[s-cars] Oil Leak - Driver's Side of Engine

[Tom Green]

This is a common failure, Tom, and in some cases, the center will blow  
out of
the sensor creating a big leak.  If it was easy to find, I would not  
delay on the
repair.  If you get a big leak on the road, the only thing to aid in  
averting disaster
is that pressure switch indicating you are out of oil pressure (and  
oil)--if it works.

Dave indicates they are cheap, so buy two and have a spare handy.
