• Use Genuine Silicone RTV Sealant, or equivalent. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".
• Before installation, wipe off the protruding sealant.
• C: 2.6 - 3.6 mm (0.102 - 0.142 in) dia.

Bolt position Bolt diameter 

1, 2: 8 mm (0.31 in) 

3 - 22: 6 mm (0.24 in) 

• Retighten the front timing chain case bolts in the order as shown.

  Bolt position Tightening specification 

  1, 2: 28.5 N.m (2.9 kg-m, 21 ft-lb)

   CAUTION: When replacing seal rings, replace all rings with new ones on both RH and LH IVT control valve covers.
2. To check the joint between dowel pins and dowel pin holes, check the looseness in the axle direction by pushing the circumferential looseness (between dowel pins and dowel holes) by twisting in the circumferential direction.
   • A: Mating surface of magnet retarded
   • B: Moves slightly
   • C: Not shaken
   CAUTION: Always perform this procedure when removing because the gap between dowel pins and dowel pin holes may not be caused on purpose.

3. Install IVT covers with a new gasket to front timing chain case.
   • 1: Valve timing control cover
   • 2: Magnet retarder
     CAUTION:

     • Never face magnet retarder side down to prevent magnet retarder from dropping.
     • Check the mating surface of the magnet retarder and the drum of the exhaust side camshaft sprocket for foreign materials.
     • Align center of both shaft holes of the shaft and the intake side of the intake camshaft sprocket, and then insert them.
     • Be careful not to drop the seal ring from the shaft groove.

     • When setting the valve timing control cover in position by hand, if valve timing control cover is not centered with the valve timing case, the dowel pin of the magnet retarder may not be aligned with the dowel pin holes of the cover. In this case, return to step "b".
4. Being careful not to move seal ring from the installation groove, align the dowel pins on the front timing chain case with the holes to install valve timing control covers.
5. Tighten bolts in the numerical order as shown.

   • A: Bank 1 (Conventional RH bank)
   • B: Bank 2 (Conventional LH bank)
   • C: Dowel pin hole

• Use Genuine Silicone RTV Sealant or equivalent. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".

• Lubricate thread and seat surface of the bolt with new engine oil.
• Apply a paint mark for the second step of angle tightening.

  Step 1: 44 N.m (4.5 kg-m, 32 ft-lb) 

  Step 2: 84° - 90° degrees clockwise
