Could oil pressure in the lifter bore slow the 'leakage' some? I always assumed that the leakdown came out of the fill hole in the exterior shell? If the leakage occurs on top of the lifter, oil pressure should have no effect at all. In any case, any possible effect of a higher pressure pump would be a small amount, so basically little to no effect, and at 2400 rpm , rhoads will already be moving too fast to lose much lift.
