Greetings - '08 Toyota Matrix, 1zzfe 1.8L with startup clatter until oil pressure is established. I found one of the four vanes of the actuator internal moving core snapped clean off and lodged in sideways. What causes this? Should I be looking upstream for something that makes this happen?
FWIW I had the Technical Service Bulletin part/work done on my 09 Matrix - perhaps it would work on yours? https://www.tsbsearch.com/Toyota/T-SB-0087-09
