Try one from a Ford Duratec 2.0 & 2.3 / Mazda MZR I4 (focus, 3, 6, mx5 2006->, escape, tribute, ranger,etc) . They have one mounted in the rocker cover, in oil, with good o-ring sealing to keep oil in engine, and work a treat. They are essentially a conditioned mag sesnor, with digital output, run from 5-12v. Temp range no probs, have had my oil to 145C with sync or sensor failure. Might be able to get you a Ford part number, they are Very common.
else use a mag sensor like on Ford modular V8's post 2002 (Us lineup & aussie falcon V8, I6 uses same style of sensor,m in the oil....no dramas ever...i work in OEM).
Have used these on road & race cars, without EVER having a failure....being auto OEM parts, they meet stringent temp & enviromental durability.
Not taking away from the MoTeC parts, but i find these cheap & simple coz they were actually designed to do the job you asking to do!
