156 /2.4 Knocking sound ????
i'm new at this forum ...
i own a 156 '98 2.4 diesel with at this moment 210.000 km on the clock.
especially when the engine is warm it gives of a loud mechanical "knockin" sound ... the aux belt has been changed
including all rolls belonging to this belt ... no change.
the latest theory my workshop has is that this is a chain driving the oil pump ... however to change this the engine needs to come out ! and not even the local alfa dealer will start at this job (they tell me).
is there anybody having this problem ? and having the solution ?
