Evening all,
Just a query about the TD5 engine, as I'm new to these having had many 300TDi's. It's in a 2004 Discovery 2, all totally standard, 129K miles.
At different throttle openings the engine noise varies. I know this sounds obvious, but I'm not talking about volume. At very light throttle openings in 3rd or 4th it can sound a little rattly, as it does too on the over run. Under wider throttle openings it is quieter and very smooth, no smoke, all as I would expect it to be. Just seems a bit strange that the 'tappety' sound is greater under no or low load. I have changed the oil last week, used Shell Helix 5W30 as per the recommendations. Definitely sounds like tappets.
Doesn't sound serious, just curious!
Any thoughts welcome.
Thanks, Julian.
