V10 spark plug thread repair
Hey all! I'm working on repairing the threads of a blown out spark plug on a 2000 F250 V10. I did the first one just fine utilizing the Calvan tool. In my haste to get to the next one needing to be done, I forgot one of the most important steps...step 1...close the friggin valves!!!
So, I have drilled and tapped the hole, went to blow out the shavings and at this point (when there were any shavings coming out of the hole), I realized that I hadn't bumped the motor so that the valves were closed. I guess I was fortunate that the cylinder was down at the bottom and didn't do damage to the cylinder, but now I need to deal with the issue of the aluminum metal shavings in the motor.
My question is, do I need to just pull the valve cover to clean up the shaving or do I have to pull the entire head?

Those shavings getting blown out with the valves open is one thing. Possibly nicking a valve with the tooling (to bore the hole) is another possibility. Have you looked inside the cylinder with a camera/borescope?
Regardless, for piece of mind, I'd pull the head (and intake) for inspection and cleaning. While I was in there, I'd inspect the other spark plug threads too and/or put inserts in them while I've got the head off. Not sure where you're at with mileage, but perfect "opportunity" to inspect/replace timing chain / guides / tensioners.
