Hey Jim
Steve Devine here.
Just thought id give you a little more info on the car.
I didnt rebuild the 4.0
it was a low milage motor 45k out of a 96 discovery. Oil pressure at idle is
23lbs
when the motor is at higher speeds it run to 50lbs and stops there.
I took a ride up to the local land rover dealer and the mechanics seem to
think this was acceptable.
a lttle high maybe 5lbs.
Thanks for your advice and insight. Im still learning.
