2.25 Petrol Rattle

Hi All,
Just wondering if anyone recognises a kind of rattle my 90 2.25 Petrol has? See link at bottom of post.
Some background.
62000miles since 1985
When I first got the car running it did not have an exhaust so have no idea if it was making the noise at the beginning!
Because after I got it running I decided to get the head gas flowed and converted to unleaded at Turner engineering. Once I got it altogether again runs amazing, but with this rattle. Taken it to two garages one a Landy specialist and they both said could be anything don’t worry about it!
So 2000 miles on it’s not really got any worse, but it’s a bit annoying as i don’t know what it is.
I have had a good listen with a stethoscope and the only place I think I can hear anything is at the lower half of the timing cover???
Could it be the timing chain? Do you guys think it needs attention?
Would be grateful to hear your thoughts.
Thanks Paul

Timing chain rattling. Fairly easy to sort out if you just change the tensioner.

Thank you very much for your opinion on that! Looks like the front is coming off over the winter!

I had a Ninety with the same 2.3 engine in it, the timing chain rattled for about 10 years before I got round to sorting it. I fixed it in an afternoon, had I known it was that easy I would have done it nine years earlier!

Good to hear it’s not too complex job and hopefully I’m not doing too much damage driving it now and again.
I have to say It will be so nice to hear the engine hum with out the rattle!
Thanks for the encouragement!
