The Restoration of VIN 4363

Wow that is very dirty for that many miles.

I agree. When it did run, it was very rough.

Does anyone have some advice as far as next steps are concerned?

You can hit the liners with a hammer but then this happens (from a severely corroded junk block):

That oil sludge is not mileage dependent, it is someone going a long time without an oil change and then parking the car for a decade or so. Pretty common.

Is it normal for the liners to stay put when tapping out the pistons? I thought that they were very prone to coming loose whenever the heads are off.

Normally they pop out. Sometimes they don't, depends on corrosion. You can tap on them lightly and it shouldn't take much to get them loose. On the broken one above it was a block that was going into the trash as it had been full of rainwater forever, and I wouldn't give up.

So i guess it's safe to assume that I should budget for new pistons and liners, especially if I end up marring the liners with my hammer? I don't know how resilient they will be.

Does anybody know what items should ABSOLUTELY be replaced and what can be cleaned up and re-used when putting a motor back together?

Update: I managed to get the liners free by hitting them with a hammer back and forth a bit. Funny thing, I noticed a large amount of a substance that looks a lot like sand toward the bottom of the cylinder liners. I'm not quite sure what it is. I will post pics when I get home from work.

Silicates from old dried out coolant.
