Fresh engine, wiped cam? Tick? (new pics added)

I can make dry lifters do it or a lifter that has bleed down......they have to have oil in the to stay "pumped up" if you had a bad "collapsed" lifter....it will not hold the oil pressure in the lifter and will not let it pump up and maintain pressure.

A good lifter will not rattle by hand and the lifter cup will always be held up against the circlip or snap ring by the internal spring. If not, the lifter spring has been collapsed by too much pre-load. No, they don't have to be pumped up to eliminate a rattle heard by hand. I know how hydaulic lifters work. I changed out my first cam in '82 and was a professional mechanic from 84 to 95.
