I just installed a 4.0 into a '03 Disco 2 after my 4.6 died.
I have a mechanical oil pressure gauge hooked up to a fitting between the block and the oil filter that indicates I have around 50 PSI at idle and it goes up and down with RPM from there.
However, my oil pressure light is on most of the time. It goes off after about 30 seconds of run time, stays out for a while, then comes back on, goes out, flickers, just doesn't seem to consistently stay on or off...
Vehicle seems to run fine otherwise.
Any ideas?
