Oil filter adaptor for screw on
filter for Mkl-lll cars.
By Karl Schluter -Low Zep
(While
I can't or don't wish to own the rights to the plans I have put here, I would
like to think if someone uses my plans to make and sell these, that they
would consider Car clubs and our web sites first before on line auctions)
Below
are the plans I have drawn up for two different designs of adaptors. Design the
screw on fitting to take a filter with an anti drain back valve installed
inside it. Work in a filter that is common in your country and that will be
cheap and available for a long time. The adaptors are to be sealed to the
engine block with the factory or a replacement O-ring installed in the factory
canister block groove.
The
adaptors would probably be easiest made out of alloy block and both types have
4 or more holes spaced (shown on the plans as oval or round black holes) placed
evenly between the centre adaptor hole and the outside diameter to let oil flow
from the filter through to the block. These should be drilled roughly in line
with the chosen filters drain holes, although this differs from filter to
filter, it is not too critical. Oval or simply round holes will suffice.
These
plans are a guide only and the thicker alloy adaptor could even be plumbed for
a oil cooler installation or an oil accumulator for pre start up oiling etc.
Engineering and plumbing supplies have hex nipple adaptors of various types
plus one or more could be made from scratch. The alloy block that has the two
adaptors screwed in each side could have one large long tube adaptor screwed
right through the body of the alloy block instead.
If
the adaptors, or hex nipples, are to be sealed in place, use sealant or
loc-tite sparingly.

are some pictures of an adaptor Simon (Rutesixtysix0) sent in of an adaptor he
had made up. Note, it is all one piece. Thanks Simon!

How to hide your screw on filter
and adaptor.
By Karl Schluter.
Some
car owners are reluctant to go to the screw on filters, however, unless you
have an unlimited supply in your garage, its time to face the facts that at
this time they are not being made anymore. Here is an idea I have thought up
that may help hide the above adaptor etc. Screw on filters are available in a
lot of different sizes from large, short, fat and skinny. The below picture
shows a smaller screw on filter being used and the alloy adaptor with its outer
perimeter turned down to allow the factory oil filter cover to go over the outside
of the whole spin on filter and adaptor. The factory Z-car cover does not go
into the block anymore but comes up to the original diameter of the adaptor,
which should be left proud of the block by 10 -20mm.
Remember
too if you cannot find a short filter, an factory outside cover could be
extended as only a part of it is viewed in some of our engine bays, eg: Mkllls.
Have the center bolt nut cut off the original center bolt and affix it to the
outside canister center by brazing etc remember, its only there for looks. The
outer can should be a slide on or slight press on fit to the outer shell of the
adaptor, it does not go into the block anymore. The adaptor should
be drilled and tapped carefully (avoid the oil ways) to allow a locating
stud to be loctited into the underneath where it is hidden as in the picture
below.
I
hope this helps those wanting to keep their cars looking standard. Karl.
