Second,  there is a small sensor that appears to be installed in a

oil

passage on the plugs side of the engine.  Its toward the back and

can be

seen

in the same pic with the sensor described in the paragraph above.  I

think it

is an oil temp sensor but still not sure.  It appears that this is

the

usual

location of a oil pressure sensor on a 13B but I'm pretty sure that

this

in

not a pressure sensor.  Again, any ideas would be helpful.  I have

not

yet

been able to identify a sensor that looks like an oil pressure

sensor.

My 1990 13B has a sensor that looks just like it, in the same position,

it provides water temp signal for the dashboard of the vehicle.

Really? That is interesting. Is it a turbo? This is definitely a knock
sensor. The screw hole that mounts this on all late rotor housings
does not go through to the water jacket.

Paul, look at the iron housing next back, under the oil pressure sender
boss. This is what we are referring to, that is a temp sender. The threaded
hole above the trailing plugs is indeed for the knock sensor.

Right you are.
