This is after I've tried to dimple it in with a punch to try and make it easier to extract. But as you can see, the part has a very thin wall at this point, most likely due to corrosion.

Using some creativity, I used a chisel to split the remaining piece in the block. That turned out okay but it also pushed it into the hole. Then using a pair of needle nose pliers, I managed to distort the remainder and pull it free of the block. Just

Once everything was out of the hole, I used a Dremel with some Scotchbrite pad and cleaned it up.

Once clean, I took the new part, coated it with CopperCoat then hammered it into the hole. Looks pretty and should last until I take the engine out for a complete overhaul some day.

While I was in there today, I took the thermostat housing off. I'll be shortening the tube and needed to get it out. This is a shot of the brass washer used in conjunction with the thermostat to block off the recirculation port when the thermostat is fu

Here is the thermostat fully closed in the cold position. It's hard to see the additional "Hat" pressed on to the thermostat plug, but it's there.

Using a screwdriver to hole the thermostat open a little, you can more clearly see the "Hat" on the bottom. This is supposed to contact the brass washer in the block to stop flow through it the thermostat is totally open. Does it? Let's find

The old block out of the Mach I (the one waiting for the autopsy for several years) has the same kind of brass washer in the block. This one looks unhealthy but it's the same size. Note the thermostat "Hat" that is supposed to block the hole.

Whoops!!! It fist right through the hole, that can't be good. Or rather, maybe it's fine, but it's not going to really stop anything.

Here is another shot, inserting the thermostat plug from a different direction. I can't really see how this did much good at all.

Okay, so here is a bunch of crap on the outside of the tank. It looks like just drips but it's kind of crunchy. I have a feeling it's hiding a pinhole.

Moving around the outside a bit, we find more indications of what -might- be pinhole leaks, bubbled paint and spots of corrosion.
