So got a new manuka oil pressure gauge put into my hitatchi digger today. The one with capillary tube.
Is has an Isuzu 4bd1 turbo engine in it. It read the following pressures. At start up it was about 40 psi. Then worked it for an hour to get it hot. When left idling at working temperature it was dropping down to 15 psi. Rev it up and work it was about 30 psi.
Are these sounding low? Engine starts first click and no excess blow or anything from the breather.
