Default 95 legacy 2.2 low oil pressure

SO i have a 95 legacy with a EJ22 yesterday driving i saw the low oil pressure light flicker at idle after it warmed up.

I kept an eye on and it babied it home, Today i replaced the Oil pressure sending switch hoping it was a failed switch.

So I let the engine warm up and pretty much the second it hit operating temp the low oil light began to flicker.

At normal throttle its maintaining oil pressure just fine.
only at around 750-800 RPMS it goes on.

Does this year subaru have the cracking oil pick up flaw?

Or odds are do you guys think its the screws in the back of the pump backed out?

I have no oil leaks anywhere not a drip even after i tested it today saw no sign of a leak.

Strange part when the car was facing down hill the light would not flicker at all to barley flicker yet while facing up hill it would stay on until i turned the engine off quit quickly.

What do you guys think?

How do you know it's maintaining oil pressure? Do you mean the light is off?

Best bet is to get a temporary gage on it to see what the pressure is. Could be bearings going, oil pump going, bad seals inside, etc.
If the oil pressure is always on the low side of recommended, it's likely the oil pump.
If the oil pressure is OK when cold and OK when higher revs but low at idle, it's more likely to be large bearing gaps.

What weight oil are you running?

Presumably this '95 has pretty high miles on it?

Did you even bother to check the level of the oil after this happened? It seems like you jumped quickly to conclusions and never checked the level of the oil. That would be the first thing to do.

Like Pat said, letting us know how many miles it has will help, letting us know what weight oil you're running, how many miles in between changes etc...

140k for miles
the oil level is fine, had a oil change just a few weeks ago, i took it to the shop since i dont have time to rip it apart and it was the oil pump, the screws started to back out.

While not scientific no real slop in the main pulley, the car idles perfectly smooth, no vibrations when giving it gas, i've had this car for about 8 years and 100,000 miles.

I put a oil pressure gauge on after i posted this can if you didnt give it gas it would just keep dropping lower and lower, but giving it even a tiny bit of gas it would jump up to 20 PSI. didnt test higher RPMS because i didnt want to push my luck.

this will be my last repair which is a shame, I will sell it and get another subaru

That 22E is still just a baby. Sorry to hear you are giving up on it. What are you going to replace it with?

Got the car back and it was just the oil pump, its funny my mechanic who normally fixes taxi cabs who owns a subaru was like this pump should of lasted to 200k.

My wife who grew up in the city never learned how to drive and starting on a stick isnt that good for her, I am going to sell it to someone who hopefully appreciates that car. Its been to 20 states, pulled my bosses range rover sport out of a snow drift.
I bought the car right after i broke up with my first long term GF, And ended up taking it on my first date with my now wife.

Yeah it has no radio bezzle or cup holder because someone stole the aftermarket radio from it.

the door panel is worn smooth from my hand resting on it all these years.

I found another 95 22e with 41K on it in auto with leather, I dont like auto but it will be good for her since we are going to start a family.

Part of me would love a WRX yet they are horrible used, all of the ones i have seen have high milage and some kid beating the crap out of them.

When the time is right, we will get a second car and i will get a impreza and buy a JDM STI in canada, drive it into the states shhhhhhhhhh
and take it apart and swap out the parts and then sawzall the shell and scrap it. I dont like front clips since they really treat them like crap when cutting them up.

I would use castrol high milage 5w30 with a fram tough guards, and if they didnt have the castrol i would use valvoline high mileage.
oil changes where generally every 3-5 months or before any road trips,

Once a year I seafoam the intake and use a quart of kerosene to flush the engine for about 20 min at idle, After doing that i generally would put in cheap oil and and drive 100-200 miles before putting the good stuff back in.

Once a year i would also give the coolant a good flush.

the only thing that bad that happened to the car was i got same tainted hurricane sandy gas that clogged my fuel filter and jammed two fuel injectors open

^^^ I would advise the OP to use the Purelator PureOne oil filter part # PL14460 as it has the proper 23 psi bypass spec that subaru has spec'd for their engines. The fram oil filters DO NOT meet this spec.

I know of people that do a Kerosene flush, but I never have. I sorta have an issue with something I consider a solvent in the oil.
With decent Dino oil, oil changes & high miles, I have NEVER had sludge build up. Thus, part of why I never had the need to "flush" the oil areas.
If it works for you, fine.
I would never recommend it myself.

I always use the Purolator filters, never had an issue (unless someone ran the oil low.)

Also not sure how you got injectors "stuck" with sand, the pump sock should have kept it in the tank, a clogged filter (if sand got that far) should have shut down the engine before sand passed through.

Steve, glad it was an easy fix, hope it stays around for a while. The 2.2 NA's are pretty bulletproof and can last with general maintenance.
