Hydraulic lifter preload

Hey guys ..
I have a short video of engine tick I'm talking about.
This is after engine is brought to operating temperature . Upon initial start there is very little noise.
I drove the car tonight and it has no lack of power.
I hope to pull the valve covers and have a peek this weekend.
I'm running 10 w 30, I can confirm oil pressure tomorrow but pretty sure it's
10- 12 psi when warm at idle
Thanks for any advice
