Evening all,
Long time no speak. Some of you might remember me trying to solve the riddle of the source of a slight oil leak which showed as vertical dribbles on the inboard wall of the primary chaincase (1965 B40F.) I'm wondering if I MIGHT have solved it by a very simple thing: a new fibre washer and a good dob of sealant on the chain oiler screw. The oiler element of the screw had already been closed off, but maybe the oil was getting along the screwthreads and out onto the inboard face of the casing? Why the dribble marks would be forward of the oiler and yet still vertical, I don't know. But after I put on another new fibre washer and (I think this is the important bit) a good dob of sealant, I went for a ride and on my return saw no dribbles. Early days, further checks needed, but fingers crossed. Any thoughts please about whether a leak at the chaincase oiler screw could result in dribble marks where they are(see photo)?
