I'll post a few more closeups.

Sounds like a soak in some penetrating oil will be needed, then some more wailing with the mallet. Might be worth checking in with the classic car thread over on >>>/o/14157392 as well.

You think so? I was concerned that I might end up bending/shattering the valve stem. As for that thread, I'll give it a look. Thanks.

If you're swinging your mallot like Thor swings Mjolnir then yeah, you're prolly gunna damage something, but gentle taps should be ok. Just soak the bastard for a full day with pen-oil (hit it every few hours as it dries out) and see if it plays ball. If it has rusted properly into the guide that might mean a new head, but I don't much into cars, so someone else might have better advice if oil doesn't unfreeze it. I know you can heat components to crack them loose but considering the mass of metal you'd need to heat around the valve guides (plus the fact it's effectively a giant heat sink) i'm not sure how practical that would be.

Try some penetrating oil inside the port where the valve stem comes up. I reckon a smooth hard wood board on top of the valve then tap it with a regular hammer. Rubber is a bit on the soft side for this.

Can you turn the engine yet?

>new head

This thing is an old side valve so its the block they are in.

No shit? I have never seen that configuration before. How would one go about re-machining the valve seats if and when they wear? Surely blown seats =/= new block time?

It depends how far gone it is as to how much of the following is actually needed.

Side valves went out about half a century ago, in cars at least.

Lots of stuff in this one too but 13:00 is where the cutter comes out.

Well I'm a fucking idiot, those and OP's are just flathead engines which I know about, I don't know why it didn't click before. Great videos though, thanks for dropping.

I'll give it a shot. As for turning the engine over, I haven't been able to do so. I plan on totally disassembling and cleaning it, honing the cylinders (though I haven't gauged them for roundness yet), lapping the valves (a grind may be necessary), replacing the piston rings, and inspecting/replacing the bearings.

>disassembling and cleaning it

After you have cleaned things like the crankshaft put a layer of fresh grease over it, specially the polished surfaces to prevent rust wile you are taking your time on the rest. A quick re wash to remove the grease then oil them just before assembly. Put all moving parts back in the same place even if they seem interchangeable.
