lifter noise??

thats what i need you to tell me...when i started it up we heard a loud noise like a bad lifter..added a qt of oil and noise went away...after cleaning out inside of blower car starts but wasnt firing on left side.. can a bad lifter allow this to happen..the top of the valve looks fine and the spring looks like its all thier...what are your thoughts?
 
u.m. replaced lifter...

runs like a raped ape,, thier is a slight tick but IMO its quieter than new...

hope the valve is ok ,,,,,,but if it was bent or not fully seating should thier be noises like a bad lifter??

thanks for all your help here U.M.
