Engine noise help!

Any ideas what they issue is here? Car has only covered 55k, full service history, just changed oil and checked filter, checked tensioner, checker injectors and no black around seals.

Noise is coming from top of engine not bottom.

Car is silent when cold started, appears after 3-4 minutes of running.

Any help or ideas would gratefully received

Did this noise occur after you changed the oil?

Please update your profile to include the year, model (is it GAS, CDI or Blue) and where you live.

Odd as using my phone I profile is correct.

UK based car and it’s a CDI model.

No it has done 2k since last oil change and I have just completed a oil/filter change using 5w-40.

No different.

When you joined this forum this month, why can't you use the same procedure to enter the year ?

Ahh ok so I’ve now added the year next to the model.

Sorry, UK forums do not focus on having the full info on car in profile. Usual prefer the details in the post/thread.

Have you checked the oil level via the Inst. Cluster and with the dipstick?

Do you have an Owner's Manual?

It says in my first post I have just carried out a oil and filter change. So of course the levels are fine.
