help please. ihave an 1983 range rover 3.5ltr with an oil prob.
i have 40-60lb pressure but i only have to drive about 3-4 klms to have the temp go to 240-250 deg F.
the water temp only 1/3 up scale. i replaced the gauge and sensor with an aftermarket vdo type but reads exactly the same. has anyone struck this problem before?

 

So are you saying your oil temp is running in the 240 range?
If so, I would look more at the coolant system, it is not the oil's job to disipate the engine temp, that is the coolants job. I would suggest you look and replace the t/stat, if that doesn't settle the heat down then go to a radiator shop and have them check your radiator for blockage, may need to be cleaned out.
