Pat (CAmachinist) has given me some suggestions regarding my oil pressure concerns on SWMBO's new '66-289-2V. Hot idle is running slightly below 20 PSI. He mentioned "loose lifters" a possibility, then left town on a well deserved vacation. Does he mean the fit in the block or the adjustment at the rocker. Would either or both cause the low idle presssure. Above about 1300 RPM it is over 40. The oil pump is a standard Melling - Not HV.Thanks for the input.
