Could be the vavle(s) on that specific cylinder. But the best way to find out for sure is to pull off the head and inspect everything visually.
Good Luck!

Don't pull the head to check, it's stupid right now.
Test leakdown again. Pull the oil dipstick, take the radiator cap off.
Have a buddy listen to your tailpipe, a buddy crank the car, and you and another buddy listen to the oil dipstick, throttle body, and watch the coolant.
If you hear it out your exhaust, it's the exhaust valve. Throttle body, it's intake valve. Oil dipstick, it's rings, and coolant, blown headgasket/cracked head/block.
Hear/see nothing, then pull the head.
