We have come across some bad pressure ratios on a recent leak down test and it seems there is an exhaust leak on the 5 and 6.  The problem is that this is an engine with only 75 hours (hobbs) on it and this does not make sense.  It has been serviced according to Jabiru schedule and we are committed to using AVGAS 100LL.  Engine number is 33A 2841.  Any suggestions?

Low leakdowns at those low hours are unusua, I  suggest contacting Jabiru or their local dealer for advice on this one.
