Oh, good. Someone else did that a few years ago.I think there is some confusion. I did not apply any on the mating surfaces.
I damaged one of mine last year and attached the replacement without adhesive. The rib on the cover side of the gasket and the little rubber protrusions should hold it in place unassisted. Time and heat cycles will make it stick.I only applied a small dab here and there on the backside of the gasket to fix the gasket in place. Honda obviously did this from the factory with some sort of adhesive glue, not a gasket sealant.
It's hard to say without looking at it, but depending on what you added, where you added it and how long it had to set before the cover was bolted on, it may deform the gasket enough to let oil seep through. It's a lot thinner at temperature, and it doesn't take much of a gap.
