Again need help for the this noise on cold start for 5 minutes.

Sounds like timing chain slapping against something, whether it’s the timing chain cover or something else.

Heard of the hydraulic tensioner needing a bit of pressure and warm oil before it tightens up and that sound goes....

Still not good! Look it up and see if the sound is similar for other 3.0 but it really does sound very similar to be honest.

The fix in itself is pretty expensive too!! 😭

How does it sound when you rev it?

Timing chain is more of a rattle.

Thinking out loud, this sounds like it could be a small split/crack in the exhaust manifold! How long does it take to stop?

Perhaps the timing chain runners it’s hitting shading im thinking, but the sound it’s metal on metal sound. if the exhaust was spilt or cracked I still couldn’t imagine this sort of sound unless it was loose but then it would still rattle against soemthing.

Does the OP have a solid flat head screwdriver and put the the flat part to the engine and your ear onto the handle to listen in? Could be coming from the core of the engine.

P.S. post the resolution or even the reason for tapping pls! I’m intrigued!

Alex, The garage I have given my car in said it's not from the engine it's from the gearbox, and it could be oil. He recommends someone in Reading to look at it. So I am stuck.
he said the noise goes after 5 minutes so it seems the oil flow. so need a proper diagnosis @Alex1990

Booked it in for a cam chain change. The second garage said its defo a cham chain so let see the cheapest I got so far is £870.

Hopefully they’ll find the reason for the cam chain rattle while they’re at it, so it doesn’t repeat. Make sure they check the runners aswell for tell tale signs!

Glad it’s sorted, shame about the cost!

enjoy the car again now! 👍🏻
