Oil Pressure Light On - BMW Forum

crystals1977@hotmail.com · 09-29-2009, 10:37 PM

I Have A 2000 528i The Oil Pressure Light Came On And The Vehicle Was Driven Approx. 15 Minutes. Noise Is Coming From The Engine, And It Does Have Oil. I'm Not Sure If The Noise Is A Lifter Or Possibly Just From Running Dry. Does Anyone Have An Idea Of Where To Start I'm Not Sure If I Need To Look At Sensors, Pumps Etc. When I Rev Engine, Oil Light Did Go Off Momentarily So The Rpms Must Be Giving It Pressure. Thanks

Don't even turn it over again until oil is added to the right level. I hate to say this, but engine damage may already exist.

It Has Full Level. What Kind Of Damage Am I Looking At.. Thanks

If it still runs, it may have piston ring damage and cylinder scoring; it will likely tend to burn a lot of oil without major repairs.

Do You Think It's Better Just To Drop A Different Engine In It.

You would need to run it for a while to find that out.

So do you have blue smoke out of the exhaust ???, It sounds to me that maybe your oil pump went or is going,as you say you had oil in but no pressure.

+1 on the oil pump idea...

is the car leaking oil from anywhere?

Hook up a mechanical pressure gage to get the engine oil pressure before you tear into it.

I Do Not Have Any Oil Leaks Or Blue Smoke From Exhaust. I Just Replaced The Vanos And Valve Cover Gaskets Approx. 3 Months Ago. An Oil Change Was Done 2. There Has Been No Forewarning, No Sudden Drops In Pressure. Since The Vanos Was Replaced The Car Had Slightly More Power And Better Fuel Consumption. I Do Have High Miles I'm At 170

Has the oil pressure sensor been checked?

crystals1977@hotmail.com · 09-30-2009, 09:01 AM

No, I Have Not Checked Anything Yet. I Was Asking For Ideas Before I Just Started Tearing Into It. I Was Concerned Because Of The Engine Noise And Was Wondering If It Was Worth Digging Into

You havent explained what sort of noise ???
