PSA: tried a $22 Amazon borescope on a misfire instead of pulling the intake
My 5.4 Triton had a dead cylinder and a compression test pointed to the valves, so I grabbed the cheap camera and found a bent pushrod in about 10 minutes through the spark plug hole. Anyone else using these things for diag, or do you still pull the valve cover out of habit?

Guess pulling valve covers is for suckers now.
