b16 low oil pressure when it car gets warm
 

i got a b16 block wit gsr head when my car is cold the oilpressure stay at 40 psi but i as soon as it get warm the oil pressure drop to 20psi and sometimes lower i need help please why does it do this

help me please

could be sensor or oil pump go take it to a shop

which sensor

umm not sure...i just got into honda..my camaro z28 did that and what the sensor..

thanks can anybody help me

20 psi at idle when the car is warm is perfectly fine. Oil pressure will always be higher at idle on a cold engine because the oil is thicker when cold. As long as the pressure goes up with rpms you should are dine. You should be putting out around 60-80 psi by 2000 rpms and above.

My car idles around 20-25 psi when warm

:thumbup:he knows and is correct

if you're not reading normal oil pressure during the higher RPM range
you should do a cylinder compression check... might need new rings

thanks

It has nothing to do with rings or ring wear.
Low on oil
Clogged oil pump pickup
Worn oil pump
Bad oil pressure sensor (oem unit on block just to the left of oil filter)
Bad oil pressure gauge, sticky needle (if not an electronic unit, could be oil feed tube leaking, or kinked)

ya i kinda had same problem everyonce in a while the oil light would start blinking....it was doing it every 20 miles....i changed the oil and it came on couple time but it stpped and the car runs fine so i figured that the screen in the pick up tube was cloged and new oil fixed the problem.
