I've been looing everywhere on the web (including service manuals), I can't seem to find a torque specs for an 08 Impreza 2.5i PCV valve. Please post here, I'm sure a lot of folks would appreciate it. Thank you

 

The PCV valve for the US EJ253 (SOHC) is the same as that listed for the European EJ204 and EJ154 (DOHC) engines

P/N 11810AA100

Both appear to screw into the block area rather than the inlet manifold.

US Arrangement


European Arrangement


As listed in the European manual
Tightening torque: 23 N·m (2.3 kgf-m, 17.0 ft-lb)

 

Thank you so much!
