Rhythmic ticking sound

[gentilepiano]

Thermostat fits nice and snug, o ring is new also!?!?

Just take it out...and set it off to the side. Bolt things back up without the t-stat in and see if it ticks.

Just because it fits nice and snug doesn't eliminate the thermostat.

Update on the ticking
T Stat removed
new heater control valve
adjusted valves (very quiet)
fan belt off
still a rhythmic click
The clicking seems louder with the T Stat out.
Could it be the timing chain tensioner?
If I remove the oilpan can i get a look at the timing chain??
Could the main bearing cap be loose ?
Thanks All

If you remove the timing cover, you'll be able to see the timing chain.
