OK, i dont have aluminum heads, they're stock E5s, with stock equivelent Autolite plugs and Motorsport 8mm stock replacement wires. I'm in the process of just doing a tune up, but untill then i'd like to figure out if there's some other problem that's causing this.
It's backed out 2 times in the last 10 or so times i've driven the car, causing a pinging/ticking noice that sounds like my motor is about to fall apart (which takes about 3 years off my life each time i hear it)
I'm not tightening it by torque specs or anything like that, and i'm not tightening it any less than the other 7 plugs, so why just this one plug?
