I've seen the timing chain tensioner cover (across from the water pump cover) and it looks easy to access. Am I wrong? If anyone can tell me if I just have to drain the oil, loosen/remove the drive/ac belts, and remove the tensioner, please confirm. Or do I just follow the FSM? I read the FSM and it only has the timing chain cover disassembly and not just the timing chain tensioner cover. If there is way more to it, then I'd love the feedback.

I've been told it is a bad lifter, but if it was a bad lifter, wouldn't I experience a loss of power? I have zero loss of power, just annoying tick at idle, and the tick increases with rpm increase. Seems pretty common on these G35 coupes as I've read.
