Reading through the posts I have found several ways to free a stuck engine. Which way is BEST.

Some say turpentine, others diesel, PB Blaster, Free All and kerosene. There has to be one that works better than the others.

Which is best, and why?

I have tryed about all the home remedies and the motor I was trying to free up wouldn't budge. I even put hot water (starting with warm and went hotter a little at a time) in the water jacket, in the top and out the block drain. I could hear the metal expand but, no luck. Come to find out, when I tore it down, the wrist pins were rusted solid to the piston. I guess what I am saying, if the rings are the only thing stuck, you are lucky. This motor sat for almost 25 years with the exhaust open. PB Blaster, Marvel Mystery oil and diesel fuel are all good. Wish you all the luck.

I had an old IH flathead that I poured Marvel mystery oil in and walked away from it. I topped the cylinders off once a month for about 3 months and it loosened right up of course the cylinders had to be smoothed back out but it did allow me to remove the pistons.

If tincture of peppermint won't do it, give it up!

I have used both turpentine and pb blaster they both seem to get in the tight rusty areas faster than the rest. I like them both and use them both.


Best wishes

I have tried everything. Gasoline, kerosene,diesel,pb blaster, you name it.
None of them have ever led to an easy turn with the crank. A 20 lb sledge and a tree limb the size of the diameter of the cylinder will ususally do it.After that I go to a long brass 1 inch rod and beat the
pistons out from the bottom. Some come out in pieces and others come out with the sleeves. There never seems to be any rhyme or reason to it.
At this point I think dynamite might be the way to go.

I had been trying to free a Lister stationary engine over the past few weeks and tried putting various things in the cylinder : WD40, paraffin, petrol, cellulose thinners. Nothing seemed to penetrate at all. Last weekend I put some petrol in the cylinder and set it on fire which seemed to put a little bit of heat in cylinder. I don't know whether that helped or not. What did get it freed was a lump of wood and a few bumps with a 14lb hammer. I didn't have to hit it very hard but the weight of the hammer seemed to do the trick. Soaking it is first thing to do but I'm inclined to think that if it is really stuck there will be no substitute for appyling some force at some stage. Doing all you can to minimise the force needed and applying it in a way that minimises risk of damage would be the trick. Although I got away with a bit of 2x2 I think getting a piece of wood sized to fit the bore neatly would be the best way of avoiding punching a hole in the piston. I would give no one any guarantee about being able to free a well stuck and rusted piston without damage. Hope someone else has mastered the art and tells us what to do.
