Stuck compression/leakdown adapter? Here's what worked for me!
I recently got my leakdown tester adapter stuck in my spark plug hole when it disconnected from the tester as I was unscrewing it. I read people putting loctite on the hose threads, needle nose pliers, hammering screwdrivers, pulling the head, etc.
But I found something simple and easy: a new o- ring!
Put a new o-ring on the tester hose, and do not use any oil. Now screw that sucker into the stuck adapter and they should screw right back out!
My theory is that a new dry o-ring has more rotational grip than an old oily one, so that keeps the tester from detaching from the adapter.
I've seen this is a pretty common problem, and it worked for me so I figured I'd share. Good luck!
