Kfplus, I’ve been making loads of engines now and I’ve found that a 2 cylinder 4x4 is the fastest for me. The single cylinders I have built are way slower with no throttle response. How do you make your singles so quick?
I made the exact same one cylinder as he did and it runs the exact same. Try experimenting with his mechanism and make sure to lubricate the parts for best results
I didn’t have all of the parts for this engine so I had to improvise. After hours of mind numbing adjustments I was finally able to get it running at it was so satisfying. Thanks for the video and for people looking to build this, don’t give up! Even if you don’t have all the parts, get creative and use the different parts to get the job done. Only thing you absolutely need the exact same pieces for is all the crankshaft parts. The small 1 and 1/2 pieces are essential for the engine to run and they have to be at a 90 degree angle to the 2 hole cranks on the piston side.
Thats a signature "feature" of LVEs.. they are loud and vibrate a lot. I can shake my entire house with just one fast engine, its crazy. Maybe I will design a counterweight for the crankshaft!
@@3rd_ACC did you have any trouble with it being stiff? i cant tell if its my flywheel being small or the crank is rubbing against the conrods. with the vacuum attatched nothing happens despite how fast i spin it
I built it just now and it sounds amazing and is really fast. I didn't want to glue the piston head and I accidentally started my vacuum on full power and it sucked the head right of 🤣 I needed to substitute some critical parts since I didn't have them available but it still runs incredibly smooth. Really nice work 👍
This works so well even though I improvised so much even if you don't have the parts it still works cant wait to see new videos and a tutorial with a shifter.
im not sure if you’ll see this, but does this require a powerful vacuum? i followed your guide and had a look at other tutorials, and the engine is properly assembled but wont run.. i regularly put water in there to lubricate it when testing and it does the job. any tips?
What I had to do was adjust the crank timing - I had accidentally made it 180º instead of 90º. Then I put olive oil on the contact areas and added a second wheel to the output shaft and it runs great.
Try changing the wheel I had the same problem and messed around with it for hours and then changed the wheel, started working almost immediately after a few manual start up spins to the wheel, I didn't think the wheel made much of a difference but I was completely wrong
Trying to make it but don't have the right pieces could you tell me what the small orange thing at the too left if the parts part is and same with the wheel
i made a similar engine but when i get closer to 6000 the piston is moving up and down so fast that it rips it off the crankshaft and it shoots through the top of the engine
You can very easily replace that piece for a 2 stud long one, you may have to adjust the length of the valve connecting rod but it would definitely work. My first LVE on youtube utilized that crank setup and it worked just fine.
pretty good tutorial! i would love to see something like this but a tutorial of the rotary valve lve. it seemed really smooth and i want to know how to make it
I had all parts at home and it works perfectly thank you ❤. It just took me 5 hours to find them all in all my Lego chests. 😂 Now mine is even pretty much all red 🔴
Just made one of my own, and I gotta say, I'm impressed. I don't have a wheel that big but I got one that works, I also tweaked the throttle a little and I noticed slight improvement. Cheers! Side note: how do you keep your vacuum on the engine? Mine is constantly slipping off, also whats the song playing in the background towards the end?
@@wezeledelman761 I did, but it still managed to slip off. It's not a super big issue as I can just hold it there, but enough to where it's a little annoying. The tire works great as a seal tho
Hey this might sound like a big favor but can someone help me track down these pieces or at least point me in the right direction? Really want to make one of my own after seeing this video and all these comments.
Hey I’ve made the whole engine but I need help with putting the vacuum on and getting it to spin with the vacuum and to get to consistently spin can you please post a video on your tick-tock on your TH-cam telling us how to get it to start spinning
Can you please make a video explaining not how to build a lego vacuum engine, but the parts and how it works. I really want to build a lego engine but I just don’t think I’m understanding everything. I know this is a tutorial but I would rather build my own design
You have a valid point my friend. I will be doing an in-depth video about how an LVE works along with how to calculate its displacement in cc. Stay tuned!
Can you make one using technical Legos? They are considerably more stable and offer much more functions than conventional ones which I think would be interesting to see. Anyways, your engine worked really well thx 😁
THANK YOU VERY MUCH i builded it and it sounds like beast and yeah i didnt glue my parts and i did max throttle and the engine just breaked but its easy to fix
I finally made it. A solid connection DOHV Lego vacuum engine using a 4x4 piston. The base is only studs in length, and six in width. I believe this is going to be the first of this kind on TH-cam. (I inspired it from my other design for the chain driven one) I'll post it sometime soon :D :D. After some research I believe that it might possibly be the fastest of the pushrods ( With consideration that solid connections are like a family of the cam actuated ones).
@@KFPlusLegoMastery yes but that design revolves around cams. My design does not need springs. Thank you. Ill post it soon. I feel like I don't do a good job at explaining it lol
Amazing video man thanks so much I got it to work after you said the Half crank had to be 90 degrees ahead of the other piece, very important and it was so satisfying after I fixed it
I have an issue when building, the part made at 12:03 doesn't give enough clearance for the valve to spin fully, the 6x1 technic piece hits the top of it any help is appreciated.
That was the same for me, but that's because I didn't have the proper pieces. What I did though, instead of that 2x6 plate, was I took 2 2x2s and a 1x2 and placed it, so it looked like this kinda [ ]__[ ]
Hi everyone, I just finished building this awesome engine! But I am struggling to get it to start. Does the vacuum have to seal really well against the intake? Or any other tips to help get it started!! Thanks 🙏
@@KFPlusLegoMastery what would happen? Sorry I’m not good with engines…. Anyways one question is that is there a substitute for the two grey pieces that have two crosses in them. They are thin and rounded and used for the piston to keep it in place
@@acast7 To answer your question, yes. You can substitute those two pieces with 4 of the half-stud axle bushings (they’re usually yellow or light grey color). Works exactly the same- Good question!
Kfplus, I know it’s been a year since you made this tut but is there a different part I can use instead of the beige thing you called the crank? I don’t have one and i really need to make my engine work. Hope you reply 😊
Little tip to make your vaccum engine significantly faster instead of using the 1x1 hole on both sides for the intake. Just use it on one side, and then you will get a lot more airflow into your cylinder, which will give you higher performance. I hope this helps :)
idk why and who and what and when but i somehow got the idea to search for lego motor and found this part of the lego community, want to build one very soon if i have the pieces, great video!
I built it with all the pieces but mine doesn't start as easily as yours, it looks like the crankshaft is stuck to the vacuum and doesn't want to let the piston go up, do anyone has any idea on how to improve it ? Also nice video ty for your model 💙
How long is the valve arm because when I make mine the valve gets caught on the plate you put under the cylinder head and I’m wondering if maybe my valve is too long
@@KFPlusLegoMastery btw i dont have many 1x1 pieces with a hole in them can i build the engine with 3 or 4 of these and if yes on what part should i use them

@@KFPlusLegoMastery ok thx
Can I get the parts list plss I can't see from the pic well
Kfplus, I’ve been making loads of engines now and I’ve found that a 2 cylinder 4x4 is the fastest for me. The single cylinders I have built are way slower with no throttle response. How do you make your singles so quick?
reduce the piston crank to 2x1 and valve crank to 1.5 and a smaller flywheel i once made one and it ran on a car vacuum
@@redstonegod296 2 cylinders can run without a flywheel and piston stroke is 3stud valve is 1.5 stud i think
@@niteh4wkk926 make the crank 1.5 instead of 3’s. Less torque but also less piston speed meaning more speed
dam what language ya speakin tf
I made the exact same one cylinder as he did and it runs the exact same. Try experimenting with his mechanism and make sure to lubricate the parts for best results

do you think you could make a video for what you did? i dont have the orange piece for piston or the skinny 6 tec piece one for the valve & crank
Nice i also do the same thing but im hgoing to improve by making small ones
Where did you find the 1 and 1/2 pieces?? I can't find them anywhere
Can you please tell me how you built yours because I don’t have all the parts either
@nerd5809yeah pretty much, or but the technic sets or whatever they’re called
Made my first one tonight! Had to improvise a decent amount due to the lack of some pieces but eventually she roared to life! Awesome video, thanks.
Same
Hey man! Since u lard had a startup can u tell if you turned to vacuum to suck or. to blow?
@@SubfordimondsIt is supposed to suck
@@Subfordimondsboth work but you need to spin it counter clock wise if you want it to blow and suck is louder then blow
dude. HOLY CRAP. IT VIBRATES SO HARD WHILE RUNNING. But it runs so smoothly and works so well

You have to use the kragle.
Best comment by far

Glad to see you had success :) I have an idea for an indestructible piston that will require no glue to stay together, so stick around!
@@KFPlusLegoMasteryI just build this, aplied the vacuum onto it, turned it on,put the engine on FULL THROTTLE. and guess what. NOTHING HAPPENED
@@3rd_ACCtry again
@@spritewitha2I have the same proplem,it doesnt work.
I just started making engines last night after seeing this channel it’s been great and was wondering how you measure the rpm of the engine?
Look up tachometer on amazon
I use a hand held laser tachometer, you can find them on Amazon for $20-$30
How do you actually connect the vacuum to the back of the engine? This is the first video I’ve watched about these they’re sick
I'm also wondering this!
Looks like he puts a Lego rubber tire on the tip of the vacuum, and then puts it up to the "window" for the intake. The rubber tire helps it seal
You put a Lego tyre on the tip of the vacuum (obviously take the thing on the top off) and that helps it suction
OMG this is so cool. It took really long to find the bricks but it works! thanks for tutorial
Where didu get all the parts for the whole build
This works so well even though I improvised so much even if you don't have the parts it still works cant wait to see new videos and a tutorial with a shifter.
What are the substitutes for the two yellow crank things?
What vacuum do I use and how do I connect it? Also, great tutorial.
making my first engine now thanks for inspiring me
Thanks for parts list my guy
you didnt explain nothing i needed to watch this a trillion times
Or your just horrible at following simple steps😂 it was easy to watch
This is gonna be epic
Hey could you please give me some pointers. I have no clue what I did wrong but my motor won't work at all
Is there any substitute for the orange technic piece in the engine?
Same idk what to put for it
Hey does the vacuum blow the air out or suck the air in?
It sucks in air, but if you make it blow, the wheel will turn the other way 👍
@ okay thanks
Just built mine. Sounds amazing, and pretty reliable if you glue the piston and valve.
Mine didnt even run altought nothing was wrong
@@veikko3426 same for me I spend 3 hours building it and it doesn’t work
@@veikko3426 ok it works now I used a different wheel
What glue do you use?
@@Drewskii55 I used Tamiya Cement. Super glue would probably work just as well.
I came here from the first video of this playlist, and you've grown so much! In views and in age, I hope you make it in life man
Your engines are awesome! You inspired me to build one of my own and I am designing another that will be the first of its kind!
im not sure if you’ll see this, but does this require a powerful vacuum? i followed your guide and had a look at other tutorials, and the engine is properly assembled but wont run.. i regularly put water in there to lubricate it when testing and it does the job. any tips?
Water can create friction
For the valve and crank can you use a 1 by 2 axle connector like in the previous piston
Yes I did that
can you make a list of all the pieces? i really want to make one but I dont have the money
just made my own and it works brilliantly :)
I did it in exactly one hour and it works flowlesly. Thanks a lot
Awesome to hear, glad it worked out for you!
I just made the world fastest 3 cylinder SOHC with my new valve design!! I will upload Saturday!
Could you list the parts or make a plan on the site that generate one
I made the engine exactly, it seems like yours spins way easier. I put a strong vacuum to it but it just won’t run, so you know why? Any tips?
your vaccum might be too strong
im having the exact same issue. i built mine exactly like his, but it wont work. it wont even crank.
Sure you used correct colour pins?
What I had to do was adjust the crank timing - I had accidentally made it 180º instead of 90º. Then I put olive oil on the contact areas and added a second wheel to the output shaft and it runs great.

I built it and it works well but are there any attachments you can make to add to it?
You can add thinks like a transmission, a starter, maybe even an exhaust manifold and pipe for cool sound!
Do you got a link on where to get the extra parts like the orange piece on the piston or the yellow half cranks?
Trying to make it but don't have the right pieces could you tell me what the small orange thing at the too left if the parts part is and same with the wheel
The complete parts list is available for download on the Discord Server along with instructions on how to use it to buy the parts on BrickLink.
i made a similar engine but when i get closer to 6000 the piston is moving up and down so fast that it rips it off the crankshaft and it shoots through the top of the engine
try gluing all non moving componits
for some reason when i built mine and tested it witg my vaccum it didnt do anything! any reasons why
U have helped me so much for about a year I've been trying to build a Lego engine
Hi i made this engine and hit 9,000 rpms! Is there any other engines you recommend to build?
Should try to make some engined without the small motor crank (yellow piece crank for valve) I don't have them, and finding those isn't easy
you dnt need them yo can use some spacers and 2 hole little pieces you have to get creative but that will work
You can very easily replace that piece for a 2 stud long one, you may have to adjust the length of the valve connecting rod but it would definitely work. My first LVE on youtube utilized that crank setup and it worked just fine.
Which way does the vacuum suck outward or sucks
