Oven, then freezer, repeat a bunch of times and sometimes the expansion/shrink cycle will brake things loose.

I'm not sure a propane torch can get enough heat into a cylinder to make much difference.

And I don’t care to open up another email account just to post a few pictures. Post one picture, get 1000 spams, ....nah.

I don’t think the whole engine will fit in the oven. It is a big single so it is a tall engine, beside, with all the oil residue on the engine the stink of fried oil in the kitchen would not make the wife happy. I have a 1000 degree industrial heat gun and a oxy acetylene torch so I have access to plenty of heat. Tried both and no luck so far.

Id probably be at the stage where I take a chisel & hammer to the piston. 1/2" from the rings is probably a good place to start chiseling.

Well actually instead of using a hammer and chisel, I was thinking of drilling about a 1/2” hole at 90 degrees off the wrist pin axis at 11 and 1 o’clock and at 5 and 7 o’clock and then using a hack saw and cutting the piston to the cylinder wall as far as I could probably having to stop when I got to the underside of the rings. Then use a drift and BFH to knock out the wedge created and hopefully the reduction in surface area would work things loose.........I hope!

I am not sure what to do with that information. When I click on a icon to post a picture it asks for a url. I do not have a picture posted on a image hosting service, I cannot post one I have on this computer as it has to address me thru my email address and it stops doing anything as soon as it sees “pacbell”

Just to -get- a place on this website some administrator has to do some trick to get me on BARF at all. If you know some trick, let me know.

Adapt a harmonic balancer puller (or other handy gear puller) to the head bolts/studs and use something like a plate or block to distribute the force across the top of the piston. Apply pressure and continue to let sit in oil. Use a torch to heat until the oil starts to smoke then let cool. Apply more pressure with the puller. Repeat process. You'll get there....
The slow, continuous pressure works better than single, hammer impact. Try to apply the pressure evenly so the piston isn't side loading in the bore. You could also try to drill in one spot on the edge of the piston, into the first and second ring land. If there are two rings and the top one is sealed shut you won't get any penetrant into the land between the two or down to the second ring (maybe why it is being so stubborn).

Keep upping the ante until physics kicks in and you go ". . . .well, that was interesting, I wonder if the recycle truck will take it."

They used to. I got rid of a Toyota Corolla 1600cc I-4 back in the 90s in Walnut Creek. We used old style baskets like the Post Office uses. A little bit each week. The recycle guy was picking up the most recent basket with the crank and flywheel in it. He said; "I've been watching each week and looks like you don't have much left". I told him just the block but it won't fit in the basket. He said to leave it by next weeks bin and he'd take it.

On that note, I hope Dogfeathers doesn't have to go that route. I thing we're all rooting for you.

Perhaps similar idea as freezer but in opposite direction. Heat everything up super hit and toasty. Then dump dry-ice on top of piston. Then really give it a good smack!!!
