This is not my car.
It's a v8 M62 engine - X5. It does not have the plastic guide rail. It's my friends car, and I took liberty to post here - some v8 folks might know how to deal with this problem. We think the timing is out by 1 notch (we believe the chain has slipped when the chain tensioner bit the dust). We don't know how to re-adjust the timing in this case.

Here is his original post from another forum:
"About a week ago, I got a noise coming from the engine passenger side and I parked the car back in the garage. Later that day I started the car again and the noise was gone for a few minutes than came back stronger. I thought was the chain rail but why the noise went away for a few minutes? When I get the noise the engine is also running rough and I got SES with P0011. There was a metallic noise plus something else. I took the valve cover off and noticed the tensioner was loose. I replaced the tensioner yesterday and the metallic noise is gone but I still have a lot of bad noise coming from the engine (left side/center) as in the link attached. Somebody mentioned that the chain might have jumped a leg and I would need the camshaft adjusted. How do I test to make sure that's the case? An indy said that it might be the camshaft adjuster but I didn't find any thread about this. It doesn't look like a common problem. I switched the camshaft sensors around and even replaced with a new one but no change. I have no idea what I should do next."
Engine noise

Doru, thanks for posting this. It feels good when you make friends through forums. This forums are very helpful.

Guys,
I have done more research and it looks like it could be two possible causes for this problem:
1. the chain jumped a tooth
2. the VANOS solenoid is not working

Now, for cause 1 I have to take the entire front down and do the timing. So, for this procedure I have to find a honest mechanic.
For option 2 I guess the front does not have to come off but how do I test to make sure the solenoid is actually not working. Not sure if I am right though but that's based on the reading I have done so far.

hey guys, what ended up being the problem, and how did you fix it? Today my car started to make that terrible engine noise. It started off where I could barely hear it at a stop light and within the remaining two miles to get home people could hear me coming. I scanned my car and came up with P0011. I am not the most mechanical person but do have some knowledge. I had a shop recently (1200 miles ago) replace the valve cover gaskets but other then that this engine had not been apart that much in the 5 years I have owned it. I was not happy with the shop I took it to and didnt feel like they totally knew what they were doing (I would have done it myself but I was crammed for time.) wondering if there is anything I can do to check and see what is wrong with it or if I need to take it to a (different) shop. Any input would be greatly appreciated.

On the E39 M62tu motor usually when you get the P0011 code and the engine sounds terrible, it is your u-shaped timing chain guide has broken. Drop your oil pan and look for pieces.
