Like you said Ken they can overheat really fast.  I hit a deer once with 
our CRX near our house.  The guage started to climb within less than a 
minute so I shut it down and coasted, luckily downhill, the rest of the 
way to the house...no harm done (other than the hood).

There is a pressure control device on the oil pump.  It is easily 
accessible from under the car, but it would be strange that it would 
have a problem.  On cars with oil temp guages it is behinde the sender 
on the oil pump on cars without it is behind a large (maybe 19mm) bolt.  
I can't think of it causing problems unless it was clogged up with 
chunks of stuff, then that would be the least of your problems.  Maybe 
others have had other experience.  The valve is really simple.  It is 
just a spring loaded control valve.  You could take it out and clean it 
just to be sure.

Are you sure the leak is recent?  Or are you more sensitive to things 
being amiss now?  Is it actually using oil at a noticable rate?
