Sorry Phil
Makes no sense to me.
Maximium oil pressure is determined by the regulator setting not the pump
although a higher volume pump might improve things at idle at pressures
below that set by the regulator. I can't see how a larger pump would affect
the cowl design given its location on the engine. Excess oil pressure
doesn't lead to leaks since the pressure galleries are internal. There might
be some pressure leakage around the oil filter gasket and this is normally
the thing that blows first if a regulator is set too high. In extreme cases
the oil cooler might split but I've not heard of this in the Jabiru. The
rest of the engine joints are mainly subject to sump pressure which might be
affected by blowback or a blocked breather but not oil pressure. If the
joints are leaking, I would suggest improper mating surfaces, gaskets etc.
rather than excessive oil pressure.
Jabiru did have some earlier problems with lack of oil supply to the top end
of the engine in tail draggers and steep climbs and with crank deflection in
the early 6 cylinder models. To my knowledge, the company never denied this,
provided good backup and the problems, as Barry says, are seemingly fixed.
If it weren't for the cost I would jump at these donks.
Could you provide more detail please and ask your friend if he has adjusted
his regulator.
