The oil light on my 93 Camry recently started to flicker when the engine gets to about 2k rpm. Mechanic says it is either the oil pump or a clogged engine galley. Oil pressure is fine at idle but drops real low at 2-2.5k rpm. No noise from engine/mechanic says engine is still okay. I basically just want to sell the car but don't want to pay a lot of $ to fix the oil pump if I'm not 100% confident that's the problem. I got some flushing oil to clean the engine to try to see if it could be the galley line, but I'm wondering if that doesn't change the situation if it's worth doing the repair to the oil pump (around $700 to do that and replace water pump at the same time) if I just want to sell the car. My basic concern is, what are the odds the problem isn't in fact the oil pump?

Re: Oil pump flickering on 93 Camry
Acheep way to find out is had some power punch to the oil buy a quart for 6 bucks drain a quart of oil and put it in it the light does not xome on then it's fixed. if it still comes on check the pressuere sending unit it could be defective to.

Yes, the oil is the life line to the engine, without proper pressure or circulation the engine will die, no different than us humans. The reason why the light goes off is that the engine is running at higher RPM pushing more pressure to the sensor therefore it turn off the light. When the engine running at low RPM the oil pressure is low therefore it not enough pressure to turn off the switch. 1st. it cheap, replace the oil pressure switch and make sure the oil dip stick at proper level. If replacing oil pressure switch does not rectified the issue, the oil pump might be going bad and not pumping proper pressure. Replacing oil pump is a major job. remember, on any vehicle, if it run proper there should be no lights on and that is the reason why they put the lights there for a reason. Check and see you have a small oil leaks.
a loose connection WILL NOT cause flickering oil light unless your your oil is empty at the same time a connector is loose. This flickering is most likely caused by clogged oil ports or failing oil pump. When this happens there is insufficient oil running through the engine, causing the sensor to activate the light intermittedly. Have this checked immediately to prevent extensive engine damage. Hopefully this helps!!
as for the 93 model i would say if the oil pump isn't working properly chances are that the crank and con rod bearings will be damaged and possibly piston i'm not sure about repairers where you are but if i were to pay $1200 i would expect the motor to be rebuilt too if it has done some serious damage i woul suggest a reconditioned engine you should be able to pick one up for around $1500-$2000 and most of them come with 2 yr warranty firstly id check the oil filter and see wether there are any debris in it such as metal or brass filings as for the 98 model with oil pressure light flickering on and bad engine knock i would think it was either a small end bearing or a big end bearing probably best not to drive it to long with a bad knock because a worn out big end bearing can end up letting the con rod come loose and break or bend causing serious damage ask your mechanic to check the engine oil pressure with a guage and put a new oil filter on it (Could be blocked)
Sounds like there is an oil pressure problem. Now this can be due to several factors. 1. low oil level in car
2. bad oil pump
3.bad oil pressure switch /sending unit
4. last but not least check oil filter and make sure its not clogged.
worn engine main/connecting rod bearings.
have pressure checked with a manual guage at oil pressure switch for the correct pressure. If that's good then the switch is bad and problem solved.
if it low then you will have to check pump and bearings. Contact if you need more help and thanks for using FIX YA
I HAD SAME PROBLEM SOLVER OF MY MOMS 1996 CAMRY ABOUT HORN GOING OFF AND CAR WOULDN'T CRANK. JUMPED IT OFF AFTER A FEWW FRANTIC MOMENTS OF HORN HONKING-- FOUND OU IT WAS AN ALARM THING AND YOU CAN SHUT IT OFF BY TURNING IGNITION KEY TO ON POSITION AND MOVING TOGGLE SWITCH AT DRIVER KICK PANEL TO OVERIDE THE HONKING HORN PROBLEM--STILL NOT SURE WHAT CAUSED IT TO DO THIS AT BEGINNING. BATTERY WAS FULLY CHARGED AND HEADLIGHTS REAL BRIGHT TOO. COULD HAVE BEEN A DOORLOCK MANUAL MALFUNCTION--BEEN OK FOR A WEEK NOW.
