Subject: RE: Oil leak on right cylinder

Hi Charlie,

My little sheet doesn't list a torque spec for this. Neither could I
find one in Guzziology or the Chilton book. I jumped over to the Moto
Guzzi Shop
(http://www.motoguzzishop.com/Big_Daddy/Big_Daddys_Workshop.htm) and
found that Big Daddy recommends no more than 15 foot pounds. That seems
more reasonable to me, especially because this is just a "sealing"
location.

AJ, you might just want to get a new washer. I think steel washers were
originally used??? But I don't see anything wrong with using an aluminum
crush washer in this spot. Anyone else care to chime in?

I'm with Matt on this one. If the plug over the top (12 o'clock
position) nut (the one that you tightened with the 10mm allen wrench)
isn't tight or the crush washer doesn't seal well, oil will run down a
"tunnel" cast into the head and drip out just where you describe. With
the tank in place it's kind of hard to get a good look at it, you could
probably hold a mirror between the tank and cylinder head to look down
on/into it. Or just pull the valve cover and use a little sealer (such
as Permatex 300) on the crush washer and plug threads then reinstall
snugly (there's probably a torque figure on Greg's site). Clean the
threads thoroughly before using the sealer. Cheers,

Just went and investigated a little more. Got some Dawn, a toothbrush
and a rag to do a little cleaning. The leak is above the head gasket by
about two fins. Not from the back side, only in the front (away from the

bike). While it runs along the entire front half, intake to exhaust, it
seems to be concentrated in the middle at the six o'clock position. This

is where the head bolt is below the spark plug. My best guess is this is

the source of my leak.

I used a torque wrench, should I snug it up some more?
