one way is a sandwich plate at the oil filter..
put your temp sender there.

I had oil press. and temp. gauges in my I4 westy and it was interesting to see the difference in oil temp and water temp, and to monitor pressure (but to be honest, the oil pressure never gave me any worries). it was trivial to install temp and presure sender on the I4, but on the wasserboxer it is more difficult. I need to make an extension to the port between the puhshrod tubes for the pressure sender, but where to install oil temp sender? Is there room at the other stock pressure sender location to install a short T?

Therefore, for the purpose of determining engine health, which I though we were discussing, you must use 3 data points or, again, you're guessing. And if a guess is close enough then you're ok.
