There's no disagreement here we are only stating our procedures learned over the years! Pumping lifters up is not needed at all. except a couple of aftermarket brands that state to pump them up in their tech sheet! The Chrysler dealers I worked for had warnings about damage to cams ,etc if pumped up, so did Ford! all the main cam company's have warnings in their tech sheets! Its the way I was taught and have taught for years!


Cleaning , and proper lubricating is a much better use of your time. There are so many installers who don't do that most important step CLEANING!!


Soaking in a can of oil is messy and wont fill a lifter only the small cavity above the plunger & below the pushrod seat! you must compress the lifter till it bottoms out and release it to fill it while under the oil in the can, or tear it down fill and reassemble it for those of you that want to fill yours
Bleed down rates vary by design if heavy break in lube or small debree enters the lifter with a slow bleed down rate it can lock the lifter and it wont bleed down! That's why you don't use anything but oil on the lifter bores or the sides of the lifters! Over the years Ive seen them locked up right out of the box and had to tear down and clean them or get a replacement, and some that wont pump up! cheap brands like Su----, J--s, Cr-w, etc Maybe a dozen over 50 years installing cams kits or new lifters!

The last word from me on this is if a tech sheet said don't pump up a lifter I wouldn't say "Hell I'm going to pump it up anyway"! Nor would I say "Hell I'm going to break in my cam at 4000 rpm for 15 min" if a tech sheet say's 2000 for 1/2 hr. because some people say that's all that's needed or wrote a paper on it ,or you watched u tube and saw some videos of people doing it and the car still runs at the end of their home made video

That's my thoughts and my old outdated way (reading and following Tech sheets) of doing things !! If some one can put on here my way is going to in any way cause damage put it on a thread
