I have a 2200 Jabiru which I have rebuilt and even though some query emails are slow for response times, the data supplied has been very informative. The oil pump has had several service letters published regarding the oil pump plate and possible cavitation of the oil pump at low tempretures. Jabiru have supplied replacement plates at no cost except postage (exchange). It may be possible the modified plate is thicker but even so...that is a very fine tolerance with the pump to cowl. Yes Jabiru insist on an oil cooler. I believe all Jab engines now require an oil cooler. Oil pressure cannot be maintained with overheated oil. Maybe an airflow issue on the above setup. Don't forget the engine by design is very young and any teething problems are being ironed out. Stand by our aussie mates....it will happen!!!
