It works, but just make sure you rinse the whole thing and the block out with a solution of baking soda and water to neutralize the acid from the vinegar or it will immediately flash rust again.
Old gas tank on an Isuzu Trooper had a ton of surface rust from sitting for several years, dropped the tank and filled it full of vinegar and left it in the sun for a day, after drained it out and just using a garden hose and sprayer nozzle all the rust and crap came out, tank was shiny inside. Rinsed it, filled it with water and baking soda to neutralize any vinegar left, drained it and rinsed it and let it dry out. All the rust issues were gone. Cost $30 for the vinegar and was totally worth it. New pump in it and works great.
You can do the same thing by jacking up a working car, tractor, portable cement mixer, etc - anything that rotates slowly - and strapping the gas tank to that and then pouring pea gravel in it halfway and then sealing it shut. Then let it spin around for several hours. The gravel will help beat and scrape the rust off. Neighbors will hate you, but it works. Then wash it out or take it to a shop and get it re-coated as needed (the exposed metal will continue to rust when exposed to the petrol and will leech rust into your fuel)
Great video. I have some slight rust in the cylinders (probably come off during honing), but the main concern is the rust in the gallies. If I can plug them off I can definitely consider trying this and/or solutions that are more aggressive. If the engine is light enough after I remove the crank and all that, I’d prefer electrolysis or hot tanking/boiling.
this is exactly the video i needed to see. i have a buick 350 that got doused in hurrican harvey. its full and the pistons are rusted in. was rebuilt before the rain so it has new pistons i wanna use in my old build so this looks to save them. sweet!
It works it works thriggen good awsome video mate done my boot in my car and everything else in my seized engine i use a wire brush to take crystalized rust spots outa the boot after the vinegar reacts and finished its dryed made a crystal layer east to remove
People make all kinds of concoctions and buy lots of products like Marvel Mystery Oil but nothing works as well as plain white vinegar.Its cheap and environmentally friendly.Thanks for this great video.
Cool stuff, look up the 55 gal drum with large Bag to clean rust off these old Blocks, I will do the bag & 55 gal drum with Vinegar & let you know how it worked out. Thank you
It really does work thanks for making this video I just did a LS1 engine and it got all the rust out of the cylinders car had been Ina flood and intake went under water
I did not rebuild it one cylinder was pitted bad and was unable to save it but I will say it didn't have any rust after this but u need to use a good vinegar I used two different kinds and the one from the dollar store that was pure worked best and all rust was gone in 2 days
The only thing is that you have to be careful with vinegar because not only will it remove the rust but also a few layers of the metal. I left a knife sitting in a bottle of vinegar overnight to derust it came back the next day and there was a deep line etched right where the top of the vinegar and the knife met and the knife was slightly thicker above the line below it it was now thinner all the way to the tip
Vinegar also destroys anything rubber. If your engine is this fucked to where you need to dump vinegar in it you will be replacing the rubber and lines anyway with new (you should) but just keep that in mind.
Something else I'll toss in, if you can't get a cylinder head off, put away the hammer. Find which cylinders are at TDC, release the rocker arms so the valves are on their seats and pull the spark plug to fill with compressed air (even a bicycle pump if need be). so long as the cylinder passes leakdown, she should pop for you. you may even want to keep the head bolts on loose to keep it off the floor :)
It might really be a good idea to try this on a seized engine to unseize it enough to remove the pistons or remove the pistons while not being to harsh on the rings. But if not, I just don't really see why anyone would do that... I mean, the cylinders will never be good after this... You will still need to hone them after that if you don't want to destroy the rings and/or consume a ton of oil...
This will work perfectly for my light surface rust they dont have water in them just rusting from the moisture in the air not gonna drill em out unless the rust was severe enough to eat into the metal
I use a $15 ebay hone and it does about 40 cylinders before it wears out. A must to get good crosshatching and remove pitting. If the pitting is really bad then the cylinders will need rebored.
Hey Thomas, very good idea on cleaning the engine with vingar never thought of that.. BUT UR DOING A BIG SCREW UP BY PRESSURE WASHING THE INSIDE OF THE MOTOR.. THAT INVOLVES WATER AND WATER WILL CAUSE THE RUST TO COME BACK NO BRAINER THERE!!!!! U need to use a little steel brush or Emery cloth with gasoline for that NOT MORE WATER 💦
I’ve done this to a few motors now, I clean it with vinegar multiple times pressure washing it between each bath. But I remove the pistons and all then set the whole block in a bath of vinegar over night and wash it, once I get it where I want it i use a leaf blower to dry it and I spray it over with an oil & fuel mixture. Learned it from another channel.

But you didn't re-seal or re-line the tank??
Just did this to my 350 before I saw your video I was amazed how good it worked
Haha i thought this was an inline 4 engine til the end of the video. I was womdering what u meant by “the other side”.
Lol same
Man imagine the damage if it was xD look at the firing order of the pistons! More than one would have been bent xD it fooled me too

how long did you let it work per side?
It works it works thriggen good awsome video mate done my boot in my car and everything else in my seized engine i use a wire brush to take crystalized rust spots outa the boot after the vinegar reacts and finished its dryed made a crystal layer east to remove
Thanks man, this will come in very usefull to many working on their engines and machines.

Also try electrolysis with washing soda, there's a vid out there showing how its done
It really does work thanks for making this video I just did a LS1 engine and it got all the rust out of the cylinders car had been Ina flood and intake went under water
I thought LS1s had aluminum blocks? Or are they sleeved or do some have iron blocks?
Did you rebuild after all that or just straight back in?
I did not rebuild it one cylinder was pitted bad and was unable to save it but I will say it didn't have any rust after this but u need to use a good vinegar I used two different kinds and the one from the dollar store that was pure worked best and all rust was gone in 2 days

I always wanted to know about cleaning the passages to the water jackets?
Thomas bain good evening take care and have a great day 👍
Thanks 👍

You deserve a tons of likes
I used this trick on my girl and it worked like magic.
Thanks for sharing. I will try my buick 215. 🤘🏼

You will still need to hone them after that if you don't want to destroy the rings and/or consume a ton of oil...
i know it's kind of randomly asking but do anyone know a good site to watch new series online?
@Marco Roy flixportal :)
@Deacon Enoch thank you, I went there and it seems like a nice service =) I really appreciate it !!
@Marco Roy No problem =)
Obviously you'd need to hone afterwards. This just helps if you need to get the pistons out and don't wanna crack a ring land.
Well I know how I'm cleaning the old chainsaw engines I just picked up!
People it works.
This will work perfectly for my light surface rust they dont have water in them just rusting from the moisture in the air not gonna drill em out unless the rust was severe enough to eat into the metal
👍🏻
You would still need to hone or oversize tho. I did use on rusty nuts, they were so corroded they literally disintegrated.
airborneleads1981 4 stroke combustion is the best honing tool I’ve used
I use a $15 ebay hone and it does about 40 cylinders before it wears out. A must to get good crosshatching and remove pitting. If the pitting is really bad then the cylinders will need rebored.
Curious can you use this a fuel additive or is there a way to use it without removing the head?
Do you think it’s safe to let the whole head sit in vinegar on a tub ( container)
you didnt show if it unstuck the pistons??????
Interesting experiment.
Muriatic acid works well too, just caustic.
vinegar is what i use to get parts to rust and look rustic
Did you run this motor after
cider vinegar works better. I used both over the years, tough jobs, you want to apple.

How long did you leave it in, Hoss?
aprox 3 hours
I will applicate this vinager for cooling systems to clean rusty hoses ? Do you recommend ?
Use wire wheel acid it works in 2 mins
You can simply use a rust converter, it will take 15 minutes to wipe that rust away.
Sweet hack bro adding it to the list!
Were you able to get it freed up?
Works better to add salt to the vinegar
And some deep-fried battered cod 🐟 😁
Did it loosen up to where you could turn it over?
I found an engine which had rusted for 15 years, It is missing the cylinder head, Do you think it will restore my engine a lil bit?
Man that's not good to have the head off for so long
Shall we clean printing machine cylinder?please guide me
Awesome!!
i hope this works
Those clinders need to be honed.
What about adding baking soda
Next time try muriatic acid it works in seconds but use breathing protection for the nasty fumes.
what the you materiall cliner
You should try brake fluid
Would this motor still need to be sleeved?
No just a good honing.
Bye bye wall clearance
Should i use distilled water when neutralizing the acid from white vinegar along with the baking soda?
Water is water in this case! Thanks for watching!
He sounds like Pete Davidson
Hello thomas, is there any way i can personally contact you?
Is that a 4.7 PowerTech ?
Will the rust come back?? You are using acid
Brand new
Next time try Apple cider vinegar works much better
Badass
