I've got a 97 DisI manual. 149K The oil pres light comes on when at idle (750rpm or less) when the vehicle is warm. Currently running 10w-40 Mobil high milage oil. I changed the oil and did my best to clean out the oil pan of sludge w/o removing the oil pan(used a plastic stick and flushed about 3L of oil through the engine to try and move the sludge out. Seemed to make a difference - regardless, got lots of crap out. Anywho - light keeps coming on. Is it probable that the oil pres sensor is too sensitive? I certainly don't want to destroy an engine, but also don't want to spend a fortune chasing a non-problem. Any insight?

Hello,
Have you tried an independant oil pressure guage?
Likely the sender has reached its sell by date, it would be good to get an accurate reading though.
A new sender (RNM104) is $25.70 and in stock.Les Parker

Oil Pressure Switch
Do Disco 1's have a 3.9L? If so, check this out:
The oil pressure switch is on the oil pump housing. You do not have to drop the oil pan.Comment
