Can someone please link the “valve lash adjuster procedure” to this post. I tried searching for it, but could not find it. Thanks!!
What procedure do you want exactly? 2010 Prius valve lash adjusts itself. Are you thinking you have a bad adjuster? If so, you just replace it, but I don't know if I've ever heard of one going bad. If you have to replace it, you're looking for the valve train disassembly/reassembly procedure from the repair manual (more info).
N/m. I found it. https://attachments.priuschat.com/attachment-files/2021/03/203171_2010_Toyota_Prius_Repair_Manual_-_Cylinder_Head.pdf
That’s a cylinder head removal instruction lol. 3rd gen Prius has automatic, hydraulic adjustment, using oil pressure. Coming from years of Hondas, I used to do the adjustment, but with 3rd gen Prius no adjustment is needed, or possible.
There is a procedure for testing the adjusters, involving immersing them in oil, and a skinny tool to poke the check ball. It's included in the cylinder head overhaul instructions. Presumably anybody who is looking for that procedure already has the valve train apart on a bench.
