It is one of those "in a perfect world" scenario's ?
Invariably, yes... the lube wipes off with just residual left behind, which is hopefully enough until it gets running and splash lube, etc., can take over.
just me,
but IMO, V/Spring pressure is what kills Flat tappet Cam run-ins more than the EP additives.
And keeping it well below 300#,(260-280# if you can) over the nose for run-in goes a long way to insuring a patent lobe establishment.... then AFTER break-in.... re-install inners ? whatever ? back to running V/Spring pressure.
If no inners to remove.... low ratio rockers for run-in ? +.060" retainers and leave the Spring shims out ? ANYTHING to get it DOWN !
