Bob, I can send you the bolt (I have a ton of extras) but being that I have removed quite a few of those, I can say with near absolute certainty that the sealant that holds those plenums on is nearly bulletproof and a leak there would be REALLY wet with oil....not just a bit damp and dirty like yours is. In addition, the bolt hole is a "blind" hole which means that it doesn't go through the casting into a place where it will leak through the bolt hole.
