Just got a valve job done and the engine is quiet enough for me to hear more noises. Any ideas? Same noise present when belts and fan was off. It also has a fresh short block in it with less than 10k on it.


Update: pulled ps pump and that wasn’t it. It’s a click / tick that doesn’t become louder with higher rpm. When I have the stethoscope on the timing chain cover and upper oil pan I can hear it the most. Oil pump?

Does it change with AC pump activation? If so coukd be bearing in idler pulley.
Edit sorry just read you took belts off and it was still there.
 
Bump! Same noise in my '96 1FZ-FE w/ 210K miles. Have appt with Merriam in a week. Curious to know. Been speculated as flex plate crack or rod bearings by weekend mechanics, but not certain.
