Weeping over Seeping: Chasing Leaks on the EV [with Bonus Mystery Houseguest]

(1/5) > >>

Bill Hagan:
So, yesterday, I dropped by Winchester Motosports, where travman tried to get me to stray from Moto Guzzi. 





Gotta say that for ⅔ (if not better) than the price for that 2016 (or whenever) V7 I’ve been musing on of late, that Royal Enfield is very tempting.  Seriously, would be a great day tripper on some of the local tight roads that have virtually no traffic, and on which the Norge, EV, and Griso just seem over-large.  We shall see; sure do like that yellow.

Ah, but when I got home to my Moto Grappa harem, and while waiting for some supplies to get here on Monday, I went back to puzzling over a leak on the EV.  No, not that oil-temp sensor on the left valve cover.  Think I’ve finally beaten that into submission.  Yes, I know.  Please don’t say it. 

No, I’ve been chasing this leak for sometime, but I wonder if I’ve finally stumbled on its possible source.

Please take a look at these three pix.  Essentially show the same thing, but the lighting, etc., makes it show up a bit differently in each, so here they are.  I cannot figure out how to put little arrows, etc., into photos, so just look for that plug between (and a bit below) the dipstick and that fastener for the starter.









What is that plug?  Seems blocked by the frame rail.  If an actual access plug into the lump's oil supply, size?  I don’t have any wrenches thin enough to et in there to even figure out the size, much less get a grip and see if I can tighten it.

OBTW, as long as I’m posting some pix, see what else happened today.

First, this questionable car pulled up in front of the house.






Well, look here; it’s Lannis, on his way to the swap meet at York, and stopping in for a free lunch.  Yes, we still have Christmas decorations up.  Long story.







FWIW, Lannis was a great guest, tho about as useless as I am on ID’ing that plug.  He did offer to show me how to use some special Moto Guzzi tools.







So, I am still left with the problem of the incontinent EV and wondering if that plug is the culprit.  Any help out there?

Grazie.

Bill

Buy a set of really cheap wrenches and grind them down until one will fit . Probably somewhere between 11 and 13 MM ... maybe . Oh , and  keep Lannis away from the bike  ;D

Muzz:
I did a deep thocus on this problem Bill and have come to the conclusion I have absolutely NO idea as to what the plug is.

However, I do see a 2nd hand Breva in your life rather than an Enfield..... ;) ;D

Dick:
The plug is a magnet. Picks up starter/ring gear metal shavings.

PS: Magnet is in a dry environment,(no oil,or shouldn't be).

Vasco DG:
The plug is a magnetic one I believe. '98 Cali uses P8 'pooter and i think has two crank position sensors. One in the 'Conventional' place on the timing chest triggered by the phonic wheel on the nose of the cam and the other triggered off the flywheel at about ten o'clock on the bell housing part of the crankcase, (When viewed from the rear.) the magnetic plug is diagonally opposit it and is there to catch crap that gets knocked off the ring gear during starting. Thing is it's supposed to be 'Dry'.........

Pete

PS. Thinking get about it the Cali may not have the second trigger, I may of confused it with another model, but that is definitely the magnetic plug perhaps a hangover from a previous model.
