Pre-oiling a SBC
I am getting getting to start up a 327. The engine was started and broken in by the engine builder 6 months ago.
The engine builder said that I should pre-oil the engine prior to start up since I would not be able to install the engine for several months.
I am trying to pre-oil the engine and am using a priming tool from OEM part #27060. I am using a 1/2 inch electric drill to power the tool. The oil pressure shows 50 lbs. on the oil pressure gauge but after three minutes of priming I still do not have oil at the lifters.
Do I need to just keep running the drill for a longer period of time? I have rotated the engine several times and ran the drill at each stopping point.
My assumption is that just because I show pressure on the gauge that merely the indication of pressure is not sufficient and I need to see oil at the lifters.
Any suggestions/recommendations appreciated------Mark
