Tightening torque
PCV valve: 2.5 N·m (0.25 kg-m, 2.0 lbf-ft)

my car at 151km follow the procedure in the service manual and use an injector cleaner spray to clean the PCV valve.everything checks out OK

Interesting... Will definitely be trying this. Do I need any special tools?

just a plier to lose PCV and hose.
be careful not to over tight PCV

car at 193,000km as preventative maintenance, I bought an OE PCV valve with the hose and wanted to replace both but the hose is too hard to pinch at the intake manifold so I didn't risk it just replaced the PCV valve . the part number for PCV value is 18118-78K00 and hose 11192-57L00.
