I have a distinct knocking sound coming from a cylinder at idle. The car is a C250TD P Reg. I have just replaced the injectors and glow plugs and the car starts and runs well; the knocking seems to disappear when the revs increase but reappear at idle. The knocking was there before I changed the injectors but not as noticeable as now.
I listened to the noise by putting my ear to a screwdriver on top of the injector and heard a distinct "ting ting ting" from number 2 cyclinder and a faint ting in number 1. All the rest had the usual wooshing sort of noise and seem to function fine.
Is this a timing issue?
Thanks
Phil
