Oil Light Comes on at Idle

Car: 2002 9-3 SE 2.0T HOT - 110k miles (ish)

This is my sister in law's car. She just picked it up, we knew it had a sludge issue that was fixed before we purchased the car. The screen/pick up/oil pan was cleaned as well as the PCV hoses replaced. And it was done at a shop that I trust.

She's been driving the car for 3-4 months now, and the oil light just started coming on at idle (when the rpm drops below 1000).

What do you guys think is most likely? Oil Pressure Sensor? Oil Pump? More Sludge?

more sludge, unless there is an oil leak at a main seal

Sludge or silicone clogg.... does the shop that did it know NOT to use silicone on oil pans? Do they know what the term "in moderation" is? If they are a good shop and you like using them - see if they would cover the job again if it wasn't that long ago - or meet you 1/2 way IF it has anything to do with the work they did to it.

Sounds like it's prob. starving and should have the pan dropped - cleaned and a new screen put in if it's too far clogged with sealer.... Perhaps the pick-up screen tube or the cross over pipe did not get new seals and it's leaking past dropping pressure.

make sure the oil cooler is not plugged. drive it for a while and see if the cooler is hot to touch. had this problem in 2 9-3s recently, oil light would only flicker after a drive on the highway. (one was a sludge car, other was a bad t-stat)

Very well could be oil pump. Typically they scar up the pump and the cover making it harder for it to make pressure.

As I posted and withdrew yesterday ("Nevermind"), when bearing clearances open up due to lack of adequate lubrication, a new pump and cleaned screen won't help. I hope, for her sake, it's not that. Get a true oil pressure reading and compare it to what it should be. Good Luck!

Thanks guys... Looks like a trip into the oil pan will be in order. I'm also going to call the guys that fixed it last and see what their thoughts are... Let's hope we're not too late!

Oil viscosity maybe? You're in Wisconsin, maybe her car has a very light oil for winter, a heavier weight oil could help out now that ambient temps are higher. I see this all the time here in Alaska (not on my SAAB, but on many cars of various brands).

I actually have no clue what weight oil is in it since she hasn't even put 2000mi on since she picked it up, and they had just changed the oil... I'm going to drain the oil, drop the pan and check it out. If it's not all sludged up (or full of metal shavings) I'll go with 10w40 Mobil 1 and see how that does...

It's kinda funny having to put 10W40 M1 in it, since I'm use to putting 0W20 in our '04 9-3, '07 9-5, and in my wife's '10 9-3... I even put it in my '92 9k with no issues...

Well, if you still have oil pressure at low rpms maybe I'll put that in her car... LOL

Ok, more info on this. I haven't had it apart yet (since she just dropped it off) but the light only comes on at idle once the car is warm.

Wrong oil weight?

I still want to pull it apart for good measure, but just curious on your thoughts.

Also, I'm going to do the PCV update since it's here...

And the survey says....



Sludge!

Yes, it has been ventured into before. I could tell by the excessive amount of red gasket maker... When I asked the guys we got it from (the shop that worked on it as well) they couldn't remember if they had done it, and had no record in their computer (I would have sworn they said they did)... Anyways, it's getting a new pick-up, new o-rings, the oil pan cleaned out, and everything buttoned up... It should be good for another 100k plus... Oh yeah, and the PCV update...

The one thing that made me worried was that there are metal shavings in that clump of sludge. What are your guys thoughts? The engine doesn't make any bad noises and it runs like a top...

If the filter is still on it cut it open and look inside the pleats, also stay away from the Fram filters, they are crap. You will see all sorts of metal inside the filter if there are things going wrong, just make sure you put the filter material in a vice and squeeze out all the oil so there is less mess.

I'll cut the filter open tomorrow when I'm back in the garage... It's not on the car anymore, but I still have it. It's in my waste oil pan...

What size and grade are the bolts? Bolt torque specs for socket head cap screws for machine repair assembly bolt torq CNC These charts are almost always for steel threads so if bolting to aluminum its MUCH lower.

Tight enough - but not too tight.

OR - if you have a good torque wrench I think it's like 16 ft lbs

Thanks for the help! It's back together, I'm going to run it another 5k, then pull it back apart and see if I find more metal shavings. If I do I'm going to replace the bearings. Thus far the oil light isn't coming back on so that's a good sign, but only time will tell.

While I was in there I did the PCV update, and wow I couldn't believe how bad the hoses were. One was practically melted off.
