Need Insight for 7.3

Blew a head gasket I'm guessing on the freeway today. Water poured out of the exhaust with white smoke/steam.
So what are my options? Rebuild vs new block? Would like to do it once and right the first time. Thanks corey

Update: Oil seems to be free of coolant/water or i could say that the oil is not milky

Injector cup gone bad?

Baker42 · Jan 25, 2016

Drain oil
Drain coolant
Pull heads
Have them milled flat
Replace cups while heads are out, maybe 910's and pushrods
Install new OEM gaskets, studs!
Fill with oil and coolant with a new thermostat and drive.
You can get it done for about a grand. Good luck and GO BRONCOS

ill check that out! only a G? Just pulled the fuel filter and the bowl was mainly water! Injector cup replacement? finger crossed

Don't pull the heads unless you HAVE to!

is the raidiator going to be ok if fuel is mixed in with the coolant?

Magnum PD · Jan 25, 2016

Drain it all out, put a flush solution back in the cooling system, drain, then fresh coolant.

So no? I believe fuel has been slowly mixing with the coolant or vice versa for some time now and im sure thats not a good mix for the thermo/rubber/plastic. Its pouring out of the exhaust like a soda fountain now. Maybe its not the cups?

Pull em. Not that bad dude, unless you feel like not knowing 100%. BTW if a gasket is gone south you will have to. Injector cups are rare failure. Can it happen? Sure. It could be the oil cooler, also rare to mix oil/coolant. When a cooler fails, you usually will just see oil under it on cold mornings. If it was my rig, Id pull em and seal them up like new.

Out of the downpipe

Just kinda unusual for a head gasket to go. But that looks like it.

There's no coolant in the oil. I think the gasket is fine. loose injector or bad cups hopefully. fuel bowl was mainly water

What do you mean by having them Milled flat? I'm working on the removal of the heads
