I have a 2004 Toyota highlander leaking oil, oil light comes on. Could it be the rubber rings?

a 2004 toyota highlander V6

this should be your engine type
The 2GR-FE is a 3.5 L (3456 cc)

if leaks are that bad
always check the engine oil level before you drive off

fixing oil leaks on motors
degrease whole motor top and bottom

start with replacing the oil sender it may be the cause of the oil light coming on
after degrease
lay cardboard or paper under the car
take out for a drive and park over the paper over night

this pin points most of the oil leak locations
leaks from a V6 motor
rocker covers/ spark plug tube 0 rings.engine seals
cam seals
front and rear engine seals leak often
sump gasket can leak

if oil consumption or light on continues
can be a failing engine oil pump
or worn main bearings giving low oil pressure to the whole engine
you could be burning oil from worn piston rings
or hardened valve stems

a mechanic can fit an oil pressure gauge to the motor when hot
to check running oil pressure to confirm low oil pressure

if engine is worn out

it is possible to fit a lower mileage used motor to your highlander
its often cheaper than and engine rebuild

Oil pressure light comes on at stops in gear when engine is warm. Light goes off in nuetral & park

Hi Cindy:
Make, model, and year would help, also kms.
I'm guessing an older vehicle with high mileage.
You could go try a heavier weight oil, like 15 w-40, or an additive like STP.
If it's not using a lot of oil between changes, it's probably old and tired.............. Sort of like me.

I have a 01 Mazda Tribute,At low RPM my oil light comes on, I added honey and the light didnt come on for a day. Now its coming on. What should my next step be? Oil Pump? Sensor? Or oil change wth thi

Well it could be a faulty sending switch, or the pressure really could be low. A mechanic would use a mechanical gauge to verify the problem.
If it is low oil pressure, you may need another engine.

Oil light comes on, but there is enough oil in the car.

Either the oil pressure switch is bad (or its wiring are somehow shorting), or the oil pressure is low. For the later, it could be having an oil pump going bad or a clogged screen at its intake. I wouldn't drive the car until the problem is solved.

Why does my oil light come on sitting at a red light or stop sign. But when I start driving it turns off?

Oil pressure is always lower at idle speed.I'm guessing you have high mileage.If your oil light is not coming on in drive at idle with the engine cold,but it does when hot,your bearing clearances are probably getting a little loose.Try using one quart of Lucas oil additive in place of a quart of oil at your next change(or just change it now).This stuff is thick and stringy,it helps the oil cling to surfaces.(if there is no change after this,you could try a new oil pressure switch-it's cheap enough.I actually had the switch on my 95 dakota leaking a LOT of oil at high pressure/RPM,which affected the reading).

My 2004 Pacifica wont start at all, the gear is in park but the gears on my dash panel are all lit up, no matter what gear I put it in. I changed the Transmission Solenoid cause their was a hole in it...

What Transmission Solenoid did you replace ? Pressure control solenoid ? Shift control ? P0522 code is not saying oil pressure is low , It's saying the PCM is seeing sensor pressure low ! Do you know how to test automotive electrical circuits with a volt meter ? An this has nothing to do with your gears lit up . Different problem .

Oil light comes on and off when in park idling. oil level is fine.

Sounds like a weak oil pump at higher rpm the pump creates more pressure which is adaquate to make the light go out and supply oil to the engine. At lower rpm your oil pump is not creating the pressure needed. Be carefull not to let it idle or sit in park to long this could damage the engine. There is oil pressure sending unit also this is what makes the light come on and it also shows the oil pressure on the oil gage on dash if your vehicle is equipped with gage. The sending unit could be faulty, but play it safe and have your mechanic diagnose the problem.

Oil pressure light comes on when car is hot

if you have alot of mile son this car its worn crankshaft bearings. Try some oil additive this will help keep the viscosity of the oil up. if you have alot of miles drain a quart and add a quart

Engine Transmission Light coming on intermittently

low pressure in the tranny, did you check the oil level in park? if so you might have to check it in gear with someone holding it on the brakes, then re-check... hopefully it isn;t the pressure solenoid.... $$$$$$.... they can be expensive, cheers!

Oil light comes on at certain times

First, check the oil level on the dipstick. If it is low, add the required amount of approved motor oil. If the level is correct and the light still comes on, there may be other issues.
