I can  usually perform most any repair on the venerable 1.9 or 2.1 engine.
But  here's one where I've become stumped.  The "high side" oil  pressure
switch located just below the crank pulley and next to the oil  filter mount
has developed a crack in the plastic and is producing a  consistent drip,
thus oiling up the backside of "Ole Putt".  How does  one access this little
jewel and replace it with the engine in the  vehicle?  A 24mm deep socket
would be perfect except the heat shield  prevents the attachment of a ratchet
to unscrew it off (and of course screw  the new one on).  Right now it looks
like the cat and muffler would  have to be removed and the heat shield
removed to get the extra room, but  if anyone else has done this another way,
I'm all ears.

Because the  2.1 is installed in my 84 Westy, there is no "Dynamic Oil
Pressure Buzzer  System", so the switch just acts as a plug.  I would
probably replace  it with an appropriate length 10 x 1.0 threaded bolt sealed
with teflon  tape.

Jim,  you should be able to use your 24mm socket with a ratchet or breaker
bar.   The trick is to bend the muffler heat shield a bit to get the clearance.
 But, I see you have this 2.1 in a '84 unless you installed the heat  shield
from the 2.1 Van.  The heat shields are different so some  modification of
that ' 84's heat shield will be necessary.
