I've always moaned about my 300TDI Defender having a noisy engine (clack, clack,clacking), even though most people think it's ok! (I've had 200's and 300's previously)
However, twice in a row it has been normal noisy in the morning on a 12 mile run (6mile, 1 hour stop, 6mile), but then when I've started it in the evening after around 5 hours, it sounded much quieter!
Next morning back to the clacking - any ideas please?

Have you checked your tappet clearances recently? Also, check the valve stem caps are all there.

What oil do you have in it and when was the cambelt changed?

As above, renew oil with good quality 10W40 and check valve clearances + cambelt and pulleys if time to change. Near all engines are slightly noisier on start up...by design, Land Rover lumps are inherently noisy...it's part of their character

How many miles has your engine covered...?

This may sound strange but I recon I can tell when my 90 needs an oil change just by a slight increase in noise made, and on mileage check it will be within 200mls. Change oil every 5k

Thanks everyone, cambelts fairly new and I’ve checked/reset tappets, so I’ll give her an oil change with some good 10/40

l had this issue on a classic car with a six cylinder engine and it was the oil feed to the camshaft that was blocked.
