If I were you I wouldnt start it again until you find the problem! If its a collapsed lifter(most likely) its an expensive repair.
The increased lash that fast tells me something broke and if its the roller wheel kiss your cam byebye as whats left of the lifter will chew it in half
and all that hardened steel shavings can do some damage.
Lift your intake and pull the offending lifter pair and let us know your findings and I hope im wrong but I agree with 42 PHASE3!!
What brand lifters are you using?
