Hello. I have a problem knocking in my focus mk1 1.8tdci around the timing. It does not always occur but in 90% of the time. I hear only at low speed, it seems to me that when crushing stops and when turning up the speed. After unscrewing the oil plug, it does not intensify and it can be heard more clearly from the bottom of the engine. Maybe someone had a similar sound and solved the puzzle?
