Never heard of mechanically noisy electronic pumps, they usually stay silent right up until they fail & fry your engine :cry:

Thats worth knowing Rob, thank you.
From what I've picked up on here & my own experience they tend to fail electronically & not mechanically-mine rhythmically pulsed the radiator fan immediately after cold starts which is early warning of pending death throes :roll:

"pending death throes" very dramatic, love it.... Personally I would say "gonna pop its clogs" :thumbsup:

I am beginning to think that this is the timing chain and/or tensioners-guides.
Yesterday it was quiet as a mouse for 3 hours while messing around with Carly, today it sounds like a ball bearing is rattling around inside...

Those engines aren't renowned for chain/tensioner issues, have you tried the long screwdriver "stethoscope" test to try & pinpoint the noise?

Yip tried it to no avail. Their is a small valve in the side of the engine block according to diagrams on realOEM website. Might be that, or I need a longer screwdriver! I think I will drop it round to my local indy and see what they say.
