The cooling system was apparently neglected. I drained and flushed the coolant and what i drained out didn't look bad, but i ended up having to put a heater core in it because it was nearly completely clogged. https://www.ford-trucks.com/forums/1...placement.html
Shortly after I sold it to Joey it started pressurizing the cooling system and randomly puking coolant.
It appears to us the gasket was corroded away and the result was leaking combustion pressure into the cooling system. Possibly into the crankcase as well.
Joey is going to go ahead and replace glowplugs, do head studs, hpo boss plugs and all the other misc items while apart.
I cant believe this truck ended up doing this, I never would have expected it and i guess it goes to show how important cooling system maintenance can be.
What are yalls thoughts? look like a gasket failure to you? I think this was also causing the shake at idle.
Out of curiosity, is that the correct head gasket as it seems the water jackets are blocked off. Thought that was unusual. Also the crush ring on the gasket looks like it may have been damaged on installation and squashed in towards the valve. I have seen them blow outwards or have cracks in them but not bent in like that.
Just wondering if a previous owner has attempted a head repair before.
It seems to be original type I’ll send a pic when the new ones come in. Also the hg seem really old so not sure unless it was early on. No idea how that was pushed in towards the valve unless damaged during the assembly in the past. Wish I knew the history from the owner Chris bought it from.

From what i saw i never seen a sign of heads having been off, couple of the injector orings were definitely original and ate up as well. #1 was the worst

Step #1...build garage with suitable headroom for twin post lift.
Step #2...purchase and install twin post lift.
I have a nice pole barn with roof trusses and enough headspace, I’m thinking that should suffice. Only question is, will they support it? If need be, I could support them around the work area.

A small time dealer around here is one who only has one street corner.
The FSM has these sections regarding the cab. Supplemental instructions and diagrams would be required for items like steering shaft, heater core lines, etc...
The link i posted is from the tech folder
it was combination of write up i found online with some things i added in . I think there are still a few minor things missing
