Switched out a PURE ONE Filter for an OEM on my Mazda3 2.3 & the valve clatter went away.
Had switched to PO 2 OC ago ~14k miles.
Clatter started in all temps upon startup even sitting in 100 degrees asphalt.
Have always used PP & QSHP for brief period of time - latter which I though was the culprit. But this past oil change I could only change the oil (PP) due to time limitation & had to change filter a bit later (following weekend).
Noise went away. OEM did the trick.
I am surprised since PO always has had an excellent rep.
