Funny re bugs ... I think.
On the bright side, I have figured out the leak.
Here's what I just sent to my Guzzi gang of Norge owners:
Think I've broken the code.
The weeping leak was NOT from OPS, cam sensor, or crankcase vent.
I pulled the alternator cover. What a monumental PITA, at least with front wheel and forks in place as they were not last time I did this; then again, I am easily awed by such things.
Anyway, lookee at what I found. See pix. Several appear quite similar but give different views in to the hole.
Yup, the hole for the lowest fastener on the RH (as you face it) side is oozing red (Motul) oil. Clean & clear, i.e., not black. Appears to be a very small fissure of pin-hole size.
This is above the sump and subject only to crankcase pressure and splash oil.
So, what is best fix now?
I've talked to some of you this afternoon, and -- while a new "firewall" back there is a theoretical option, I am not going there; intend to use some sort of bonding material, e.g., JB Weld, at the back to try to seal the hole or crack that is letting the oil through. That can be problematic in application or, perhaps more accurately, might be problematic for ME to apply!
OTOH, as Dr. John suggested, maybe just some Permatex or similar bond on threads and at fastener head, perhaps augmented with an o-ring might do the trick.
Oh, causation. I was the last guy to reinstall that alternator cover. Before, however, you declare me guilty -- tho the evidence is awkward for my defense counsel -- consider that I am fastidious about removing fasteners in order and in putting them in plastic trays in order of removal. I have not measured that particular hole (yet) and certainly don't recall feeling that or any fastener bottoming out.
But I cannot say that the very same original fastener that I removed was the same I replaced. They appear to be same size (16mm), but burring on ends are a bit different. You can see the one I removed this time, as it still has a visible coating of oil on its tip. Confusing to me how this happened. I throw myself on the mercy of this court, but you all make Torquemada seem benevolent.
Yes, I also earned a Purple Heart along the way. The lift's brand name is an ironic backdrop to my wound!
