The steel fire-ring broke and the gasket eroded into a coolant passage.

The valves appear to be in excellent shape, as are the bores . . . just an ever-so-slight ridge. Surprisingly little carbon deposited on the pistons, valves, and combustion chambers.

I'm going to clean it up, blow out the crumbs, install a fresh gasket, and he will be ready to go . . . right after an oil change and some fresh coolant.
Congratulations! Thats' the lesser of the evils lurking within.
good deal Mike. I am glad for you that it was nothing big.
Glad to see thats all it was. Better go buy a lottery ticket... :wink:
so far it looks like an easy repair.
check for cracks.
Looks like it was starting on the other side too. To burn through, that is. Don't know flatty's so I can't suggest a solution. I'd investigate........Frank
Glad to hear it wasn't too serious. IT's funny how we will always think the worst, and when it something not so bad it is such a relief.
Good to hear that it was nothing too serious, :D as others have said, check as to why it happened. Hope prestone didn't get down into the oil, as it does not agree with con rod and main bearings

OK, I'll bite! --- So, what caused the BANG?
....hydraulic lock?
....the gasket does not appear to be open to the adjacent cylinder, allowing a cross-fire.
I'm glad to hear things were not more serious.
...Please buy a lottery ticket for me, as well.

The BANG was mechanical rather than an explosion, the sort of hit you hear with an incorrectly aligned Chevy starter. Best I can figure is that it was a touch of hydraulic shock from coolant that had leaked into the cylinder while I was gassing up. The great cloud of white smoke that followed me home was a combination of water and glycol.
I've got my Super Lotto ticket sitting right here on my computer console.
Sounds like it's gonna be good to go. Coax a few thousand nore miles out of her before the Chevy goes in - LOL.

Mike, if that mechanical bang was caused by a form of hydro lock you might want to check to make sure all your pistons travel as high as they are supposed to. The last time I heard a noise similar to that I bent a rod due to rain water getting into #7 cyl on a SBC thru the carb. It made a sort of clink or clank/bang sound.
It may have been a headbolt that lost torque. Torque the headbolt repeatedly until it stays torqued

That thought crossed my mind, George. I just finished ckecking it and it's okay, although in the process I discovered that things are not what they are supposed to be. The fellow I bought the truck from said the engine was the original -- as far as he knew. The original and long-term owner (independent garage owner/operator) has gone to his reward so I can't ask him, but it appears sometime over the years the old fellow slipped a Mercury shortblock into it; it has a 4-inch stroke! :D
That might explain why it's such a strong runner. . .

4 inch stroke. mayb punch the muther out a .100 or so?
Quote from: "Crosley"4 inch stroke. mayb punch the muther out a .100 or so?
I think we'll punch this one out to 3-5/16-inches when the time comes, which will take it to 274 CID. It will be built for a project yet to be determined.
The one that will replace it in the truck is also a Merc that we've bored 0.030 over which will take it to about 261 CID. From the beginning, I spec'd this motor for the truck -- bags of torque, long service life, full-pressure oil filtration, good fuel economy, plus "supercharger ready," just in case. :)
I'm going to port and prep this block as soon as I finish porting and port matching a V12 Lincoln for a customer. That looks to be fun . . .

Would that be a little bit of "Blue Printinting" so that everything appears stock but it runs better than every other one? GPster

That's certainly the intent. It would be interesting to see what a little imagination could do with cam profiles, but that would compromise the Lincoln's smoothness and quiet idle. When correctly built and tuned they're just about inaudible at idle, even with the hood open. The exhaust note sounds like a million dollars, however.
I've wanted a Continental ever since I saw my first one right after WWII. Yeah, I know they're primitive and the motors are trouble prone but they still stop me dead in my tracks every time I see one.
