Porous block or tiny crack?

So... Not freeze plugs, not head gasket...pin prick leak from the block! I'll try to get pics but I put dye in and the ran a pressure test. It held the pressure but after wiping down the block I saw the tiniest pin prick leak. About 4-5 inches aft of the freeze plug on the passenger side and a few inches lower. Might be a crack, but if it is it's tiny. Ah, 360k miles but perhaps her race is run.

EDIT: lol, so then I find a nice used 1998 green ford ranger 2wd right down the road. It's a 3.0 so I guess I'll enter the timing cover gasket club. 195k for $3,000 though? I sense a haggle in my future.

If you like the truck and it's otherwise in good shape, it might be worth trying some Bars Leaks in it before giving up. It would be hard to justify a major repair at that mileage.

Tell me if this makes sense:

I'm going to flush just my radiator and pull the thermostat.
I'm going to fill with distilled water and some bars (copper).
I'm going to follow directions.

Then? Do I use a complete flush? Just the radiator from time to time? Do I leave it in?

I can wait to put the thermostat back in until it's going to get cold.

fwiw my heater core is tip top, no leaks blows hot.

But doors and windows. A 1998 Ranger that's identical just posted for 3k, but it has the 3.0 and is an automatic. I may just get that after I patch and sell my current girl. Sad though.
