presoaking lifters
I have always put them in a coffee can and poured oil in the can over night and let them soak.
By the time i run the engine I would have turned the engine over by hand so many times with them installed, nice and slow, they just bleed down.
If i was running minimum valve clearance then maby i would not soak them.
I can't really say that it matters, unless you install them and don't crank the engine over by hand and just start the engine like a fool,then i guess it might be a bad idea to soak them.
