Thread: Odd Engine Noise

Hi All,

I have an odd noise in the front of my TDi 300.

I recently had the radiator replaced and in the process put in all new hoses, bearings,and a coolant header bottle.

The noise sounds like a bearing in failure mode. Its not consistent (it comes n goes), at idle it disappears after a few minutes. I've listened all around the engine and I'm stuffed it I can find it. I don't have time to fiddle with it so its off to the resident Landy expert to look at.

My main suspicions are

Possibly the fan hub bearing but it was fine 4 weeks ago when it was last in pieces.

Camshaft Drive Belt idler or tensioner. Shouldn't be as it was replaced @ 40,000k and it now has 67,000

Injector Pump, God I hope not.

Let me know your thoughts please.

Cheers

Well,

For those who are interested.

When the vehicle was purchased it had an alleged 37,900k on the clock despite being 8 years old.

When I got back to Tassie I took it down to Justin and he fitted the factory timing belt kit.

Because of the the odd noise that has been coming from behind the timing cover I assumed (correctly) that there was something wrong with the injection pump.

On closer inspection there was a considerable bit of belt dust from what I'd describe as premature belt degradation. The idle roller had a grumbling bearing as did the tensioner which was even worse.

Whilst it (the belt, tensioner and roller) were no where near failure its a bit of a worry that they had only done 30,000k

If anyone has had a similar experience please let me know.

Regards,

Adrian
