Valve lashed X2/ replaced oem TCT 148k loud tick!!!
I bought the car and it needed a valve lash that was audible slightly. I was accelerating up to speed on a on ramp (85-90mph) and a distinct louder tick started. So I kept the revs down and detoured back home the 25min commute. Waited till morning and inspected valve train and valve lashed. Noticed it was still distinct afterwards and waited till new tct arrived. Lashed again. (.08/.010) installed new tct and it’s still doing it. I let it get to operating temp and went on a small drive but it’s still there. Not as dominant with new tct but definitely audible. Attached is video. Should I lash again? Anything else to check for? Was going to boroscope and check to see if bent valves or something. Next I was going to replace valve springs and new timing chain/assembly

Piston slap? What happens when you rev the engine?

Did the measured valve lash change when you did it the 2nd time? Was it way off the 1st time?
There's got to be a reason you're considering doing the valve adjustment a 3rd time instead of moving on to a different solution. Are you not confident in your result or are you questioning your method?
What is the condition of the oil? Any metal flakes?
Is the heathe-to-engine block strap broken? Are your motor mounts broken?
What else have you checked besides valve lash?

If the noise changes or becomes quieter with engine rev, it could be piston slap.
Is the noise more apparent or different when the engine is cold versus hot?

-definitely not tct
-if it was valve lash, you would have had to screw up real bad (a valve set to .020 or more)
-sounds like a low end knock. That is not normal, and not piston slap.

all the noise is up above though that’s what I don’t understand it’s in the valve train. It doesn’t stall on its face
