Low Oil Pressure

91lxhatch · July 28th, 2007, 09:38 PM

I have a 91 LX 5.0 and yesterday i was stopped at a light and realized that the oil pressure was reading low. So I checked the oil and the oil was fine. It seems to happen after the engine warms up but fine while driving. I don't know if I should bring it to the dealer or if it's just a gauge failing after 16 years. The motor has the original motor in it with 66,000 miles on it. Any help would be appreciated. Thanks.

Check the gauge, and sending unit. Hopefully it isnt the oil pump.

before worrying about anything, get a mechanical gauge and check the oil pressure. It is normal for the pressure to drop at idle when warm.
