does not usually happen at idle throttle but I think did happen once turning left at a traffic lights slowly
- happens at low throttles
above 30mph seems to happen at a wider range of throttles
does not happen under load, for example going up a moderate hill top gear (with 3.9 diff) at 45mph
I wondered if this is the start of timing chain rattle and the sound will not sound as bad as the wear increases with it going from more of a clunking to a rattle? It does seem to be under similar conditions to such a rattle before in the previous engine which did not sound the same. Could it also be caused by the ignition being too retarded or vac advance issues? Otherwise, can it be something else?
