If the ID of the hole is ferrous OR non-ferrous I'd hit the mating surface of the seal with a quick shot of 7649 Primer N to activate the surface, then apply a thin bead spread around the metal hole with a Q-Tip any of the thicker viscosity retaining compounds. This should work fine.

Remember, a thinnish bead. We're trying to minimize the squeezeout to the innards of the engine. Don't glob it on-thus the Q-Tip trick to help you better control the amount of retaining compound you apply.

Then gently drive the seal into place and let it sit overnight.

As far as a specific product suggestion in absolutely no order of importance: 620, 609, 680, 603, 660.

Good Question, Great Application! Thanks for asking-this question and answer will get someone out of a jam one of these days.

No, really, the mustache means I love you.
