Sorry to open this thread again, but we just finished a 2500
km drive around Egypt's  "Desert Oasis Loop" and again we
drove over a lot of sand and through sand storms etc. and my
K&N filter is again very DIRTY.

I took some pictures this time and they are at:
http://www.photopoint.com/ .   Enter my email address (
stebbins@aucegypt.edu ) in the upper right corner of the
page, where it says VISIT ALBUMS  and the album is called
"K&N Filter Pictures", click on the thumbnail size
pictures,   Note that there is an option for each picture
(down at the bottom right) to make the picture FULL SIZE.
If you have the band width, you may want to do this for the
detail.

What I see here is a very dirty air filter, but the inside
of the carb plate is fairly clean.  There is some bits of
sand on the inside on the plates, but not dirty.  The top &
bottom plates over & under the filter are very oily and if
there was as much sand dust getting through the filter, I
would assume that the the inside of the carb would be about
as dirty, or at least show evidence of the sand dust getting
in past the filter to coagulate on the oily parts of the top
and bottom plates.

I should also say that even with the dirty air  filter, the
engine ran fine (we had other problems (coolant pipe burst)
but that's another story (coming soon to a list serve near
you :-))

I look forward to hearing what you guys have to say after
looking at the pictures.  Malcolm
