Clear today, plugged tomorrow.

Yeah that's why I was asking, the crappy part is the potential damages from a plugged piston cooling jet aren't a very promising prospect either.
I was kinda thinking like the head being replaced at 500k miles, maybe the piston jets get replaced too as a precaution. That's the only thing I could think of as a remotely acceptable level of risk.
