Odd tick noise

[Tommio RS]

Hi there ZR-1 Registry.


I come today with a question about a noise my 95 ZR-1 has developed.


Back round of my 95 ZR-1 and info on the noise.


The car is totally stock other than the Marc Haibeck chip
and a x brace.
Work that i have done over the years are speedo drive in the transmission, oil pressure sender unit and rebuilt/ replaced the serpentine belt tensioner and the belt and the spark plugs when i 1st got the car. It had a nasty multi cylinder miss fire when at full operation temp. Plus oil changes.




So here is what the car is doing.
Car is warming up or at full operation temp and it will start "tick, tick" randomly? It will still tick with the clutch in or out. If you rev the engine at all over idle i cant hear the tick. This tick NEVER was there before i parked it for winter and now after winter it has this tick? The way it ticks to me its not top end or bottom end maybe its accessory drive or exhaust related?



Video:
The tick happens near the end.
