Keeps puking out the tank when it gets hot, I know this is a possible and most likely head gasket, but could it be any other thing? Money is tight unfortunately.

Unfortunately for you it's 99% head gaskets. Don't feel bad I was laid off in feb and can't do anything. But collect unemployment and wait til someone wants to hire me and my trucks sitting in the drive way and has been for the last 3 months with blown head gaskets.

That's what I was thinking, but another question, I heard the black Onyx gaskets were suppose to be "the best" but research says they aren't as good as they say... What is "The best" gasket?

Unless your ready to drop about 3-4 g's fire ringing your heads the only gaskets to use are OEM head gaskets.

I also heard about machining your heads, just stick with me here because I'm still learning and looking forward to being a diesel tech in the near future, the heads are factory warped and you can send them in to be machined flat?

yes, anytime you pull the heads it is recommended to have them machined for that reason. Also the Black Onyx head gaskets are pretty crappy, it is usually recommended that you just put Ford OEM gaskets on, plus they have perfect fit, ive also heard Black Onyx dont have the "exact" fit. just my .02! Hope this helps Reezy71x, good luck on becoming that mechanic, theres alot to learn!

You can only machine these heads I think no more than .005 or .05 one of the two. then they are out of spec and the valves will hit the pistons. if they have already been decked and turn out to be warped than its most likely gonna need replaced with new heads or used heads that are in spec and can be machined within tolerance. But when you rip it apart make sure the heads Goto a reputable machine shop, have them hot tanked, magnafluxed, pressure tested, and decked to within spec if they are not completely flat.

Okay, one of the guys i use to work at the dealership with, now at a mulch and rock place, opened his own diesel shop and he specializes in diesels. I get to work with him with the repair, but i've heard that you can fire ring them?

Don't worry about fire ringing your heads unless you have boat loads of money for head work and supporting mods. You don't need fire rung heads unless you are running huge injectors with insane amounts of boost.
