After my recent long trip, I've noticed the oil filler tube on my '90 Westy
is leaking. I know it had a slight crack before, where the crimps are in the
bend, but wasn't leaking. I think what may have started it is, after I got
home there was a really noisy lifter on the right side, so I added 1/2 qt of
Marvel Mystery Oil (it was already 1/2 low). That quieted the lifter and I
then changed the oil and filter, but I think the solvent in the MMO also
cleaned the crud out of the crack in the filler.
Anyway, I can't see how to get at the upper nut where the filler tube is
attached to the crankcase. Any ideas?
Thanks,
Jerry
