VERY surprised how hard it was to spin the oil pump? I did get oil up through the lifters and through the rockers, but man lots of torque required?
Is this normal? |
Like Bob said, it's normal calls for a 1/2" drive drill. The first time I did it the drill and pump ran for a while before building pressure, then WHAM, hold on tight to the drill. That was a Melling high volume pump on a 460, with 5W30 oil. It typically runs 80 PSI on a cold start fast idle and around 25-30 PSI on a hot idle, so bearing clearances are moderately tight.
