When I bought the car (1972 TR6) in 2001, a friend suggested that I replace=
 the oil pressure warning sensor in the block.  It just failed at the joint=
 between the metal and the plastic.  Fortunately, being a pack rat, I still=
 have the original sensor which I put back in.  it looks to be of much high=
er quality, although I guess I shouldn't complain about 20 years of service=
.

I suspect the one I just put back in is the original sensor and survived th=
e first 30 years without trouble.  I thought about carrying a spare - this =
failure would have been catastrophic as quite a bit of oil was leaking out,=
 not to mention the mess it made of the exhaust and the undercarriage.  The=
n I figured I could just carry a small bolt with a copper washer.  Given th=
e car has an oil pressure gage which I think would flag this disaster much =
sooner, plus the copious amount of oil underneath would have alerted me, as=
 it did this time.

Does anyone know how far into the block this hole goes?  What is down there=
 and how short a bolt do I have to use?
