I think I'm using the correct terminology. On my 996 I posted here before how I had thought the little plug bolt underneath the mesh filter looked like it had been slightly leaking some time ago. Anyway at that time I decided to reseat/retighten it even though I had never messed with it. Anyway I couldn't find the torque value and so ended up overtorquing. My guess is I torqued to 25nm but later found in the book that that little plugs torque it like 9nm. Anyway I could tell I had overtightened as the little aluminum washer got crushed.
To get to the point today I decided to drain the oil and put on a new washer. But I think I can see that one of the thread furthest away, at the end of where the bolt would be, is not there. I'm guessing I messed it up.
Should I just use the sealant on the thread that you're supposed to use according to the boo, put on a new washer and hope it doesn't leak. Or do I need to learn how to retap. And how do I do that?
