As mentioned under technical, I am 99% certain ive blown a head gasket. The signs are there, so its just a matter of confirmation by JC when he can. Question is, what do I do now? Do I fix the motor (shown 350k) and how much will that cost me (I do the work mostly), or do I buy another used 3.5 if I can source one, or do i just part out the Rangie?

Ive spent ( as we all do) way too much money on it already, and thinking I need to spend even more so is really not an option. So how much do you think I can expect to get the Rangie running again with the above scenarios? What would be the better option?
