Default Washed engine, had oil pressure light kind'a on...

I washed engine today, sprayed with degreaser, waited, rinsed off...
Started engine, and had oil pressure light on, but very dimmed. I let engine idle for few minutes, and then drove it for few miles to dry everything off.
Light went completely off after maybe 4 miles...

I think it was just water messing electrical connection on sensor.

Did it happen to anybody?

By the way: how is oil pump driven in 2.0 subaru?

timing belt/crankshaft. there is a sprocket on the crank in front of the timing belt that comes off the crankshaft.


bad news could be in your future if that light came on for the right reason. I think it comes on when it detects 2psi, which is not enough for your bearings to survive long.

Cool, so there's no freaking way the belt has slipped, and oil pump was not working efficiently. cause if so, my valves would be already kissing pistons.

I'm sure it was some moisture caused short/electrical issue.

Happend to me once after washing the engine bay, about 40k ago. Surprised me to, the light was very dim and went away after awhile. I sprayed/washed my bay at least 10 times to date. I wouldn't sweat it.

The light is an LED and does not require much current to illuminate visibly. If enough conductive liquid gets on the sensor connections this can happen.

^^^

This guy knows what he is talking about....

The sender for the oil pressure light is under the alternator on its left side. Take a flash light and look at it. Its a normally closed switch that opens on +/- >5psi. So disconnecting the wire from the sender will turn the light off permanently, touching it too the block (ground) will turn the light on...

I think you fine, just watch your oil level to be safe....

Happens to me from time to time. Not a big deal as my engine has 140k on it now.

If you ask me using degreeser is a better option than a pressure washer. Blasting your engine bay w/ a pressure washer can drive water into places it shouldnt be. Getting it wet is no problem. I use degresser and a hose on a low to medium setting.

That's what I did, except not high pressure wash... I used king of "idle" of pressure washer. It was strong enough to do the job.
