Ticking Noise
 

Hey everyone. So my ‘13 370Z with 42k miles, is now ticking. I haven’t driven it nor started it since February. I finally got it started after a hard hesitation to turn it over, and it began ticking pretty loud (loud to me at least). Did the oil change this past Saturday and started it. Ticking was there, got it up to operating temperature and at 140 oil temp, still ticking. Revved it slightly and it began to tick faster/louder. Once it got to 180 oil temp, it completely went away. Revved it to 4K and it sounded beautiful. Didn’t drive it, let it sit overnight and started it last night and it began ticking but this time, not as violent sounding. Got it up to 180 and disappeared. Do I have a bad lifter? Any input here? I have no Check Engine Light or Codes. Please help!

Oil level is good I assume. Could be something sticking maybe run some fuel/ upper cyl cleaner through it?

Yes oil level is perfect. I was thinking of taking it out for a little cruise and see if it'll "circulate". I've been told to use an additive/cleaner, dumping some in the engine however I'm unsure of which one to use and would I need to change my oil again if I do use it.

Maybe run some lucas or redline complete fuel system cleaner
