Flickering Oil Light, This

Camry LE 1997 180k, did oil change less than 2k miles ago (start of summer)
Also replaced oil pump at 178k in spring.

Had the dreaded Flickering oil light less 1/4 of a mile from home at a stop light, so I drove slowly. Only seemed to appear at a stop. Have read/watched a lot. So here is what I have done so far,
Oil Level is good
Oil color is golden clean
Oil filter is clean
Pulled out PCV valve to verify if any oils there are cloggy, it's clean.
Oil pressure switch wire is clean
Oil pressure itself is clean,

Question 1
but this I don't know how to tell if it's aok or not? It's cheap enough to pop a new Duralast Oil Pressure Switch here (unless you guys don't think this is a good quality?)
I will also grab a test kit from HFT.
If non of this checks out I will drop the samp.

Question 2
Anything else you would be checking before samp drop?






1997 Camry LE 2.2 178K and counting strong.

not familiar with the dreaded flashing oil light but assuming it's because of oil starvation and that you're using the same weight/type oil recommended for your engine and further that that you used a decent filter (and didn't leave the old rubber gasket on), i'd drop the pan and see if everything's good down there and then pull the valve cover and see what that looks like.

Should I not check oil pressure at this point first before dropping pan?

yes, if you haven't confirmed the pressure switch is good, then replace that first for sure.

Yes, I would advise before pan. You should use a manual tester to verify pressure. New pressure sender is cheap try also. Are you sure there are no problems with loose wire connection?

I'm assuming the light flicker stops when revs get up?

Wire feels firm but how to establish if it is ok or not? In light of info below (low oil pressure) this does negate the issue being the wire, correct?

Yes.

Changed pressure switch, after about 5 minutes of idling oil light started flickering.
Hooked up pressure kit, pics below are at idle 700 RPM, pic 2 at 3000 RPM
What do you guys make of this?

No oil starvation, on top and below this car.
Oil Wally Supertech 5/30 Full Synthetic
STP S4967 with new rubber
Can anyone chime in on STP quality?

+1 on testing with pressure gauge. Looks like a true low oil pressure problem and not a sender/wire problem. Typical places to look would be excessive bearing clearances, oil pump bypass valve stuck open, balancer assembly bleeding oil pressure.

See if there's metal debris in the oil pan.

BTW the needle wasn't twitching (Eric car guys talks about that)

What causes excessive bearing clearances? How do I check for excessive bearing clearances?
"....excessive bearing clearances, oil pump bypass valve stuck open, balancer assembly bleeding oil pressure"

This is a new territory, any pointers on further info, step by step, would be welcome. Thanx in advance.

- oil pressure at 3k rpms is good/spot-on at 30psi
- did this problems start before or after your replaced the oil-pump?
- whats the oil pressure at say 1,000 rpm? 10psi?

- make sure your 'new' oil pump had a relief valve in it!

- low pressure at idle, but normal at revs typically means something at the source is open or clogged:

- ie, relief valve open/missing, oil pickup screen clogged/dirty..

wear. Pressure is created by restriction. Less restriction (ie space between parts) means less pressure...

I'm thinking oil pickup screen dirty too...if it was me, i'd pull the pan next...

Oil pressure is a measure of resistance to flow - unless the oil pump intake is restricting flow. Even your 3k rpm pressure is low compared to mine. So what's happening when the oil gets warm is it thins and offers less restriction. Pressure does not separate bearings, oil shear does, but you need enough flow with a pressure differential to keep oil flowing between friction surfaces. The oil pump relief valve is a spring valve that prevents over pressure, if it's stuck open (broken spring) the flow will bypass the engine.

You could do an oil analysis to see if undue bearing wear is not restricting flow enough to raise pressure, but that would not be a sudden occurrence. The metal content will tell you something. Test about $30 at Blackstone Labs.

I'd replace the filter and see what happens - if you haven't done that already.

See pics below. I just started it for 2-3 minutes. First pic at idle 900, 1000 and 3000. These numbers seem different than the previous I posted, then it was idling for 6-7 minutes. Does this change your assessment?

Not sure how to make sure?
Are relief valves known to fall into the oil pan?

ahh I see the pics now...

ya, not normal... generally you want to see ~10 psi for ever 1,000rpms.. more for cold oil/weather..

- is the filter good and clean (you ARE using an OEM Toyota filter right?)
- otherwise time to drop the pan and inspect the screen
- rip off the oil pump and check the relief valve
- other than that can't think of anything else to check that's 'easy'.
- low oil pressure is deal breaker, so unfortunately you gotta get in there to save her....
- nice wood-grain dash BTW
