Injector noise on 1.9 jtdm

Hi all I am just looking for a little advice I was running the engine today with the engine cover off and the engine sounds a little loud its done 73 K I have read plenty of posts and many people saying they are loud engines. I put my finger on top of each of the injectors the 2 nearest the cambelt felt very smooth almost silent the two furthest away from the cambelt where very ticky and loud is this an indication that they are worn ? Would this make my engine run slightly rough ? I have seen some spares on ebay so was going to buy some just wondered are do they need coding in ? I have read some post saying some do some dont.
Thanks all for any advice anyone can give.

Regards :mike

Try using some injector cleaner as a one off treatment and then use 2 stroke oil in the fuel, about 200ml to 40 liters, it should make it a bit quieter.

I use it all the time and its noticeable how much louder it is on the occasions I fuel up without using the oil.

I used to use it.....but then ran out, I looked into it and from memory the best stuff was the 2 stroke oil that conforms to JASO-FC spec oil.
