I'm finally getting to starting up the C123 motor in my 240U that I rebuilt. Block was tanked clean, new sleeves, pistons, etc. Rocker arm was disassembled, and rodded out and cleaned. So passages should be clean. Oil pump looked fine: I sanded flat the bottom plate & replaced gasket. Oh yeah, I almost forgot: I replaced all rod and main bearings too.
I want to be sure the oil circulation is OK before firing it up. Cranking it (without starting it), I'm not seeing any appreciable oil up on the rocker arm. Which is my concern. Is that normal? I opened the oil pressure gauge port, and oil flows from there when cranking. I connected an accurate gauge to the port, and it goes up to 10 psi when cranking. So I assume it's priming OK. I read it's supposed to go to 45 psi when it's actually running. . . so far I'm only cranking it.
This is my first major rebuild, so don't know if what I'm seeing is a problem, or not. Appreciate your advice.
