I found the oiling diagram in my Honda factory shop manual. I also found the procedure for testing oil pressure. As usual oil pressure is tested at the port for the oil pressure switch. Spec is 77 PSI +/- 10 PSI at the port at 5000 RPM. When I spoke to David Dodge on Saturday he told me the port was 'metered'. I can only assume that it is because this point is after the main bearings. Still, even on the low side at 67 PSI that should be more than enough pressure to supply the heads. (Has anyone ever measured the oil pressure at the transmission port Honda used?) Also, the 5 - 7 PSI switch point on this switch seems very low to me? Since it is just a 12 volt switch I think it would be a better option to use one in the 12 - 15 PSI range. I still think this oil port is a better place to suply the heads from.
I'm going to plastigauge the bearing surface for the cams tonight.
