What do i need to ask??

Paul how big an issue are the injectors if they are a little tappy?

the noisey injectors will piss you off as its so noticeable

also look where the injectors enter the head pools of what look like oil is diesel passing out past the injector seats

this can make removing injectors a bitch also the seat sealing surface area may be damaged so even new copper seals wont seal
