Brian, you need no guidance on how to extract maximum miles from an engine and
your procedures are proven by your engine condition, the low rev start is
something I will be doing from now on. You do seem to travel long distances and
this will help your oil condition, 4000Km here would start in the North Sea
and end in France via the English Channel.
Spin on filters and conventional filters have one common denominator, the
filter paper. Now whether the same grade is used by the different manufacturers
is a question not easily answered. I will be making a few phonecalls to see if
I can get some answers on this because Rimmer supply a shorter filter
cartridge than does Chris Witor according to Jonmac's e-mail. You can get the
same flow through a small "filter" as you can through a large one if the holes
in the paper are big enough, but it is what passes through the hole which does
the damage. There is absolutely nothing wrong with the conventional
filter as a filter (it's usually cheaper anyway) but it does have the annoying
habit of slowly emptying into the sump and this is why the conversion took off.
I think most members of the group use the Triumph for "special occasion"
motoring so a lot of them spend more time dormant than is the case with an
everyday car and this is the appeal of the conversion. You on the other hand
use your "hackmobile" (Really, Brian, it deserves a better name than that at
it's coming of age party) daily with long runs which help clear water from your
oil, something which doesn't happen with occasional use.
Long may your car continue. Should we refer to you as theWizard of Oz for
keeping a '78 engine going so long
