Replacement Part 

Gasket
Quantity: 1
Location of use: Oil filter body
CAUTION:
  • When the transaxle is installed, do not suspend the engine. Otherwise, the SST installation area of the cylinder head may be damaged due to excess weight. Only suspend the engine after separating the engine and transaxle.
  • Applying excessive force (force of 100 N {10.2 kgf, 22.5 lbf} or more) to the electric variable valve timing motor/driver may cause a malfunction. When servicing, be careful not to apply excessive force to the electric variable valve timing motor/driver using other parts or tools.
  1. To enable to install the SST, disconnect the clip shown in the illustration and set the wiring harness aside.
