<p class="MsoNormal">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 higher quality, although I guess I shouldn’t complain about 20 years of service.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I suspect the one I just put back in is the original sensor and survived the 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. Then I figured I could just carry a small bolt with a copper washer. Given the 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. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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?<o:p></o:p></p>
