Re: Packard TSB 56T-20 - Low Oil Pressure

Jack. Point #1 u indicate above mite be due to oil gallery diameter too small. I don't know. How does the Packard V8 oil gallery diameter compare to SBC's or other proven engines?????? I'll try to check and SBC tomorrow.

OR, maybe Packard skimped on the main bearing material???

The oil gallery feeding the mains intersects with the main longitudunal oil gallery feeding the lifters. Have u checked the end of the gallery directly where it enters the main longitudinal oil gallery to see if there is any drill burr or other restriction in that area???

That is to say, maybe the drill did not make it all the way thru, only the tip of the drill made it thru thus causing a restriction??
