Partner 1.6Hdi 75bhp Rattle from Engine Bay

[Ppartner75]

I have a 1.6Hdi 75hp with 91,000 miles on the clock. Serviced every year by reputable company. I bought the van 2 years ago and continued this service routine starting with having the cambelt and water pump being replaced at 88,000 miles with a full service in 2023. Over the last couple of months I’ve heard this odd rattling sound from the engine bay on the cam cover side. The sound disappears when the engine is warm. I’ve taken a video. Any ideas what it could be? Thanks

Any ideas?

Difficult to say - you will need to get a long stick to listen direct to the individual components to see which is making the noise.

Thanks for your reply, Richard. Much appreciated.
I’ll give that a go. I might also remove the aux belt and start the engine briefly to listen for that rattle.
