Aloha from Honolulu,
My 62 Eureka Hearse 390 engine was rebuilt about a year ago.
Always had low oil pressure. Cold idle is 27PSI and max 29. Hot is idle 6 PSI and max on the freeway at any speed 21 PSI. Even with 60W and Lucus only about 1 or 2 PSI better.
Oil pump also rebuilt and even pulled the oil pan and put a couple small washers with the new spring. Did not help.
My 59 Coupe De VIlle and 59 Series 62 Convertable both those 390s are rebuilt and have 30PSI cold idle and 32max and hot idle 20PSI and max 28PSI on freeway. They both have a couple washers on oil pump pressure release spring (shim).
Any idea what I can do to up the presure?
Thanks
Ricky
