If it is going to block up the leak in the head gasket, it is also going to block up your oil cooler. Don't put any of that quick fix crap in your truck.

 

if it will seal the headgasket it will plug the oil cooler. If it does not plug the oil cooler, then it will not plug the head gasket leak. Not worth it.

 

a cylinder to coolant head gasket leak is not something a leak fix would ever target it is working in the wrong direction

it's not a cooling system leak it's a cooling system intrusion LOL

and they clog other orifices like oil cooler passages any minuscule solid will

 

^^ yep, what he said.
All you'll accomplish with a "stop leak" is clogging your oil cooler and possibly your radiator and heater core. The headgaskets leak from the compression side not the coolant side, so it would be blowing out any stop leak that tried to seal the gap.

That's why you need to pour the stop leak in the intake, not the degas bottle! :crazy:

 

You can give it a shot. Then, if it doesn't work (which it won't) all you have to do is remove the engine, remove the heads, pistons, crank, cam, front & rear covers and all of the core plugs so you can boil the bare block and heads to get the product out.

If your didn't pick up on the sarcasm I'm going to reiterate my opinion. NOTHING GOES IN THE DEGAS BOTTLE EXCEPT COOLANT! (except chemicals when cleaning)

 

This is definitely one of those times where, if you have to ask, you probably shouldn't be doing it.

 

This is the only thing I've seen:

Injector Bore Repair Tool

It's a "Cylinder Head Repair Tool, Injector Bore, Ford 6.0L," $645 and "Sealant, Cylinder Head Repair Tool, Ford 6.0L," $24.95.

I saw a write up in DIeselWorld Magazine, and there were a few posts, but since then, I have not seen all that much. This kit will only work in very certain instances. If you read the advertisement, it will talk about them. If you have questions about this, call BPD about it. They are upfront and honest and will tell you if this is not for you.

My uneducated opinion, is if this worked in a wide variety of instances, then everyone would use this as preventative maintenance.

 

You're basically stuck with what I'm facing right now, replace head gaskets, have head mpi'd for cracks, valves checked, deck planed flat if it isn't. UCF Machine Shop - Precision machining, engine rebuilding and more. Cummins + Ford Rebuild Specialist.
Had a pretty lengthy discussion here the last couple nights, was convinced by several knowledgable members of these forums that that is what had to be done, so I went to UCF for their remanned heads.
