Sir ,Im 64 years old, Been working on cars sense 12 years old, Did my first engine rebuild at 14, And I don't mean rering cheap job, Fitted ring grinding ring to fit, Ported and polished heads,Gauge all bearing, Now I have freed up lots of motors, Some frozen 60 years, Oil does not work, Brake fluid works best, Let it sit 1 month, If the car is standard, 95 % Success rate, Pull the car 40 mph Pop the clutch in 4 th gear.It has freed every motor, There was a ford 3/4 ton sat in woods 40 years, Frozen from the start, Thats why was parked and forgotten, 2Months I left to soak in Brake fluid, First Pull Pop free, Started and drove home 40 miles, So taken apart the Motor every time, You don't have to,, If the Car is worth 70, thousand, It should be dismantled anyway, and rebuilt, There are chances you take, could Brake a rod, bend a valve, but most of the time, it comes free with no Damage, Just trying to Help.
I've got a 59 mercury y-block that is seized. The guy who had it before me pulled the mechanical fuel pump off and left it for 4 years. Do you add the brake fluid just through the plug holes or or do you dump some down the carb too? Thanks!
@@CanadianBriar Yes/also add Transmission oil /and even a Little diesel fuel Let it sit ,a week, keep bumping the starter every once and a while. It will free up.
@brianbloom1799 thank you for your response and for the information. What do you think the odds are that one of the crank bearings is rusted rather than a piston? The spot where the mechanical pump was removed and sitting open is right at the front of the engine. When I look through the hole I can see the timing chain and part of the crank. I'm in Canada, so this truck has an inline heater for the winter that warms the coolant and heats the block. I've been heating the engine once or twice a day using that. My thinking is that the pistons and block will expand and contract at slightly different rates and hopefully help the rust to crack a bit allowing the oils to oenetrate deeper.
@@CanadianBriar A good way to free up a seized motor is with XcelPlus: It bonds a lubricant to the metal... so even if you have some scoring it will protect it against excessive wear or seizing. 🙂
You said, pull the car 40 mph and pop the clutch. What do you mean by that? If the engine is stuck or frozen how can you drive the car at 40mph? Thank you.
I've done the same but advocate getting the offending piston(s) smoking hot with a torch prior to whacking. Rings seem to release from the pistons sooner. Otherwise put it back to gether with clean oil and fuel and run it hard for a couple hundred miles. It should wake back up if it's going to.
saw that video long before I posted. I am a Master Automotive Technician (former FL LEO too) who had already tried everything in the video you refered to many years before that video was posted along with a few other chemicals not tested in his video too. @@Ratridez
Worth noting when using the vehicle itself to try and free an engine, you want to be in your highest gear. First or reverse puts the engine at a huge mechanical advantage over the wheels, or rather the wheels at a disadvantage. Higher gear gives the wheels more usable torque over the crankshaft. An overdrive gear is ideal, because when backdriven it acts as an underive. Don't know what gear you were in, but I know most people will make the intuitive assumption that you want your *lowest* gear engaged and that's unfortunately incorrect.
Can't tell you how many UA-cam channels find an old engine (in or out of car) and they immediately see if it will start. Those are channels I never watch again. They are amateurs and for sure they cause damage to the engine cranking on an old dry engine. I restore vintage motorcycles and I always at least pull the valve cover, spark plugs and check for broken parts. Then I use PB Blaster to free up any sticky rings and let it sit with oil in the cylinders. Will pull the head if the engine won't turn over. Sometimes do a quick hone if the cylinders need it. What you found is usually what I find as well. A bit of rust and carbon build up. If still tight, I end up taking the engine apart to check bearings. But easier to do with a MC engine.
Some cars you can slip the bearings out without removing the engine. On this engine you cannot remove the rear main cap to check the crank bearings without removing the engine.
If there is a corrosion issue freezing the pistons you need to be careful. Even when the engine breaks lose, sometime the rings will freeze in their grooves or within a portion of their grooves. As the engine warms up, the pistons will expand on one wall of the cylinder and can freeze up badly. If you have any doubt, pull up the piston, check the rings and clean grooves as needed. If you remove the rings, do it carefully and put them back exactly the way they came out.
I've done that a few times using transmission fluid sometimes WD-40 before they had blaster it may take a couple weeks but you have to be patient. Remember put it in 4th gear absolutely do not use a hammer. Patience is a virtue.
Steve -- You're one of the Best "How-To" guys on the Tube. Showing Us Noobs things we would never think (block & Hammer) about trying. Definitely "not your first rodeo." Thanks So Much for Making these vids.
Time to disconnect the banjo fitting for the oil pump and fill the pump with fresh oil, check oil level and see if oil pressure will come up. Well done Steve! Cheers from Texas!
I have done the same with the wood in the past. If you had not tried it I was going to suggest it. It doesn't do the engine any harm as long as you are not too agressive! I am sure it will be fine to put it back togethe now as the bores look ok. Thank's Steve, I always like these sort of videos.
This is helpful Steve. I recently acquired a 20’s Nash with a seized engine. The head is already off and it’s been soaking for a year or so in diesel. The cylinder walls look no worse than the Sprite. I think I will give this trick a try.
The engine looks good and I'm sure it will be fine. There is less back ache when working on these engines in a Mini, but other than that they are exactly the same. A new head gasket and it will be running. Well done Steve.
I have been a mechanic since childhood and professionally for fifty years, in my experience "penetrating" fluids do absolutely nothing unta=il after you've got things moveing, I have seen bolts soaked for weeks in these mirical products and when you finally shift them the threads are still as dry as a bone, I still use them though, it's almost a religion. By the way, I've freed off loads of engines by the hammer and block method, they are usually ok.
Love these types of videos, very educational and gives confidence to go for it. How handy is the borescope, right? When you need it, you need it. And it's not like in days past where you had to be a specialist to own one, borescopes are SO inexpensive nowadays, yours is a nice scope from a brand name, but cheapo scopes on Amazon are what $20? $25? And they work just fine. Mine connects to my phone, fits right down into pretty much any engine. I've used it on my weed whacker engine, lawn mower, Sprite, Midget 1500, Jeep wrangler straight 6 etc and then turned around and stuck it in a hole in the ground to see who is home and works just fine each time.
I have watched many videos on freeing stuck engines, the prevailing trend is to soak things with penetrating oils of various kinds. That will be needed eventually but if rust or other metallic corrosion is the problem and it usually is, penetrating oils don't measure up to the task of breaking up those bonding agents. Success always comes down to leverage in the right place, heat if possible and an agent that actually attacks rust and galvanic corrosion, then there is a need and use for the various oil solvents for lubrication when moving the stuck parts.
Good video. Before you remove the rocker arm shaft you should have looked to determine which cylinders were on the intake stroke. Tapping on those would have yielded better results. Also you should have thoroughly lubricated the cylinder walls before hitting this starter. Just my two cents worth from 47 years of restoring classic cars
@johnw6498, I have an old Ford with 55k miles on the odometer which has a 351C and has been garaged and not started in 35yrs. What should I use to spray the cylinder walls for lubrication through the spark plug holes before turning the engine over? Should I fill the cylinders with Mystery Oil for a few days. Is that oil thin enough to travel past the rings? BTW, I do have one of those snake cameras which I can feed through the spark plug holes.
@@Phantoma3 You need to research what to do. Any light oil would be good enough for the cylinders if the engine fires up immediately. However, you need oil in the bearings, on the timing chain, on the camshaft and on the lifters. You can pump oil around by pulling the distributor and using a drill or some other tool to spin the shaft that drives the oil pump. Or, you can crank the engine with the starter or spin the engine with an impact wrench. With the spark plugs out. I have seen videos where someone apparently dry starts an engine that has been dormant for decades. Again, you need to research the issue until you understand totally what you are trying to accomplish, and the cylinders are only part of it. Another pitfall is that there are lot of Dr. Doom types out there who make things excessively complicated and warn you about what will happen if you do not follow their convoluted protocols.
@@anonymike8280 Thanks man, it never even crossed my mind to first get the oil pump squirting oil over the lifters, camshaft and timing chain etc. I want to make sure that everything is lubricated before trying to start it up.
@@Phantoma3 @Phantoma3 Talked to a friend of mine today and he said, take off the valve covers and pour oil over the rocker arms and down the pushrods. This, he said, would lubricate the lifters and get oil onto the camshaft. You should be ready for some oil leaks after it gets running. In that long a period of time, every gasket could shrink. Unfortunately, the rear main bearing seal could be leaking too. The engine itself undoubtedly is as good as it was the last time it ran. Then there's the transmission. It could leak too from the pan, the front or real seal and even the dipstick tube. Don't forget the differential either. It could leak from the cover or the seal. Then there are the axle seals. And, of course, the cooling system. There could be wiring that has deteriorated over that much time. Then there's the fuel system. That could have leaks too. So could the carburetor. There could be a lot to do.
Great job. My slant 6 is stuck. Old owner said there was water in the oil so I'm just gonna pull the head. Hopefully it's not junk. Thank you for the video
I have added a 20% vinegar solution to a seized motor(water entry) & when I checked later there were shard’s of rust sticking out from bore wall.(I had removed head).I will vacuum out deposits then add CRC(anti seize thread conditioner) & hope for the best. Good luck with u seized motor but I think u indicated that the piston was moving with the use of HAMMER & importantly block of wood. Cheers, Cliff, Wanneroo,Western Australia
For freeing up stuck engines oil won't penetrate down along between the pistons, rings, and cylinder walls. A good penetrating fluid that works well and is cheap is a 50/50 mix of acetone and atf. White vinegar is a bit slower, but works well, it also removes rust. Store bought versions work well, but cost more. PB Blaster is a good one for the money. WD-40 is a waste of money for this job.
Marvel Mystery Oil is not an oil like you would think of. It is Methyl salicylate (oil of wintergreen or wintergreen oil) which is used in a lot of different fields but is used as a penetrating oil to loosen rusted parts especially engines.
Your patience and perseverance were the keys to unseizing that engine.Those concoctions they sell are useless and costly.Plain white vinegar is the best and cheapest rust remover on the planet.Its also friendly on the environment.
seized engines are tricky .! I have found that if the engine is/was know to rotate . I have heated fuel oil , careful, not to allow the fuel oil to BOIL . This causes the piston (Aluminum to expand breaking the corrosion around the cast iron block and the piston. Then you can do your mystery oil treatment and not have wasted time.
Wow you brought back memories of myself working on Boats back in the late 90's.. We had a 4x4 piece of wood that we called the "Mercury Tool" to free up frozen engines.. Too Funny.
I had the same problem with a tractor engine (had water sitting in the cylinders for quite a while and wouldn't move at all) soaked the cylinders with vinegar for a couple of days then oil for a day and used a block of timber and steel plate using the head bolts to create a makeshift press (took about 30 minutes of rocking it back and forth using the makeshift press and it freed up nicely) it's running quite nicely only needing an oil change
Rings could be rusted in place to piston in compression (particularly the multi piece oil rings). You should use a PB Blaster soak to free them up a bit.
Called an Ultrasonic Processor. Very expensive. Would also decarbonize the listings & ring grooves. I've wanted one with a long probe to insert into a plug hole, but again, many thousands of dollars for used ones in the scientific fields.
Ive had 3 seized engines in the past, I oiled the cylinders, set for a couple days, then pulled the vehicles with a chain, dumping the clutch in gear. All broke loose.
Boil some 5w30 oil till it’s about to ignite and tip in the bores after it just starts to cool turn the engine over works evertime dangerous but works great never flat spot a shell or bend a rod with hammer and wood heat expansion contraction even a few times till it move without a hammer 👍🏻
Great video, guys; thanks. But once an engine is unstuck, are there not rough rings inside the cylinders where the pistons stopped? And are the piston rings not a little messed up? Thanks!
No not necessarily you would be surprised how little it takes to stick an engine. Also you have to consider that in this case it is on a car that probably won't see more than 500 miles a year.
On a water cooled engine, would circulating hot water through the system expand the cylinder bores by enough to free a stuck piston.... Assuming its not a bottom end or crank ptoblem?
Fab video, really enjoyed it 👍 great to see shared knowledge from a professional. Any chance you could have a flow up video as you prepare and run the engine 🤔
This is great, I’m working on my MGB and it’s in the same state. It’s like you’re working on my engine! 😊I have been squirting Marvels in all the holes for a couple of months while I work on the floor pans. Hope I have as good of luck. 👍 P.S. were you rocking it in 1st gear?
When you added the marvel mystery oil in at the end of the video- did you let that sit for a while or just continue to run the starter and let it get into the pistons?
I think he’s done this a few times. I’m pray my Willy’s breaks lose tomorrow. It’s been soaking and diesel fuel an automatic transmission fluid for six months..
You can make something close to it in your country with 75% Mineral oil and 25% White spirit mixed together. This is the product marvelmysteryoil.com/collections/gasoline-engine/products/marvel-mystery-oil
If my memories of the "A" series motor are correct, they usually had facilities for manual starting handles. (In the land of dim winter evenings and Lucas dynamos, not totally unnecessary, and within the arm power of mere humans.) Does the Sprite not have the cog, or is the radiator in the way?
The front crossmember that the steering rack mounts to prevents you from getting to the crank pulley. The engine has to be taken out or jack up off the motor mounts in order to turn the crank.
@@johnquilter7620 But a completely different chassis. You gotta be careful with the Minors, I ripped a hole in the bottom tank of the radiator with the starting handle on mine. DOH
I got a truck one time and that the motor has been sitting open for 12 years it had wasp nest it had grass growing in the cylinders and I never thought it would spin again I did some cleaning and soaking for a bought a month and she turned over I pulled the motor out disassembled it and took it to the machine shop they had to burn the block to get the rest of it out of it she ran really well then she dropped a valve so yeah lesson learned never trust valve springs that has been sitting for long time thankfully it was a 4 cylinder no big Lost but I did loose interest after that great job on the free up
Derek at Vice Grip Garage would not only have already freed the engine and is on his way home 900 miles away.

"Distilled White Vinegar" works almost instantly. Marine Technicians use for the same use too.

Well done steve these engines were the best and it is great you share your knowledge with us
Rings could be rusted in place to piston in compression (particularly the multi piece oil rings). You should use a PB Blaster soak to free them up a bit.
Hint, use 50/50 mix of ATF and acetone.
Acetone will find its way through and carrie the oil with it.
Atf and acetone works
So does diesel
Mmo works the best imo
Shake it up good. They don’t mix well.And acetone evaporates quickly so only mix it when you need it
That was kick-ass! Glad you freed it up.
One suggestion brother, gloves! 🙃
_Mirabile dictu._ Miracles never cease.
Nice work Steve! Looking forward to hearing Barn Sprite 3 fire!
It seems to me there ought to be an ultrasonic probe that could immerse in the oil - or whatever fluid of choice.
Called an Ultrasonic Processor. Very expensive. Would also decarbonize the listings & ring grooves. I've wanted one with a long probe to insert into a plug hole, but again, many thousands of dollars for used ones in the scientific fields.

Boil some 5w30 oil till it’s about to ignite and tip in the bores after it just starts to cool turn the engine over works evertime dangerous but works great never flat spot a shell or bend a rod with hammer and wood heat expansion contraction even a few times till it move without a hammer 👍🏻
Great video, guys; thanks. But once an engine is unstuck, are there not rough rings inside the cylinders where the pistons stopped? And are the piston rings not a little messed up? Thanks!
No not necessarily you would be surprised how little it takes to stick an engine. Also you have to consider that in this case it is on a car that probably won't see more than 500 miles a year.
@@ThisWeekWithCars Ah, thank you
You know if oil leaks past the rings its a bad cylinder because the rings seal the air in the chanber.. the cylinders are lubricated from below.
On a water cooled engine, would circulating hot water through the system expand the cylinder bores by enough to free a stuck piston.... Assuming its not a bottom end or crank ptoblem?
Ah yes ...Marvel Mystery Oil with the addition of Steve's Wonder Wood ! 🤣🤣🤣🤣
Sounds like the girls would go crazy! 😛
I’m looking forward to a follow up video to see Barn Sprite #3 as a runner. Interesting “break loose” video.
First time I have seen it done that way, very interesting and a good way to save the pieces.
Good content, always enjoy when Steve uploads new content. Always informative.
Another GREAT VIDEO Steve !!! Keep e'm com'in !
Fab video, really enjoyed it 👍 great to see shared knowledge from a professional. Any chance you could have a flow up video as you prepare and run the engine 🤔
Nice little bug Mobil, that engine dosent look like it's done many miles, thanks for the video, all the best to you and your loved ones
Could this work on a 3 cylinder motorcycle?
Great content, keep it coming Steve.👍
Thanks, will do!
Interesting, with the wooden block directly onto top of pistons!
What gear do you typically use for rocking the car to get the pistons to move?
It was in 4th gear that time so that I could utilize all the traction the tires could give me.
This is great, I’m working on my MGB and it’s in the same state. It’s like you’re working on my engine! 😊I have been squirting Marvels in all the holes for a couple of months while I work on the floor pans. Hope I have as good of luck. 👍 P.S. were you rocking it in 1st gear?
What gear are you used? To avoid ruining the gear box you should use only the direct gear, the 3rd i guess
did these not have provision for a crank starter?
Remove head..and crank...tap pistons downward using large block of soft wood
When you added the marvel mystery oil in at the end of the video- did you let that sit for a while or just continue to run the starter and let it get into the pistons?
I would avoid hammer and pour hot oil into cylinders. It will creep past piston and rings.BMC rings wear to a point or split into pieces.
love these ond English sports cars
A great result Steve.
Berapa lama waktu yang diambil sehingga piston benar-benar bebas?
Put a magnetic oil pan heater on it, and leave it on for many days. Heats up the engine and allows stuff to flow.
I think he’s done this a few times. I’m pray my Willy’s breaks lose tomorrow. It’s been soaking and diesel fuel an automatic transmission fluid for six months..
Hi what is that oil i live in europe never seen it here any links? Tks fantastic
You can make something close to it in your country with 75% Mineral oil and 25% White spirit mixed together. This is the product marvelmysteryoil.com/collections/gasoline-engine/products/marvel-mystery-oil
❤ many tks again
are you going to dingel ball hone it before re-assembly? might be a good idea.
If you’re not removing the pistons, does that not risk leaving abrasive material in the cylinders where it can do more harm than good?
Why didn’t you keep lubricant in the cylinders ?
I used Marvel Mystery Oil and Liquid Wrench. When it soaked through I whacked it with a big fence post.
And how would you free the engine if it rests at TDC?
Have the valve seats been hardened on this one?
nice work Steve.
Nice job Steve
Brilliant channel. I love learning new stuff every time! 🇦🇺🏳️🌈
How can I freeze up Renault kwid engine?
If my memories of the "A" series motor are correct, they usually had facilities for manual starting handles. (In the land of dim winter evenings and Lucas dynamos, not totally unnecessary, and within the arm power of mere humans.) Does the Sprite not have the cog, or is the radiator in the way?
The front crossmember that the steering rack mounts to prevents you from getting to the crank pulley. The engine has to be taken out or jack up off the motor mounts in order to turn the crank.
@@ThisWeekWithCars Thanks for the explanation.
Hand cranking can be done on a Morris Minor which uses the same engine.
@@johnquilter7620 But a completely different chassis. You gotta be careful with the Minors, I ripped a hole in the bottom tank of the radiator with the starting handle on mine. DOH
Winning like Mr Sheen!!
Will you be selling this little beaut, or will you keep her? Great job!
Selling it
@@ThisWeekWithCars Good luck! I love those little MkI Sprites. We have a '70 MG Midget MkIII. Would be nice if the Midget had an older sister LOL!
Looks Good. Fingers crossed.
Awesome video man. Lots of fun ❤
So what is this red oil exactly? Why not just some good old transmission oil ?
Great video
MMO is entirely different stuff than ATF. All red oil isn't the same.
Really enjoy your content, keep up the good work.
just a thought: a block heater?
I got a truck one time and that the motor has been sitting open for 12 years it had wasp nest it had grass growing in the cylinders and I never thought it would spin again I did some cleaning and soaking for a bought a month and she turned over I pulled the motor out disassembled it and took it to the machine shop they had to burn the block to get the rest of it out of it she ran really well then she dropped a valve so yeah lesson learned never trust valve springs that has been sitting for long time thankfully it was a 4 cylinder no big Lost but I did loose interest after that great job on the free up
Good demonstration
One step at the time, there vil always happen something to the end..👍🏻👍🏻😄
Thanks for sharing
Back in the day i used atf . This never failed me. Lucky ?
