<VV> Leak at the base of the oil pressure switch

[Frank DuVal]

I've used teflon (PTFE) tape on oil pressure switches for years. I have 
never had one not ground to light the light. Just two wraps of tape is 
what I use.

New switches come with PTFE already on the threads.

Good idea to make sure the lamp lights anyway...

BTW, PTFE and other dope works mostly by lubricating the threads so one 
can tighten it more. The threads are tapered, so tighter (rotationally) 
is tighter (thread gap wise). This explains why never-seized worked for 
one user. Of course the filling of the gap with goo helps also, unless 
the stuff in the pipe eats the goo!

Gasoila is a very good dope for sealing threads on gasoline and engine 
oil tapered pipe fittings. It is NOT for flare or inverted flare 
fittings. Nothing is for those!
