> 2. Something is up with the hydaulic valve lash adjusters (HVLAs). Started the car up this morning and it's fine now. It clattered like startup clatter for 1-2 seconds and then went away completely and now it sounds perfect. Guess the HVLAs needed to heat up and then cool down again once to fix themselves?
