Help II - 2.4d DW engine - Noise when revving

[blix99]

Hi. Thanks again for the reply.

So, I did decide to buy new injectors but they are set up for DV engine (D2.4t so I understand)

I have fitted them as I needed to get the engine going again (and van moved) and it's much better now. Thanks for all your observations and advice : )

So (more questions : )
What is the difference with internal setup of DV injectors and what will the effect be when using them in my DW engine with DV settings as opposed to the correct settings? Short term / long term - performance, fuel economy etc. Mainly though; will it damage anything?

I guess all of the different settings are defined by the shims above the spring and hence the spring pressure / tension?
