I had someone give me a f150 several years ago with a stuck 302 in it. I wasn’t in a hurry to mess with it so I drained the oil and refilled the engine with diesel fuel. It held almost 9 gallons. I left it for a month then came back to it. I drained the diesel and removed the spark plugs and started working it back and forth with a breaker bar. Twenty minutes later it was free and spinning over with the starter. I put a new set of spark plugs in it with a new filter and fresh oil. I’ve put 40,000 miles on it since. Engine runs great and doesn’t leak or burn oil.
No it doesn’t. The engine I was talking about was a gas powered 302 Ford v8. The diesel fuel just helps free the rust and lubes the engine somewhat. Think of it like a large amount of pb blaster.
I'm glad to hear this. I was given a boat today that the guy said just shut off one day and the motor locked up out of nowhere. The motor is a 302 ford and I was looking at videos to see if anyone ever freed a 302.
@@michaelgriffin3730 Is the motor fuel injected?
No it has a 2 bbl carburetor
@@michaelgriffin3730 usually when it just shuts off it’s something catastrophic

Lol love it.
😂
That's a mechanic🤷😂😂
I like reading the comments but OMG u weren't joking
😂😂😂😂😂
When I was 16 or 17 I ran my 76 Camaro out of oil ( it leaked about a quart a day out of EVERYWHERE ) and seized that 350 up tight as a drum.
My Grandpa ( who warned me about 100 times not to buy the car while we were looking at it ) had me pull all the plugs and shoot Liquid Wrench down the cylinders everyday for a week.
Unfortunately when we put a 2 foot breaker on it and tryed to turn it over, it didn't happen.
My Grandpa tryed to save my butt on that one.
Even though I ignored his advice to the point of making him mad at me when I bought that oil derrick !!!
Haven't thought about that lesson (that was over 30 years ago) he taught me in a long time.
Thanks Uncle Tony.
Great freakin video.
Glad you got that old Dodge motor free.
Yeah, stick em that way and they are gonna need some parts and machine work. Much different from trying to unstick a good runner when it was parked that has just seized up from condensation attacking a motionless engine for too long.
Great video. My old man freed a big block Chevy once with 24 volts to the starter 😂. Also remember being a young lad and dad’s 3.8 V6 G body seizing its engine on the highway. He poured a quart of oil down the carburetor and it got us home! Really thought my dad was a wizard after that one.
It’s nice having all that room to work in. Those were the good ol days
It really is. Trying to work on my girlfriend's HHR is so cramped compared to my Jeep
Filling cylinders with diesel helps. We used to use a 2x4 cause it did least damage to piston tops. 16" 2x4 and a 2 lb hammer - thud, thud, thud ...
It's absolutely amazing how well a stuck old engine runs with valve job, decent gaskets, and decent re-assembly :-)
I watched this video a year ago and I would like to say thanks. I bought a 1967 GTO HO convertible with a stuck motor. LOL. I followed your technique. Took over a month to get the pistons out. The car sat for 40 plus years. So I now have a rusty, 54,000 miles, AC,4sp, original hood tach. I am the second owner. Motor should be done soon, the car, well not so fast. Red with a white top and white interior. My 7th and probably last GOAT. Thanks again.
Just wanted to say Thank You for just taking the time to show people things that could save them a lot of not just money but stress and aggravation. I appreciate you
"I hope ya got something out of this" Yes, I get something out of every UTG video. Keep 'em comin. :)
Yes sir, if only I could say this louder without being obnoxious.
Hey can someone help me? I drove my Honda Civic for MILES AND MILES with no oil. It started making grinding noises and kept dying. There was no oil. What do I do now. I have to save her!!
Another great video. It so nice to see someone . Inspecting and addressing the problem instead of throwing it away and replacing it . The method you showed is the way I was taught. Pull the heads and intake that way you see that everything is moving and nothing is in a bind .
Excellent description of how to use finesse to avoid damaging a save able engine. For myself I always use brass only brushes to clean the bore especially on very rusty engines. Then gently hone down to the piston tops using a vacuum to prevent any debris from sinking to the rings. I also use an oak disk to transfer force around piston head to prevent mushrooming. But you still may have to use direct strike for exactly the reasons you stated. Your description on technique, how and why to do it is educationally perfect! and will probably help people save engines. Great Vid.
Hey Uncle Tony, thanks for the tip. I watched this the day it aired, tonight I got froggy enough to test it on my 1970 CJ 429. Yet here I am half an hour later with an engine that rolls over again!! THANK YOU SOOO MUCH UNCLE TONY. BROTHER, YOU ARE LEGENDARY. (YES, this is ment to be a yell at ya from excitement!!)
Thanks Uncle Tony, I just trailered home a 63 vailent convertable that's been in storage since 95. Ive known the car and owner my whole life. The storage unit was flooded at one point and water got in the crank case. the motor wont turn. Going to drain the case, pull the head and start soaking the cylinders tomorrow.
Thanks for all the 225 slant six videos, my first car had one and I'm stoked to have one again after all the code chasing involved with modern cars.
Thanks for sharing your knowledge Tony!
Uncle Tony I actually pulled up one of your vids to help a friend today fix his car now my friend is a subscriber lol this TH-cam community is making anyone mechanically inclined a better wrencher thanks UTG! "The point setting vid"
Cool!
Unca' Tony saved a roller small-block Mopar LA v8 from the shredder!
What years were the roller motors?
@@mikeobrien3744 318 started in 1985 . 360 started in 1989 pickup and finished its run when the magnum motor started. The 360 la roller motor is getting harder to find because of the limited time period it was built.
Mopar v8's got 'em in 1985, per allpar.com + the small-blocks (and 3.9L v6 / ancient slant6 replacement) got "The Magnum Treatment" starting in 1992-3 while keeping the roller cam system.
Love pb blaster good stuff . My dad & I use to use a drill & spin the oil pump to help lube the motor . It's crazy the stuff we do for fun
Thanks Tony! You are a great service to me and a lot of people. You explain things very well. Thanks again!!
Learned more in this video than a few hundred hours watching other TH-cam channels!
Thanks man!
Never underestimate the value of a good shock with a hammer. Those sharp blows can save a ton of work. I found my brother fighting a tie rod end once. I showed him how you give it a whack on the side and it generally falls right out. He said he'd been beating on the top for half an hour. I learned that trick years ago for freeing up stuck bolts, lug nuts, etc. Along with penetrating oil tapping things with a hammer helps a ton. Also if it doesn't work you already have a hammer to hit things with if you're the type to lose your temper in those situations.
Amen brother, anytime I’m knocking suspensions loose, smack it in the side once or twice....comes right loose
Really good stuff. Thank you! I have a stuck barn find Rover 90. Been sitting since 1991 and so very much appreciate you sharing that no nonsense approach.
Rocking back and forth will reveal other issues as well. Scoured pistons that cause Piston slap, for example, can be identified using this method. Great informative video!
First mechanical video ive seen where you get to the point and give real info and troubleshooting theory. Subbed
Thanks worked like a charm I usually let the motors set with atf in the cylinders to loosen them up but have had a 400 from my 78 d100 setting for a few months and it was still stuck so I tried this yesterday and she turns over freely now
Hope you, the Mrs, and whoever else you care about had a great Christmas !
I taught my 7 boys who are now old enough for wrenching how to "Shock" my 76 chevy k20 that had been sitting in the trees for 16yrs. I had the oldest pull me down the road and I dropped the clutch.... I bet my boys would be "shocked" to watch this video.... I was "shocked" watching this as well.... I loved it and I will use your technique on one Im gonna make them work on. Take care thank you.lol
Good video Tony, I use the same "shock' treatment for frozen bolts on wheel cylinders etc.
Not sure if this is why my mustang seized in 5th gear but I’m sure this info will help a lot of people out there. Thanks for the tips
THANK YOU, THANK YOU, THANK YOU!!!! 🙏
you have no idea how much you helped me
I was banging it with wood and broke like 6 4x4. Once i watched this video i did what you said and magic happened 😊 🙏🙏🙏
I learn something on every video UTG produces!
Thanks for sharing your wealth of old school knowledge with us Tony.
Great information man. I never thought to free an engine this way. Thanks for the vid
Hi uncle Tony and Aunt kathy happy Christmas and a happy New year love from the UK 🇬🇧🥂🍻🇺🇸🥂🍺🍾🍻
This is an excellent video. You do a great job of making mechanics understandable.
Reminds me of working on cars with my Dad as a kid. Thanks Uncle Tony.
Excellent video. I'm going to do this on my 5.4. I'm glad I found this.
When I was growing up, I learned something very important from my dad about working on engines. If it doesn't work, beat it with a hammer and call it a bunch of filthy names. Eventually, everything he did that to started working.
This is useful to know. I have a 53 chevy with an engine that's hard to spin. I put penetrating oil I each cylinder (forgot about it for 2 weeks) and was able to turn the engine just slightly with a breaker bar.
Step 2 for me is usually warming up the block with a torch, gently, not too close and not too crazy hot. I've just had too much good luck heating to the point where the clearance i'm working with changes by a couple of thousandths. Along with some penetrating oil and something substantial to spin the crankshaft i usually do ok at getting them unstuck.
Thanks for the video tutorial.
Right or wrong, the trick my dad taught me when i was young for this: before you pull the heads pour brake fluid in the spark plug holes and let it soak a couple days then see if it'll rock free with the breaker bar back and forth.
Your way seems more responsible to avoid cracking a ring and you see the condition of the cylinder wall before you start.
Just though i'd share how I learned to mess up the paint on my fenders as a kid.
You are a blessing i was having this issue and your method worked. Thanks for this man
TH-cam recommended does it again for the win.
Another great video. Since I found the channel I keep watching these. I have a 1993 TBI that I love and keep on the road. Newer than what you work on mainly, but it's making me want to buy a project car. :)
My old man has a ram charger just like that even has the same wheels on it he drives it almost every day good ol ride
This is a life lesson learned the hard way.
Thanks for sharing!
Uncle Tony looks like the kind of Uncle that will have some pretty awesome and badass stories to tell, the ones you'd be proud to relate to your friends
Another great video Uncle Tony! PB Blaster works pretty good. I use it, Kroil (Aerokroil) & MoPar heat riser solvent, for those tricky jobs! Can't wait to see that Ramcharger running again! Be safe!
Buddy we did what you said and it worked!! We watched the video and we were like 'pfft no way....". Took a block of wood, sprayed some pb blaster in the cylinders and put a bit of torque on the front bolt. 1 tap each cylinder and she slid like nothing. Thanks!!
I've taken the heads off of a old 327 it was stuck. I dumped a little marvels mystery oil on top of the pistons left it sit for a day. An a pipe an hammer had it moving in about 5 mins.
I just used your method to get my 62 Mercury to turn - thank you
Damn I have been doing it wrong. I fill the cylinder with Marvel's mystery oil, let it set for a week. Then put "Bertha" the six foot pipe wrench on the harmonic balancer then a little left, a little right, a little more left, ect.ect. if Bertha don't make it move it ain't moving.
Your way is a lot quicker and easier.
That's better because it will soak in between the rings and then with every little movement it will lubricate that section of cylinder wall!!!!
we did it like that to a mustang I had. guy left the aircleaner off and the tent it was under had a hole. filled the cylinders with water. engine was pretty seized. I actually put trans fluid in there and i don't remember how long i think a day, and a neighbor came by with this HUGE concrete prybar and we put that over the breaker bar and freed it. never smoked either.
I've always used Marvel Mystery Oil down the spark plug hole. Never had a problem. Never had to take the head off.
I call my bar the Y-COB ,your coming off bitch , bar
I love it. I have 76, 87 ram chargers and 81 440 crew cab, 95 zj, 2-2011 wk2 grands, 05 300c awd.
Out of all penetrants I've used over the decades, that Phat Bitch blaster is the hands down fucking best!!!! Glad you freed her up and saved it!!! I fucked up last 440 I put in my 72 barracuda,I didn't change the freeze plugs and in late Sept.got a freak cold blast from Canada over night that dropped temps from the daily 70s into the fucking 20s!!! I only had water in the block and just dropped the 440 in a day before, cocksucka froze and cracked so bad it wouldn't start. Back in the 80s I paid $50 for that car,ah the good old fucking days!!!! Anybody seen my time machine laying around?
I was given a truck that my uncle left the spark plugs out of the engine long enough for condensation to lock it up. The borescope showed the lovely rust right at the low spot of each piston head. PB Blaster 2 day soak, shocking down each spark plug hole with a piece of rod stock and then a pry bar on the flexplate gear teeth back and forth. A ton of leverage is produced with the flywheel or flexplate. Only AFTER the engine has broke free.
Dude that's slick! Great video as always!
Happy new year uncle tony !!
Thank you. I’m working on this very issue on a 1969 351w. Everything looks clean so far but no movement. I’ll remove the heads like you suggested.
Hi Uncle Tony! I’m a 60 year old gal that loves working on my own vehicles- I recently acquired a CJ 5 Jeep that’s been sitting for 25 years- I’ve been soaking it for a month- working with it everytime I walk by! Nothing- I removed the head and got a nice pipe like yours- I’m going to get that a try now- your video has given me hope- fingers crossed ! Thanks for your video 👍🏻
Did it work?
I had some moron try to tell me one time that I was going to bend the rods and break the pistons I was like "Dude these things get 3000 PSI of Pressure in a matter of a millisecond when it's running I'm sure a small tap is not going to hurt it!
I had another moron tell me that it's impossible for a car to shock you because 12 volts is not enough.
I told him to place his hand on top of the Mallory Cap
Tell me how that feels
I didn't tell him that the alternator was running at 120 amps..
Lol
He had third-degree burns on his palm. And he smacked his knuckles on the hood when he ripped his hand away.
(Its never the VOLTS- Always the AMPS that kill you!) I taught him that.
@@thecloneguyz well arnt you just a very nice person 😂😂😂
Thanks for the info. I literally just unstuck my seized ls 5.3 doing exactly what you said. Thanks again
What u did because my truck suck now to 5.3
Yukon
Thank you for posting this! I'm about to do this with my 2006 F150 with a stuck 5.4 3v.
Real honest genuine guy. Cool.
New favourite channel.
I tried to free up a stuck engine around 1980 or so. pulled the heads off like you did, but a piston was turned sideways in the block. intake valves and pistons don't always get along.
Uncle Tony is The Man
Thanks for the info UTG Fam!
Great tip on saving the motor especially shock the pistons. 😎👍👍👍
Had a 6 foot bar on the crank bolt. No budgie.
Pulled inspection cover and pried on the ring gear. It moved. This was a dodge flathead. It now runs!
40 psi oil pressure.
Thanks Tony, I have a Chrysler 318 that is stuck and I'm going to try this on it!
good info, i am working on a stuck ford 460 so looked for some advice, also i answered a craigslist ad for a 460 distributor, was $20 the nice guy gave me two for free!
Thanks, your method worked perfectly.
I did learn something thank you
Good to see the point made - DON'T TRY TO BEAT THE PISTONS THROUGH THE GROUND UNDER THE CAR.
Keep it up, U.T.!
This had more critical parts than a nuclear strike.
Nice one big yin I’ll have a bash at my engine next week, thanks and all best from Edinburgh 🏴🍻
You are the man! Very helpful video
My old man did the same thing, I’ve used this method no problem.
Time to pass the torch to the next generation
This man spits straight knowledge
Thank you for the explanation I have a engine Oldsmobile 307 stuck
i am told to put anti-rust liquid WD40 in the spark plug holes
but hitting the pistons is faster!!!
Excellent vid I have a 77 f 350 ford with a stuck motor
Got to love the old PB blaster 🤘
Marvel Mystery Oil! All of those penetrating fluids suck, IMHO.
PB Blaster is the best. I have used it for years.
tarstarkusz when I got my 1971 Buick GS for my channel I let it sit for two weeks with my Marvel mystery oil in the cylinders and that stuff works amazing. I think it works better with the heads on it where penetrating oil works better without the heads
Used to love it until I used Seafoam Deep Creep, my new favorite.
Roy Graham I will have to try that
Thanks Tony! Great video with instruction. Gives me a starting point with my '75 Dodge w200. It's been sitting for 8 years. Gonna see if it is
or isn't locked up. It was running then with no problems. But has sat 8 years with hood open. ;(
It's just locked I'd say Carol, Pls try doing what I wrote in my post
just tosses the cigarette into the engine bay, haha
Thank you very much, very wise way to free the engine.
The technical phrase that you were searching for 🤔is ,"Dynamic shock load "crazy uncle Tony. 🤓
Breaker bar on the main pully too.. This and marvel mystery oil is what I used on vans and motorcycles pulled out of fields and briar patches.. Probably not the best way but it works. Light soak on the pistons an hour or more, then burn it off using starter fluid and a clean fuel supply.. One summer I got paid to get a whole field of second gen econolines running that had been sitting decades
Good point on the shocking method.
I seen some Canadians on yt trying to get an old Buick straight 8 loose, they ended up machining up an o-ringed "lid" and hooking up a hydraulic hand pump to try & move the stuck piston loose...but man, that thing was STUCK, I don't think even this would have worked there.
FYI they ended up drilling out the piston, jb welding the cyl.wall and finding an nos(!) piston locally
Thanks Tony i have a 350 i have to free up! It had water in it but not for too long. Just long enough...
I used Liquid Wrench 45 years ago to free up a lawn mower engine, It does work!
Uncle Tony, as always a good clear informative video. I think you're wonderful and love whatever you do for us! I'd like to suggest that when you make videos, please don't speak for about the first few seconds of filming. It always takes the youtube audio broadcast about that long to catch up with the video and produce sound. With your videos (others too) I always have to back track to hear what you first said. If that won't work for you, a standardized intro of music and maybe photos or something will serve to get the audio portion working for when you speak. I'm sure other people have to back track too. We love you so much that we have to hear every word you say. God Bless and Happy New Year to You and Uncle Kathy.
Great tips Uncle Tony!!!
Really helpful stuff here. All anyone ever told me about engines that aren't running is"bar it over. If it doesn't move, you don't want it" or they would say " if it doesn't move, you HAVE to rebuild it" which obviously is not always the case. It's good to know that there actually is a less expensive way to get an engine unstuck than a full rebuild. That might be what some of the people who have "survivor" cars do. That category of car is kind of annoying because it has to have a certain percentage of original paint, and certain amount of the motor has to be original without a rebuild and it just annoys the hell out of me.
My dad, who worked on cars from the late 50s till he retired (heavy equipment/diesel mechanic) in ‘97 said they used to pour some Marvel Mystery Oil in each cylinder (just a little bit), let it sit for a week, and it almost ALWAYS would turn with a little help from the breaker bar.
They’d drain the oil, and dump a few cans of kerosene right through it, and fill’er back up with fresh oil and a filter.
Provided it hadn’t been internally damaged, they always said “it’ll run. Drive it. When it likes for good, we’ll worry about it.” 😂
Learned a ton from him (he doesn’t do this stuff anymore at 78) and I’m grateful for it now!
Your a good man for this
I just pulled the head on a 1982 ford 6. The engine is seized from sitting for 20 years so your tip on shocking the. Piston Rings I will try, THANK YOU!
Absolutely love those core plugs where the bellhousing is
Just broke free my buddy's engine. It was locked up due to sitting after a badly blown head gasket filled the cylinders with water (bent valves too). I pulled the head (4cyl work truck) and had machine shop do valve job and resurface. Broke free engine after soaking cylinders in transmission fluid! Took about a week of trying everyday after work until one friday, of course on friday, it let's go! Reassembled engine, fired it up with fresh fluids and it's running great! Spent about $300 on machine shop bill, new fluids and a brand new radiator. It was more fun than work. Kind of like a ln experiment. We'll see how long it lasts haha!
We recently got a hole case of cheap penetrating fluid from a local parts store, and boy does that stuff work good, had a Briggs powered tractor that was stuck BDC, just filled up the cylinder with the spray and next day she was spinning
Performance VW diesel and lacquer thinner and some atf in metal oil can don’t get on paint !
Great video Uncle tone
Nice work. Good communication skills.
I’m going to try this method on my 440 story block thanks
I like the sheet over the front, easy to get tools that fall behind the radiator
