Please help with knocking noise

queenb1981

I have a 2001 picasso with 65k on clock with full service history at citroen. I have recently been hearing a knocking noise when warm when pulling off and reversing. Sounds like its coming from engine area, any ideas????:mad:

Blimey, I hope it's not the big ends! Could be the water pump bearings, I suppose, but you need to have a mechanic take a look at it. We can't diagnose from a distance without hearing it.

I am starting to panic coz 1 garage said engine gone!!!! another said its water pump and a third 1 said he doesnt know. How can i pay for work to be done if i get loads of different answers. It drives perfect when cold

and when you are driving along

Can you be more specific about what you mean by a knocking noise. Does this knocking happen at a specific RPM? Is the knocking continuous or intermittent? Is it a light or heavy knocking?

Do you belong to any road assistance organisation like the AA?

If so you could pretend it's only just happened and call them out. See if they can offer an opinion.

It happens when you are revving enough to pull off (dont have a rev counter sorry) knocks around every second untill clutch is fully released and are moving along. Its loud enough to hear clearly without trying to listen, quite heavy i would say

If you rev the engine - does it come and go when the clutch goes up/down?

Have you checked the 710 recently?

queenb1981

Does the car shake when you turn the engine off?

Check your engine mounts, especially if the noise changes in reverse.

Another option is to allow the engine to cool down completely, and remove the fanbelt. Obviously don't drive it for more than a minute while doing this, as the water pump won't be circulating coolant. If the noise goes, you know its fanbelt related.
