if there is a metal sealing ring between the oil pressure switch and the
engine block ........
it could be leaking there, and tightening the op switch or putting in a new
sealing metal ring, if it uses that system, might help.
Hi mark 91 westy,
Sometimes it's hard to tell where they are actually leaking from.....
whether from the wire connection area, the 'top' of the op switch, or from
where it screws into the engine.
try spraying white talcum or baby powder onto the area, and see if that
makes 'the' leak stand out.
oil pressure switches can leak, but I can't think of the last one I replace
for that reason, fwiw.
some oil pressure switches are tapered at the threads, and don't use a
sealing washer.
some are not tapered, and do use a sealing washer.
be sure of which kind you are working on.
if it's an aftermarket american one or something ..........I wouldn't want
it on my vanagon, that's for sure.
Scott
