'garage' way is to make them close to the bore size (maybe 0.03-0.06 mm oversize), snap them to form the opening with no gap, then 'spring' them open on a mandrel and carefully (and evenly) heat the ring till it's faintly glowing red with a propane torch. This stress relieves the iron so they stay in the open state. Once compressed the ring will be much closer to round (though still not perfect). The ring can then be polished with sandpaper on glass and then gapped in the usual fashion.
Try making a large belt sander using a treadmill setup. You have the wide sandpaper and this sandpaper method has been used in a workshop in Australia. My brother was setting up a treadmill belt sander until he got sick. He could rebiuld and machine anything..
Random video idea: We all know that steam power came before internal combustion. We too know that internal combustion is more efficient than stream power. We also know that dumplings can be cooked with steam. What if we cooked dumplings with internal combustion? Drop a few into a specially extended cylinder head and see what's going on! :)
Those piston rings if you want that to work you need to hone the cylinder walls and put a slight cross hatch in the mating surfaces of the rings to the cylinder wall. Generally a new piston ring will have cross hatch on it as well to blend both materials of the bore and ring to a sealing surface as the new rings seat themselves to a new bore.
Had they rubbed some sandpaper on the cylinder walls for a quick homemade hone those rings would have worked much better.
Funny seeing them talk about twisted heads when the one on my Volga was like twice as twisted as theirs.
A proper cylinder hone costs peanuts anyway.
This is good content. More zero budget Russian tech type stuff, please!
Try welding the cyl head to the block
You should do a full engine rebuild tutorial! There aren't many tutorials for old engines
DIY piston rings from pipe. Freaking awesome!
Making piston rings...now that's ambitious!!!
check your Eyebrows sir!!! 😆
