oil light flutters when idling

[g2sh0]

i checked the oil level and its fine. but when im idling when the car is warmed up the oil light flutters on and off.. and sometimes just stays on. im thinking its the pressure.. but how to i fix this problem?

Sounds like maybe pump or bearings. How many miles on the car?

 

[mooseSHO46]

Maybe the bearings have they ever been done? how many miles?

 

[g2sh0]

125,000

 

[mooseSHO46]

Have the bearings ever been done?

 

[g2sh0]

i got the car at 120.000 from some old lady.. so prb not

 

[sho2see]

two words...Rod Bearings!!
I would not drive the car till this has been chnged

 

[Brett]

Do not for the love of god, drive that car anymore. Bearings are cheap, motors aren't.

Have you changed the oil since you bought the SHO . . . ?


That's the one thing I have always done religiously, as soon as I took possession of a [new] car - is change the oil.

Not to be the bearer of bad news, but given how cold it is outside, getting a Low Oil Pressure light this time of the year suggests the bearings may be shot. However, . . . .

First, I would change the oil pressure sending unit, as it is possible that the sending unit is providing erroneous data. Second, I would get a secondary means of measuring the oil pressure (eg. a mechanical oil pressure gauge). Third, I would change the oil to a 10W-40 oil. Fourth, I would stop driving the car until I got at least two of the three above items done. Fifth, I would call the prior owner and inquire about the Oil Pressure light. It seems unlikely that this just miraculously happened immediately after you bought the car !

Either one of two things is happening - either you're getting a false low oil pressure indication, or you're getting dangerously close to spinning a rod bearing (or two).


Where are you at in Illinois?


:wave:

 

[g2sh0]

yea ive changed the oil twice now, every 2,000 miles or so. i got the car august 2007 i used mobile 1 this last oil change. and the light started a couple weeks ago.

im in Naperville near Chicago

Where would the oil sending unit be located at. on what side of the motor?

The oil pressure sender screws into a port on the block on the underside of the engine. From underneath, find the oil pan drain plug, then go up. You will pass the low-oil-level sensor in the pan, and then as you go up more, past the pan, you will see a sensor screwed into the block. It's a one-wire sensor, I think. The plug pulls off, and the sensor unscrews. Read about how to replace it and seal the threads, etc.

 

[mooseSHO46]

i would just do just bearings just in case too

 

[g2sh0]

yea thats what i was thinking... better safe than sorry. im gana end up replacing the bearing and the sensor.

Just to make sure... we are talking about the red light, yes?? If so stop driving the car and have the rod bearings changed ASAP.

It's more likely that your bearings are on their way out. I had a similar problem except my light only flickered when I revved and let it drop. After a while it got worse and did it more often than not. Once I changed my bearings I never saw that oil light again.

Definitely do the rod bearings, you have everything to gain and nothing to lose (except a bit of cash, but that's better than losing a motor).

 

[hawkeye18]

why is it necessary to have two threads on the same suject by the same person...?

 

[Kens1992mtxSHO]

I was thinking the same thing. It drives me nuts thinking to myself "didn't I post here already"

 

[shospeed]

I agree with everybody !!!
Rod bearings !!!
Change them and you are all set !!
