Horrible noise from the engine (video attached)

sergg · 11-17-2012, 05:19 PM

Hello all,

My 325i had oil leak from the oil pan gasket and unfortunately lost a lot of oil without me realizing and I drove the car with very little oil for about 30 min, what is strange is that the engine did not overheat at all but the engine started making this horrible noise.

After having the oil pan gasket replaced the noise didn't go away , the car runs just fine but I am afraid I damaged the engine

, any thoughts out there?

VIDEO :

thank you!

Here's an idea... Hold the gas pedal at red-line until whatever is coming apart shoots through the oil pan or side of the block; then you'll know what it is!

Don't want to kick someone when your down but revving the engine to show us, is probably the worst thing you can do! I'd encourage as a starting point that you drop the oil pan and take a good look around; whatever it is it's spinning' metallic and probably making shavings.

Good luck!

Running an engine out of oil doesn't make it overheat. It fries bearings. That doesn't sound like typical bearing noise, but I'd say whatever it is probably isn't good news. Maybe try a piece of hose, screwdriver, or mech's stethoscope and isolate where the noise is coming from. That could be a coincidental pulley noise/belt...but I doubt it.

I noticed that your oil light is on.Did you recheck the level, maybe start with that.
