I have recently changed my old TDi Defender for a 03 TD5 (30K miles). It runs well but when cold is noisy (sounds like an old Leyland bus rattle). The TDi was fairly quiet hot or cold. The power seems OK when cold and when it is warm it runs like a dream with plenty of power. When the turbo kicks in it is much smoother, hot or cold.
Can anyone tell me if this is normal, and if not, offer any suggestions what to do?

Thanks

Darryl

Could be due to a play in one of the pulleys engaged by the auxiliary belt..... after a while or on higher revs they used to center themselves
 
When cold they can be uneven, owing to only having 4 glow plugs on a 5-cyl engine. That could be what you are experiencing. Also as an experiment you could try adding two-stroke oil to the diesel (about 300mil to a tank). Many people say this gives quieter cold running (and some say it don't, but worth a try).

Hi Shifty: on the td's timeing belts seem to be a issue. Is there a after market belt made of better materials ?

TD5 does not have a timing belt. Later TDis had an issue but the problem was with a misaligned pulley, not the belt. If the engine has survived up till now it will almost certainly had the pulley modification.

Am i right in saying its the same as the Defender injun and it only has 4 glow plugs:eek:, hence the rattle sometimes when there cold.....

The only reason it isn't leaking oil can only be that all the oil has fallen out.

On a cold start the ECU heats the glow plugs (all 4 of mine were U/S last month when I checked them) and the ECU attempts to start the engine ON FOUR CYLINDERS ONLY. The 5th injector is not energised! This is to stop unburned fuel vapour from cylinder 5 going down the exhaust pipe and into the Catalytic converter. Crazy system!

Once the engine has picked up speed to at least tick-over revs the 5th injector will then be energised as the compression alone in Cylinder 5 will happen fast enough to initiate ignition without a glow plug.

I wonder what LandRover did with all the money they saved by fitting FOUR glow plugs to a FIVE cylinder engine.
