need help with oil pressure

[linbar99]

just bought a 93 integra,that had been sitting for a year. changed the oil ,filter,plugs,air filter,pcv,and the oil light switch. after about 3 min of running the oil light comes back on. previous owner said the light would flicker on occasion. what should i do

Try replacing the oil pressue sensor on back of the motor to see if that helps. It shouldn't be coming on unless your low on oil.

i beleive thats what i replaced,just to the left of the oil filter. and it has fresh oil and filter too.

Hmm well in that case I am out of ideas lol. You could hook an aftermarket oil pressure gauge up and see what kind of pressure your getting. If your getting low pressure then maybe its a bad pump?

it could be a bad pump

I agree with Nerk and Dylan, it could be a bad pump. An aftermarket oil pressure gauge would probably be the best bet here. You can buy a "T" fitting so you can use both your factory sensor and your gauge. They're really easy to install.

Good luck.

thanks ill give that a shot,about what pressure should i be seeing

On cold start up, with an LS, you should see about 90 PSI.

Once warm, it should drop to about 12-15psi at idle. If it falls to ~5psi at idle, you have some problems.

idk if you guys no, but oil pressure really doesnt have much to do with the pump. thats just a deleviry device. the mains are what generate the oil pressure, SO you could need new bottom end bearings
