Hi guys, I'm back from the dead. Since everyone enjoyed this writeup, I'm going to be changing my valve cover gaskets this weekend. Do you want me to do a separate writeup or add it the end of this one.

The part that took the longest was cleaning the area of the brittle wire loom protector that broke off and fell into the hole next to the spark plugs. I got my kirby with attachments and sucked them clean...but some were wedged in there...so I needed a small pick or screwdriver to un-wedge it out. You need to do this before removing the plugs cuz you don't want any of that stuff falling into the hole to the engine.
I bought some new wire loom protector to replace those that fell apart.
Make sure to torque each plug at 13 ft/lbs...spec torque.
