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.
