UPDATE #1 ON PAGE 2

Hello Xoutpost,

I have a 2003 x5 4.6is with 160k miles and it just recently developed this loud ticking/knocking noise. I just wanted more opinions on what it is but i am pretty certain it is the rod bearings...

Notes:
-car ran and sounded very smooth about a week ago. only noticed a knock at initial cold start up then it would immediately go away
-been driving the car about 4 days a week ~20 miles each day
-car knock started to stay when driving the car and has been getting worse
-checked oil level and it was low 2 quarts so I added oil hoping the noise was the hydraulic lifter tick. the noise persisted after adding oil
-Decided to do an oil change and found gold/copper colored shavings in the oil filter and housing (this to me seems pretty obvious that it is from the rod bearings)(oil used was castrol 10w30 fully synthetic)

This may be a pointless thread but i'd rather get more verification before i start tearing into the motor.

here is a video to help give you an idea:

at 00:49 seconds the tick goes away for a couple seconds
also at 01:33 the tick goes away when i rev the motor

Thanks in advance!

But really, that doesn't sound too good man. It's hard to tell from the video. Have you tired the hold screwdriver/stethoscope trick?

It may not be a Rod knock. But why was it 2 quarts of oil low to begin with? Thats alot of oil off the mark. I would imagine that if it was a rod knock that you would see some drop off in oil pressure or some oil warning light come on in the vehicle. Maybe its the timing chain up front. In any case you are going to have to rip down the front of the engine and see what you have.

I just wasn't smart about checking the oil. I checked the oil level when I bought it and it was at the half way mark on the dipstick and I did not check it over the past 2 months. I must be used to the warning on my e90 that tells me to add 1 quart. The low oil warning light never went on, on the x5 either.

I tried with a screw driver but can't really access much. I will go out and by a stethoscope. It is so difficult to tell where it is coming from

Have you tried the coil off procedure that I listed in another thread?

I would try Upallnight suggestion as well as connecting a oil pressure gauge to see what the actual pressure is. Good luck

There's too much happening/noise in there.

Gut feeling.....Sounds like loose spark plugs.

Maybe a timing chain tensioner? No fault codes with this noise? I've seen where an oil gallery was plugged and oil to that bank was restricted causing that kind of noise. This also caused a fault code.

I know those engines, they are great when they are running right, but suck when You have problems, be prepared to spend a lot of $$$$$$, or better off get rid of it, I hate to say that but.....
