Re: low volume oil pump
So, you're running a -10% volume pump and what amounts to 0.003" on the mains? What is your clearance on the rods? What oil?

Re: low volume oil pump
That's a lot of oil clearance for a low volume pump, isn't it?
Which rod journals?

Too much clearance for a -10% volume pump. And 15W40 is not really a good oil choice, either. You'll have about 10 psi hot at an idle of 800 RPM. And maybe 50 psi at 6000-7000 RPM.
