4.8 ls ticking noise help

[izzy_Britton]

So you did a cam and rebuilt heads but you didn't do lifters for some reason? It is a 100$ job with all the heads removed already... Is there a reason that you didn't do the lifters?

Did you mess with the lifters at all while it was apart? Maybe got one in sideways? Typically lifters make noise when cold, and go away when warm. But I have seen only once in my life, where a roller lifter got stuck sideways and was riding the cam like a good ole non roller lifter and chewed the ever loving crap oitta the cam. It made me noise when warm than cold and I initially thought it was a rod bearing.

Some of the 4.8/5.3s have a little piston skirt slap going on OR wrist pin noise. Not too commoni don't think. But I would set my sights oh lifter noise if you never replaced them.
