I know this is the section for E30's but its the closest to the 02 on the site so here goes. I was driving down my local canyon road which i travel almost everynight and everything was running well like usual. No unusual sounds, nothing knocking or grinding...but all the sudden the oil pressure light came on so I immediately shut off the engine and coasted and pulled over at the first turn out. I had the car trailered to my house where I was able to check some things. First, there is plenty of oil as I had just checked and filled it that night. I re checked and none had leaked out.
I thought the light might just have acted up, so I started it up real quick. It idled fine, but at around 1500-2k rpm's i heard what sounded like bearings knocking around, however still no grinding noise. The light was still on though. I just got an electric oil pressure gauge so I can double check that it really is a pressure problem and not something with the light.
I was told by my parents mechanic (I have never taken my car to a shop since I used to be in shop in high school until I graduated) and he told me that the oil pumps are pretty indetructable and usually don't go out.
I think I am getting some pressure because it idles w/o instant problems. If there was zero pressure I'm sure it would seize extremely quickly even at idle. Although with no strain on the engine it might not.
Any help or suggestions you guys could give me would be greatly appreciated. I know its hard to know anything without having a reading of pressure, but I will hopefully be able to get the gauge attached within a few days so I can post my results. Thanks for any help you can give me.
