Question Noise Inside Engine? Mileage around 169,XXX

Anybody can tell me what's causing that noise in the video? I already checked my DISA VALVE by doing the unplugged method to see if the noise goes away but it is still there. Sounds like its coming from the engine. 2000 328i 169,XXX. THANKS!

I can hear it from under the car too. That normal sound doesn't sound normal to me. Lol. I don't know maybe it's just me.

Your right. I haven't checked my oil level for awhile. Sometimes when I turned on my car, the yellow oil light comes on for like at least 10 seconds then goes away. Assuming it also might be my oil level sensor which I might have to change on my next oil change. Anyways, here's a better hearing of the engine noise in this video. Could you guys check one more time in this video. I don't know if I'm going crazy hearing things since FAST BOB assumed its normal for it sounding like that. FAST BOB, maybe this video might change your answer about noise being normal. Thanks

OK, I`ll revise my previous statement:

"It sounds pretty much like a typical BMW with a cheap, sh!tty aftermarket intake on it"

Feel better now ?

LOL. That didn't help the noise situation I'm having, but your comment did made me laugh. Haha. Yeah I do have a ****ty aftermarket intake. i'm going to get a better intake one day. was thinking of getting AFE Stage 1, but I have xenon lights and it says it doesn't work with xenon lights. Anyways, bought the car like that and found out that it was a homemade intake tube with beat up dinan filter as you can see. I brought the old beat up Dinan Filter to DINAN Service one day and bought a new one i think for around $70.00. Next day when I try to install it, the diameter was the same as the mass air flow sensor, so the new filter couldn't go over it. Should checked it right there at the spot. They measure it and told me it would fit. Anyways they didn't have a size for my ghetto intake tube, they had a one but the diameter was too big which would make it be loose even with the clamp. So i ended up returning the new dinan filter and got my money back. They offer me to get K&N cold air intake with the heat shield, but didnt had the money. So as of right now, car still running with the beat up dinan filter. LOL. Too much info. Sorry got carried away. Haha. Here's the one that's on my car right now versus what could of been on my car

Sorry to break the news to you, but yes, that is an abnormal air filter. haha Still cruising around with that "Thing" under my hood. The sound of it when i go full throttle is not that bad. It's still holding up. Don't judge the filter by the way it looks. HAHA I should record a sound video of it and post it on here. LOL. It's not even an cold air intake. It's a homemade piece of crap intake without heat shield. haha. FAST BOB, gonna have to agree with you on that.

I remember i had serious problems getting my K&N CAI to fit my MAF, ofcourse it's good when they fit as tight as possible, but i had to cut rubber tube bit and make it sloped and even then lubricate it bit before i was able to get it on.

The video in post #5. The knocking sound when I keep on getting closer to the engine. Don't know what else to describe it.

Knocking sound?
Ok, that's what i thought, but wasn't sure if you're thinking about same thing.
As if i understood it's typical for old BMWs and normally comes from valves/camsaft.
It's cause of oil not flowing up to the head so well anymore like used to. Can try to heal it with different quality motor oil, but eventually some wearing parts will need to be changed.

You`re aware that BMW`s infamous DMFs (Dual Mass Flywheel) are prone to sound like cement mixers when they`re beginning to fail, right ?

only when clutch is released this sound appears. if he presses the clutch that sound should go away, right ? (if this is what he's suffering from...)

What you`re referring to is throwout bearing noise, DMF noise is different.

That's what hear inside my car too. It's not loud, when radio volume is off and everything is silent, i can hear this really small low noise when the clutch is release. When i press on the clutch, sound goes away. It's not the issue i am having on this topic, but is that normal? This is when of course, the engine is on and idling.

No I wasn't aware of that, in fact that's a new term for me "DMF". Still learning as I go. Any other ways to find out if my DMF is going bad? Any tests I can do? I hope my clutch isn't going bad.

Throwout bearing noise (a *little* bit of noise) is fairly common, and is usually nothing to worry about.

Perform a "slip test" on your car. Drive on a level road at 35 mph in 4th gear, and floor the throttle. If the car begins picking up speed immediately, without hesitation, the clutch is still good. If the RPMs jump way up without much immediate increase in speed, the clutch is slipping and should be replaced ASAP.

If the flywheel goes bad, you`ll know about it !
