Oil pressure

Hello everyone. I have a question. Could someone point me in the direction of where I could find what the oil pressure at idle should be? I have checked the 4th gen service manual, and looked online. No luck. Thanks for the help.

^^

Be sure the oil's warmed up before taking the reading. And it's in section 8 of the shop manual (p 8-8 in the 92 and 93 versions)...the page called "Oil Pressure Testing".

Re: Oil pressure

Depends if it's warm or cold.

Re: Oil pressure

I have already taken the reading. At operating temp at idle it was 10-12 psi, at 3000 rpm is was 60-70. My oil pressure light has been coming on at idle lately. Thought I'd test the pressure to determine if the oil pressure sender was bad or not. I guess it is... As a side note, VTEC has not been engaging properly since this started. Any hints?

Re: Oil pressure

Remove the VTEC solenoid, clean out or replace the screen and replace the gaskets. Easy, quick and the parts are cheap.

Re: Oil pressure

I replaced the VTEC solenoid gasket and screen, distributor oring, and all the valve cover gaskets less than a 1000 miles ago. My thought is that it's a bad oil pressure sending unit considering that the oil pressure reading is within specs.

Re: Oil pressure

I replaced the oil pressure switch. The light still comes on. Any more thoughts?

A short in the circuit that keeps the light on?

Re: Oil pressure

Having done more research, could the oil pump be causing this? I checked the oil pressure with a gauge, replaced the oil pressure switch, and cleaned the IAC valve. (the oil pressure is within spec.)

Re: Oil pressure

If the oil pressure's showing in spec on a reliable gauge, the pump should be working fine.
