This month's winner is 71 years young, and still turning a wrench!
"I have found that when removing spark plug boots from older engines (without damaging the wires), I attach a needle nozzle to my air gun and stick it in between the wire and the boot," he explains. "Then I shoot air to it, and the boot and plug wire will blow off without damaging either one."
One way to avoid the problem in the first place is to apply a dab of dielectric grease when installing the boot. It may save the next guy the trouble! But hey, thanks, Dave, for taking the time to share your tip — and congratulations for being selected this month's winner. Your Mitchell 1 prize is on its way!HONORABLE MENTIONS

I found the wires reversed in the connector, caused by an updated part that had been installed almost two years prior.
