Observed Oil Temp variations:
- At cold startup and idle, oil temps would not exceed 170degF.
- During cruise, oil temps would vary between 150 - 170 depending on ambient temps.
- Upon coming to a stop, temps would increase to ~210+degF.
This was observed with my *external* oil pump / cooler malfunctioning. Since I've capped off the stock oil cooler routing, then my car was essentially operating as a normal 7MGTE would and I'll expect similar temps with a car with existing OE oil cooler setup.
Since then I've completed my oil delivery / cooling mod: External / relocated oil filter + Setrab oil cooler + oil thermostat + accusmump, I've seen temps increase to 170degF at cold startup, hover around 150 - 160 at cruise, and increase to about 165degF at idle after a long drive or any spirited driving.
HTH,
Howard.
