lifter galley crossover tube

Jim...Im going to run an Accusump with the oil supply coming from a sandwich adaptor between the block and oil filter.

Ill place a T in that supply line, run it thru the rear china wall with a bulkhead adaptor, and run a #6 AN line to the front of the rightside lifter gallery then drill and tap for a 1/4” x #6 AN fitting.

I think the #6 should add enough oil flow to thr #1 main bearing to keep it alive.

I will also use King fully groove coated bearings.

That won’t fix the oil timing issue. It’s not that there isn’t any oil there at the rods, it’s that the oil isn’t there at the right TIME.

This is easily proven by the fact the rod bearings look like crap, but the mains are perfect. The oil is at the mains. It’s at the rods. It’s just there at the wrong time.


RPM makes the timing issue more pronounced. That’s why full groove bearing help. To a point. They get oil to the rods all the time, but still not at the right time. As RPM goes up, the time to get full pressure, full flow oil to the rods goes down.

That’s why at lower RPM there isn’t much of an issue. The oil hole in the crank spends more time (albeit it’s measured in .xxxxxx seconds) lined up with the feed hole in the block. As RPM goes up, this time is much less and it becomes a bigger problem.
