Hydraulic lifters soak or not soak ?

Hi guys

A lot of videos on Youtube says, that it is important to bleed the hydraulic lifters in oil until no airbobbels come out and the piston is stone hard.
But on this video the guy says, that it's a bad idea. Much better to let the oilpressure from the engine pump up the lifters:

What is your opinion ?

Regards

I tore down my engine completely a few months ago (there's a very long thread) and I skipped that part as was done in roach's vids. Count me in the No camp. I did plenty of priming of course later. almost 3k miles later - no issues. I do have a slight tick from the top end that may or may not be lifter noise after my wolfie DIY mcct upgrade post rebuild.

Another member and respected pro. mechanic on here I trust advised I didn't have to soak\bleed in my scenario. Yes I had them removed, upside down etc., before reassembly. YMMV

If I can split a case and make it work - you can too!

I think flushing them was the point Roach made.
You flush them with kerosene to clean them out, but I don't recall him pumping oil into them before install....but I could be wrong.
