Is anyone able to confirm their warm idle oil pressure on their 1jzgte?
The the mkviv manual says that the 2jzgte should be above 7.1psi at idle, which on a standard car with stock idle would be 700rpm...equates to the good old rule, 10psi per 1000rpm. Im guessing the 1jzgte would be similar to the 2jz?
Anyways, before oil and filter change i was getting around 22psi of oil pressure at warm idle using penrite running in oil 15w40 and a trd oil filter. Completely new engine with 500kms on the clock, did oil change to penrite semi synthetic 10w40 and stock genuine Toyota oil filter and low and behold warm idle oil pressure dropped to 7psi...tried putting the trd filter back on with the semi synthetic 10w40...and oil pressure went back up to 22psi...
Shows how much a damn oil filter can restrict flow and lead to an increase in oil pressure.
Wanting to know what others are getting as a reference...
