John. wrote I would suggest improper mating surfaces, gaskets etc. rather than excessive oil pressure. ----------------
John: That may be true. But the work was done by Jabiru. He has built is own design aircraft with a very close fitting cowl, he had to modify the front lower cowl when it returned from Jabiru. To my understanding the pump protruded out further from the engine and made contact with his cowl ??? His earlier problem was trying to get the engine to run hot enough, and low oil pressure, He did not have an oil cooler, but Jabiru insisted that the lack of oil pressure was due to lack of oil Cooler ?????? So he fitted and oil cooler and the temp did not improve As all this is secound hand info. I will try track him down ???
