Chain noise

[Jonty]

Hi all

Sorry another query. I’m noticing the main belt for the water pump etc sounds like if has chain noise. The noise is loudest around the bottom pulley. It very consistent and doesn’t sound like anything is grinding. It’s a brand new water pump so can’t it. Is this normal or potentially a bearing?

Perhaps you’re hearing the timing chain?

Potentially I am but its very noticable (can easily hear it from the front of the car). When I have heard loose timing chains befroe those it is more of a rattle than a consistent sound of a chain. Shoudl I hear the Delorean timing chain?

Are you sure it's not your v-belt slipping? what does your voltage with the engine running look like?

Possible it is one of the idler pulley bearings.

Thanks voltage is fine. What I’ll do is see if my local mechanic can have a listen to see if it’s a familiar sound before I pull anything apart
