Thread: 300TDi Chirping

My bet would be the water pump pulley is slightly out of alignment. Happened to me twice.

If you take the timing cover off again, check that the belt or pulley is not touching the inside of the timing cover, it should show a wear mark if it is, Regards Frank.

I would say check the auxiliary belt tensioner. This is a common problem. An OE spec one costs £60, cheaper ones cost £45. To test it, squirt some WD40 on the tensioner with the engine running. The noise should temporarily stop, but it won't cure it.

So if none of the Ancillary equipment was connected and the noise is coming from the front of the engine then it has to be coming from the only moving parts, i.e. the timing belt and parts or the crank damper, or there is a bird stuck in the radiator, Regards Frank.

Thanks for all the replies guys.
I drove home from work last night with the motor sounding like a demented budgie. So this morning I wnet for a drive to warm the motor then once again stripped the front off it right down to timing belt only and started the motor which was warm and hey no noise. So I had a wee nosey around again and decided I needed to loctite the big cupped thingy (dirt shield?) behind the front pulley onto the pulley as it was a very very slightly bit loose and I needed to make a new paper gasket for the single bolt that helps hold the timing cover on as it was looking sad.
At every stage of the reassembly I started the motor to listen for noise but heard nothing strange.
The only bugger moment was when the fan shroud decided it had had enough of being twisted to refit and snapped but a couple of cable ties placed like stitches sorted that.
So now I have a reasonably quiet 300TDi Discovery but to be honest I have no idea exactly what fixed it.
Oh and I can get the front off my motor down to the timing belt in 15 minutes, no need to remove any hoses or radiator.

Good point, well made.

Timing belt tensioner or idler? Did you buy a kit with idler, or just the belt?

I did fit an idler and tensioner but nothing wrong with old ones.
