Oil temp sensor

Thanks Brad,

just to be sure: 996 driver's side = 986 passenger side
Do you mean the spot where the oil pressure switch goes? hmmmm that's where I have already my oil pressure sensor to feed my oil pressure gauge.
If that's the case then I'd need a T adapter to connect both the oil pressure sensor and the oil temp sensor ?

Correct on the tee adapter, which is what my friends made for 9X6 engines.

Yes, the pic above is the oil pressure switch on an 01S

Hmmm how are the temperature readings here? What do use for sealing the M14 threads? Seal ring?
Are there better fittings with an o-ring??

You could get rid of the idiot light probe and put a temp probe in there but are we going to get hot temperature here? There is another unused plug in the left bank for the 996.

If you guys have accusumps in you could probe it at the sandwich plate area...this may be hotter

I believe the oil level sender in the 987 is effectively a dual element unit that also includes a temperature sensor as well. The sensor isnt wired up on the 987 to display though , it goes back into the rear DME. Its possible the position of the oil level sensor in the 987 may be a blanked position in the 986 and the 987 dual element sensor could be retro fitted ? Since the 987 and 997 and likely 996/986 share much of the same engine components Id suggest that looking at the part and location of the temp sensor in the 996 may be a good starting point. Its possible the 986 shares the same part as the 996 which may also be a dual element unit though not wired on the 986.

I definitely remember seeing a temperature sensor on a M96 schematic...I was afraid of splicing into it's lead of course so didn't consider any further but perhaps it would be no problem as long you could match its output with a gauge

I believe the output went the DME
