Hi Dave --
Well, it may simply be the wrong type of filter for the car. Are the
threads in the filter recessed? My Spit filter has the threads up
very close to the gasket surface.
For late Spits like ours, I believe there were two kinds of filters
used, depending on which thread adapter you had. The two were AC
PF13 and AC PF53 (or obviously any of a number of other brands; you
can look them up in a cross-reference catalog at any auto store).
I'm curious what you mean by "threaded pipe". My Spit has an adapter
that you thread into the engine block; there's a hex portion in the
middle that allows you to tighten/loosen it, and then a threaded
portion (different threads than what goes into the block) which mates
with the oil filter. Does this sound like what your friend has?
Hope this helps.
Dan
