Just to give you some more 03 numbers.. How ever mine is outside the VIN range..

Cold 54/56psi
hot 13-16/43-46psi

I run 5w-40 rotella
89k miles

 

I believe the misalignment issue is all consumed in the housing, tho' the tolerances are close in the gearset, I'll bet the gears are bulletproof.

Your oil pressures are close enough to specs, I don't know that you could improve them w/o considerable time/money.
(remember the rave cd states the pressure relief activates @ 50psi. - If I had numbers above that, I'd calibrate my guage or suspect press relief was stuck)

I like to use other's numbers as guidelines only, I went the extra mile with my numbers by calibrating my "in truck" aftermarket guage (it read 5# low initially) with my mechanical test guage which compared favorably with a couple of other guages I own.
(you're looking for repeatability on readings)

(I used to test flow & pressures for work)

Read up on the "georotor oil pump" that LR went to in the early '90's .

It settled my nerves.

luck,greg

 

Try a different mechanical gauge. Not all read accurately or are calibrated worth a crap. If you get the same numbets with both gauages then you
can believe it. One guage from another could easily be off by a pound or two if not more especially if the guage reads up to 100psi

 

thanks guys. ill get a mechanical one and double check the numbers
