my oil engine light came out whethever i puss the gas a little bit .... when im on gear and running, and goes away the second i leave the gas completly
if i put just a bit when accelerating , it will do it but sometimes flash.

i dont lose and burn any oil
my dipstick have correct oil in it,
i did change oil and did put the excxat amount on it,
so it dont need more oil

why my oil light came out , ?

Low oil pressure?

maybe your oil pump is on its way out? Perhaps your oil pressure sending unit is shot? It's time to run a manual gauge. Just 'T' it right at the electronic sending unit. It's cheap and works great!

thanks i will try that,
if i didnt ask too much power, the light stay off
i hope its only dirt out there

You should be running a oil pressure gauge, because low oil pressure will ruin a turbo real quick.

i have unbolt the bolt next to the original oil pressure gauge and bolt my gauge line in there,

but there is no oil there, and there was no oil there, the back of the little hilinky bolt is black dry ,

should i took off the original sensor and T it there ? or is not normaL i dont have oil coming in the gauge tube from where i have T it

no oil goes tru the tube i tee in the engine...
side of the original oil pressure sensor,
the back of the bolt there waS DRY black,
should be have some oil there ??

i start the engine but no oil came out, so , gauge stay at 0

any input?

i would use the same port as the stock pressure switch..

but it seems you may have lost an oil pump

its look that way, oil pump fail, im not sure but,
how the hell the oil pump is out of service after 105 000km... ?
ill keep it update

DEATHs OEM oil pump (rather the oil pump pulley) failed at ~60000kms

i have succesfully install the oil plug into the original oil pressure oil,
pressure is 60 at start
when hot 20 at iddle, and soon i
press the gas oil pressure goes back to 60

someone know what it mean ?

Oil is cold at start up and so its thick causing higher pressure, after it warms up it thins out causing lower pressure. then when you increase the RPMs ith oil pressure increases as it should.

loooks like toyota wants >5psi at idle and 36-71 at 3000 or so, your good.

so that sender is bad, OR wiring is loose

after installing the gauge, its seem its all good, but the oil light open sometimes when i speed up, even if i had disconnect it lol, it was obviously a electric problem, maybe my engine move too much backward on its mount when accelerating making the wiring harness to move a lot... i think

That sounds good, mine is at about 70 at start up and then once warmed fully, it will idle at 20. If I get the rpms up to about 3100, it peak at 60. I think your pressure is perfect.

Low pressure = high flow = oil is hot and thin. OR low. Keep that in mind. My pressure on a cold start will usually rise to about 40 and then start dropping if I'm low on oil.

High pressure = low flow = oil is cold and thick.

Think of pressure like the difference between drinking a Coke through a straw, and then drinking pancake syrup with the same straw. Thicker stuff requires more pressure to move.

Those pics don't look like the 7AFE, which is what I have. Cold start in hot weather gets me 60 psi, cold weather 65-70 psi and takes forever to reach that. Idle pressure at operating temp is 15-20 psi. Cruising pressure at 3,000 RPM at operating temp is around 35 psi. It usually drops a few psi with the A/C running. I assume this has something to do with changes in vacuum/PCV system when the A/C is on. From what I've read, and this is just a "universal" standard, is you want 10 psi for every 1,000 rpms the engine is turning. Obviously though, at operating temp you won't see that. I only hit around 40-45 psi at 6,000 RPM at operating temp.

So your pressure sounds fine

in fact , i worked all day whit my car , (3sgte 3th gen) delivery and i keep it running for 8 hour stopping it and starting it again and again,
i did get 9-13 psi at iddle at 100 degree water temp, and 65 psi when accelerating
20 to 40 psi according to less accelerating
