Cracked Willy's L134 Head
Is there any value to a cracked Willy's L134 head? It's leaking water into the oil but not sure where the crack is. I did try replacing the head gasket before replacing the head and it still leaked.

Hi, there is no oil in the head, the leak must come from somewhere else.
A cracked head could blow gases into the coolant, or coolant into the cylinders.

If you are sure the head is cracked, toss it, you can buy a run of the mill used one for a hundred bucks.
look over the head with a magnifier, it should be clean if you tried a new gasket on it, look for a fine crack or get it magna fluxed, $50 at least plus any cleaning or sand blasting of it. Maybe if it is an early head somebody might take a chance on it. Need numbers and pics.
I dont know how it would leak water into the oil, leak would have to go through the cylinders and cylinder rings or through the valve guides and there would of been evidence of rust or hydro lock.
There could be other reasons it leaked too, that we dont know about, like maybe the second time you used sealant on the head bolts or studs and didnt the first time, or maybe the engine sat for months the first time you did it and the gasket seeped, or ????????

I'll have to call a Mulligan on that one. Darn I hate working on something and then having to leave it alone for months. So there's no path for oil in the head? That would mean even if the head gasket were to blow that the only place water would have to go is into the cylinders. Well it was something obvious then that I can't remember now, so may be that head is still good. Whatever is was I either fixed it on purpose or by mistake because I haven't had an issue with water in the oil since.

Cracked Jeep heads will allow coolant to leak into the cylinder and down into the base. Fling it and get a good head. Have it Magnafluxed to confirm the suspected crack.

FWIW,
I knew of several people making art ( lamps etc) out of Willy’s heads. Try to sell it cheap before you scrap it.
