N62 4.8 Oil Thermostat Gasket Leak (2007 X5)

[snik]

The 4.8 seems to run cooler than my E46 M3. If I'm to just go off the oil temp needle.
Which kind of surprised me considering it's a large V8.

E70 doesn't have an oil temp needle? Also it's beyond me how a 105 degree thermostat on the 4.8 runs cooler than an S54 with a 80 degree thermostat. I'd be interested in actual numbers read over OBD port.

The 4.8iS has a oil temp gauge. Same range as the E46 M3 and it consistently sits lower and rises slower.
Didn't think about the coolant temp tho.

Has anyone done this job on a E53 4.8 with the oil cooler.

Mine has a very very slow leak (not losing any measurable amount of oil, just some drops) but I want to tackle this before the gasket let’s go on the way back home after I’ve been snowboarding all day.

This is a right hand drive vehicle without “servotronic” steering and it doesn’t have the fancy water cooled alternator neither.
