The engine in my rallye was knackered, a proper tapper. I took it out and replaced it with a 2002 Xsara lump at the start of my project. I had been in the car it was out of and the engine was sound. I decided to change the cambelt as a precaution of the engine standing in the car whilst I was away.
I had always cranked until well after the oil light went out before starting. When I finished in the bay with piping everything up I ran the engine a dozen or so times, and it definitely got properly warmed up on at least two occasions - one on the new oil last week when i was testing the fan operation - didn't hear this noise at all.
I have recently changed the cambelt thanks to a helpful member on here. I used a new genuine Peugeot 136 Cambelt kit with new tensioner and roller. The water pump was also changed at the same time. At the time of the belt change, it was started and it sounded fine, but was switched off after 15 secs or so as it needed bleeding.
Last night I took the car up and down the drive a few times to check for noises on the suspension which has all been apart, the engine was warm for the first time since the belt change and I noticed it making a noise I hadn't heard before. I can't pinpoint where the noise is coming from so I wonder if anyone has heard this before.

It is not the crank pulley, as I used the one which had slipped a little off my old engine and it was exactly the same. It's also not the auxiliary belt circuit as it does it with the belt off as you can see in the video. The noise isn't there when you first start the car, it only really appears as the oil gets sufficient temp to start nudging the needle on the temp gauge. There is tons of oil sloshing around the head under the oil cap and a sump full.
I am a bit lost for words to be honest, it sounded beautiful before the belt but I don't see anything wrong.
As you can hopefully hear it doesn't sound like a knock it sounds like something is rubbing maybe.
Is this maybe the belt a little tight? I can turn the belt about 45 degrees I think on the run from inlet cam to roller. I'll have to check that.
