Hello,
Does your car have a manifold/cat heat shield in the engine bay? Have you checked it isn't loose? They are very easy to bend, maybe it's been lent on and is contacting something.
Cheers,
Jon.

Rattle/Vibration in engine (N52) when hot
I'd forgotten about this clip I uploaded to youtube - you can hear the noise at 54-56 sec. The engine had warmed up before revving so the noise was happening.
I'm leaning towards it being some heat shielding after listening to a few other clips online. I will have to get it up on the ramps and have a poke around.

Indeed I hope not too. I am the unlucky git who has no hair left... But philosophical about it. I need to update my post. But in essence £1200 down ex labour in essence and no resolution. Engine idles fine and runs perfectly at the moment and if you were deaf you wouldn't know the difference. Heat shields all checked and obvious stuff too plus all timing chain, guides, tensioner, hubs replaced, oil filter housing checked, oil strainer.... Just living with it so if it doesn't effect your engines performance I'd recommend living with it unless you have deep pockets...Marlon wrote: ↑Thu Feb 01, 2018 5:23 pmI hope not for the OP's sake - absolute nightmare that threadph001 wrote: ↑Thu Feb 01, 2018 4:39 pmDare I ask if it sounds similar to this?..... https://www.youtube.com/watch?v=cgtHUhG ... e=youtu.be
Here are a full 9 pages to read on it! Still don't think the mystery has been solved as far as I know

Sorry to hear about your probs with the engine - I'm hoping mine's nothing more than a heat shield rattle, but haven't had time to put it on ramps to check yet. I'll update the post when I can check.Cooky3 wrote: ↑Tue Feb 06, 2018 10:02 pmIndeed I hope not too. I am the unlucky git who has no hair left... But philosophical about it. I need to update my post.
