Dandy Dave Posted October 28, 2022 Author Share Posted October 28, 2022 (edited) Actually the King Midget used a one cylinder Wisconsin. Anyone could have adapted a two cylinder in one also I suppose. Edited October 28, 2022 by Dandy Dave (see edit history) Link to comment Share on other sites More sharing options...
Restorer32 Posted October 28, 2022 Share Posted October 28, 2022 Years ago we were hired to get a '33 Cadillac V12 running that had not been run in many years. This was not our first rodeo so to the displeasure of the owner I insisted on removing the heads just to see if everything looked OK before we tried to start it. Passenger side head and block looked great, nice and clean, no ridge at the top of the bores. Driver's side head a different story. Laying on top of piston #2 were several shards of glass as if someone had broken a champagne flute. Now, these shards were too large to have entered thru the spark plug hole. 2 questions. #1 How did those shards of glass end up on top of the piston and #2 What would have happened had we tried to start the engine with that glass in there? 2 Link to comment Share on other sites More sharing options...

lump Posted October 29, 2022 Share Posted October 29, 2022 So, I assume that using a top-quality body-filler to patch that piston, and then filing new ring grooves wouldn't work in this case? Have you considered making a new piston out of some top quality hardwood? 1 Link to comment Share on other sites More sharing options...

She plans on putting that stone up on the hill someday when she picks out the right spot. He shot himself and 50 + cows around 13 years ago. I'm on the farm that started the, "farmers and suicide" story. It's a long story that I will not get into here as this is not the place. But he did want a stone like this. It reads, He never met a person he couldn't charm, Acerage he couldn't farm, Fish he couldn't catch, Deer he couldn't bag. Mad Mountain Dean 59yrs.

Had one years ago with a cracked piston skirt. Edited October 29, 2022 by Dandy Dave (see edit history) Link to comment Share on other sites More sharing options...

Flivverking Posted October 29, 2022 Share Posted October 29, 2022 Not Ford,(no/rod dip pan), pan too long for a 4 banger compared to piston size. Link to comment Share on other sites More sharing options...

I started this thinking that more photos of broken pistons, and possible causes would show up, but then folks wanted to know what the crushed piston came out of. So here we are. 1 Link to comment Share on other sites More sharing options...

intimeold Posted October 29, 2022 Share Posted October 29, 2022 (edited) On 10/12/2022 at 10:54 PM, Swear57 said: I agree with avgwarhawk definitely detonation. I have seen this many times over the years. Yes what dose the block look like? Sorry, detonation did not do this. Look at the angular damage, there are sharp detents down into the piston. That piston came in contact with an immovable object; between the piston and cylinder head. That is crush damage. We have worked on thousands of engines in the shop. And doing a lot race car and motorcycle engines; that really turn the RPM,s, this was common. But this old engine probably never turned a high RPM. A stuck valve, broken off valve head, a valve seized in a tight valve guide, broken valve spring, or a foreign object entering the combustion chamber did this damage. Here is how you can tell if it was detonation: Excessive heat caused by advanced ignition timing, or a lean burn mixture are the 2 most probable causes of detonation. The piston would have heat damage, melted aluminum, burn holes through the piston. Go back and look at that piston, no burn holes or melting. The damage is angular crush damage. If it were overheated the piston would show melting damage. I can probably find some denotation damaged pistons in the shop. I went to the shop and this is the first piston I picked up. Notice the aluminum is melted, the combustion flame overheated the piston and at the weakest point, it blew past the piston ring and melted the top of the piston, which allowed the piston skirt to be overheated. Detonation can ruin a piston very quickly. But the angular damage to this poster's piston was done by an object not heat, not detonation. We do this work everyday and see al types of damage.
