I have an engine in a 1650 that is seized from sitting outside with no rain cap on the muffler. What have people had the best luck using to free up an engine? I was thinking of filling it full of coke pop but a person told me that the acid would eat up the aluminium pistons. Any thoughts? Thanks for any help

Probably depends on what part of the country you are located and whether the engine had rain caps or some protection from rain getting in. I live in the Northeast. Have found that if it will not break loose on a tow you will find something that
looks to some degree like the pictures posted.

I'm with Dick L on this one. If she's full of rain water, I'd expect to see what Dick has in his pics. Probably the most unusual method I've seen to free up a stuck engine was heating it up. A man I used to work for had a G-6 MM that stuck from not being ran, not from rain in the exhaust. He got the idea to connect the heater hoses from a pickup to the cooling system on the tractor. It took all day idling the pickup, but it did get the tractor engine loose.

Here is a story we ran in the Cockshutt Quarterly last year. I have tried this stuff and it does work. If any of you would like to try it and then respond back in this forum with your opinion I would like to hear it. If any one has other questions or needs more information email me and I will do my best to help.

A new tool for dealing with internal engine rust

When we start to work with any old engine, the first question always seems to be “does it turn over?” And the longer that engine has sat it storage or parked under a tree, the more likely the answer will be “No”.

I have dealt with many rusty engines over the years and like every other mechanic or restoration specialist faced with the same problem, I have my bag of tricks. The popular tricks include penetrating fluids like WD40 and diesel fuel.

But, now I have a new tool. It’s called ENGINE RELEASE. It is a fluid that can penetrate rust on the cylinder wall, at the points where the rings and piston wall contact the cylinder wall. If you can get the spark plug out, the fluid can be injected in with the attached tube so that there is fluid all around the top ring land area of the piston.

After one or two days, and a few more ounces of the fluid, most engines will turn over. The instructions claim that it is possible to treat a seized engine, then as soon as it is free to turn, the engine can be started. As the engine runs it will purge out the rust and chemical, leaving you with a usable engine.

When I was first approached to try Engine Release I was sceptical, as I usually am with mystery cures. But I tried it and it did work for me.

To test it I recruited a experienced diesel mechanic friend. We located a 242 Ford tractor diesel engine that had one seized piston. This engine had been stripped down for repairs years ago and the owner couldn’t get one piston to free up, even trying every trick he knew about. So, the bare block, with the one piston and rod still inside, was set outside on a pallet, left to sit for over six years, covered with only an old tarp.

The fluid was injected in, around the cylinder walls, and then we waited till next day. Behold, with only one treatment the rod and piston now could be driven out with a wood block and hammer.

The interesting observation was how the fluid had seeped past the piston and now coated the lower part of the block. The fluid just moves along, working its way through the rust. I perceive that is how it works past the rings and piston wall. The two pictures I’m using below show the fluid being added at the top, then later how it spread down into the crankcase.

The Engine Release comes as one kit per cylinder. Each kit has one can of fluid and a short plastic tube to swirl the fluid around from the spark plug hole (or diesel injector hole)

I don’t doubt that an engine will start right away and it’s worth the try in order to save dismantling. Starting the engine right away, with the release fluid in and around the rings, would appear to be the right time to get the rings free in their piston ring groves.

I got my kits from The cost is $19.95 a kit plus $4.95 S&H, delivery is by mail usually 10- 14 days. You can follow the instructions located at I recommend reading both web sites. Read all the instructions before ordering, to ensure you know what you are going to be doing.

Some of what you can find in a stuck engine. Not Oliver but!

If you have any of this in your stuck engine it will take one powerful magic potion to soak to perfection.

yes for sure it will be a good learning experience. you will find the cyl. will be pitted , and honing wont bring them back. rings will be seized in piston grooves. lots of times the water even corrodes the piston tops. even the head will need work done to it . pull out valves and inspect for pitting. ya just pull it apart and look at everything , then when someone says just soak it you can say ya right. sure there is the possibility to get them running but that engine is in poor shape. its the ones that buy and sell to watch out for. blowby is one thing to look for. good luck.

Thanks Rustred. You confirmed what I was thinking. A person gave me this tractor for the 4-H members to work on and it would be good for them to see what water can do to an engine. Even if we don't get it running it will be educational.

well when it sits out side with no rain cap, better get the wrenches out and start dissasembly. all these majic potions and stories, but they sure dont work for me!sorry to burst your bubble. why would you wait weeks or months on potions when you would have the job Properly done during this time. let us know what it took to get her freed up.

With my thin pocket book for tractors I have bought over twenty with stuck engines. I am no fan of magic potions to free them up. Myself I just want to see every part that has been stuck and why. Most every stuck engine in a tractor that has set out side has pits in at least two cylinders both in the cylinder walls and valve seats. When buying a tractor that was pushed outside two years before was probly brought into the shed for an inspection after setting out for ten of more before being pushed into the shed.
I have lots of pictures of valves and seats from stuck engines. I have bought a couple of tractors that had only stuck valves. Good idea to check to see if the valves will move before spending a bunch of time trying to free up cylinders.

Coke will eat the pistons . Spray Blaster into the spark plug holes first . After a couple days , pour some diesel fuel into each hole & let set for a week or so . It may take more time depending on how seized it is , I had a six cyl locked tite . It took a couple episodes of the soaking & about a months time . It finally broke loose . Do not use the starter . Use a screw driver into the flyeheel to try turning it . HTH !Goood luck & God bless
