Priming the engine via the oil pump is an absolute must for any smart engine builder and also ensures oil to all engine parts including lifters. I don't however see how a spring change would come into play if the springs were adequate to begin with. I wanted to post this question because as you all know if you ask 25 people A mechanical question you will get 26 different opinions. Thanks again!
The lifters can be dipped into a container of oil but unless the manufacturer's instructions tell you otherwise, there's no need to pump the lifters up before installing them.
There are some exceptions to this. For instance Rhodes lifters DO recommend their "original
" lifters be pumped up prior to installing and adjusting them to 3/4 of a turn, or so the lifter cup is about 1/16" below the retainer.
BTW, was this thread in reference to another thread?
