whats it supposed to be at?
cold?
idle?
throttle?

also - could low oil pressure cause a "slacking" chain tensioner? (the tensioner is brand new, but then again, so is the oil pump)

i did some searching, but i got a wide range of answers from 15 psi to 120 psi, so i thought i'd make a new post

thx ppl.

I get at cold idle about 75psi on start up. Once nice and warm in the morning it will run about 30-35psi. If it has been hot out, and I have been driving it hard it will go down to 15-18psi (this is like 90+ out side). normally under WOT right about 50psi, dependiong on outside temp.

not sure if this will help but ... 2.4 specs clicky

my oil pressure on 2 different 2.4 with different milage was 10-20 idle hot , 50-60 hot driving

cold any were from 50-100 psi
