Crossover at #1 is to supply driver side lifter gallery via a cam bearing that isn't supplying a main.Forgive my ignorance, but what's the point of this mod if you already have crossover at no.1 cam bearing?
Does it supply more oil to the main bearing? I have done the no.1 bearing crossover, plugged the cam bolt and timing chain oiler, but haven't plugged or reduced flow at 4 where most people tap and bolt up.
#4 cam bearing blockage is to stop bleeding oil to driver gallery when it should be feeding #4 main and rods #6&7
Single pipe mod, aka feed #4 internal mod - basically is just to even up oil pressure along the length of passenger side lifter gallery. The object is for #4&5 to have the same oil pressure available as what #1&2 have.
I don't have hard data, but someone has measured the pressure difference in a running engine front to back and supposedly the results were eye-opening.
Again, I don't know what the numbers were, so am only speculating and repeating what I possibly read a decade ago.
