In this episode, we talk through what white, black and blue diesel smoke can tell you—and why smoke colour is only the starting point for a proper diagnosis.

Drawing on three generations of practical diesel experience since 1956, the discussion covers real workshop examples, blow-by, oil consumption, airflow restrictions, carbon build-up and the differences between older mechanical diesels and modern common-rail engines.

Straightforward diesel knowledge from the Berrima Diesel family workshop in Berrima, NSW.
