Ok, I'll take a stab at this one...

I'm guessing that you've got a clogged oil gallery somewhere in the
block.  This is preventing oil from getting to the proper places and
thus it must find somewhere else to go.  (Out of the engine)  Perhaps
you could get some of this engine clean stuff for the oil, run that,
drain it and see if it gets better.  (I've never had luck with oil
additives/cleaners, but it might be easier than a rebuild in this
case...)

Nope, but now you know that it's something else.

This is another clue that the oil gallery could be clogged.  Maybe try
attaching the oil pressure gauge on a different spot on the the block.
(This is possible on a TR6, not sure about your Spit)

White smoke (from the exhaust anyway) is a sign of antifreeze getting
into the combustion chamber.  This could be due to a bad head gasket
or a cracked head.  If it's coming from the the valve cover, then
it's hard to say, but since you have a later Spit, it's possible that
a a little bit of smoke is a normal part of the emissions set up.  The
other possibility is blow-by, which can be caused by rings not seated. 

Those are the only things I can think of without seeing the car.
Let us know what you find!
