Hold up! Am i missing something here? My mechanical english is not too good, so what you exactly mean by lifters i don't know. But you are talking about getting 'the click' from an engine... My engine runs fine, oil pressure great, boost is fine as well, but my car does make a kind of clicky noise. It gets a bit less after driving, but it still is there. I always thought the noise was just the injectors spraying fuel.... Or is it something else?
If not, i'm very sorry i once again used up some of your time with a 'stupid' question
