  1. Apply silicone sealant to the engine front cover as shown. (Scheme 428): Applying Silicone Sealant To Engine Front Cover Thickness 2.2-3.2 mm {0.09-0.12 in} 1.5-2.5 mm {0.06-0.098 in} 2.2-4.3 mm {0.09-0.16 in} 3.3-4.3 mm {0.13-0.16 in}
  2. Install the cylinder head cover bolts in the order as shown in the figure. No. Tightening torque 1-18 8.0-11.5 N.m {81.6-117.2 kgf.cm, 70.9- 101.7 in.lbf} 19-22 40-55 N.m {4.1-5.6 kgf.m, 30-40 ft.lbf} (Scheme 429): Identifying Cylinder Head Cover Bolts Installation Order

  1. Install the SST to the camshaft as shown in the figure.
  2. Verify that No.1 cylinder is at TDC of the compression stroke. (Position counterweight contacts SST.) (Scheme 430): Installing SST To Camshaft
  3. To position the crankshaft pulley, temporarily tighten it and, using a suitable bolt (M6 X 1.0), fix the crankshaft pulley to the engine front cover. (Scheme 431): Identifying SST (303-507) And Bolt (M6 X 1.0)
  4. Install the SST to the ring gear to lock the crankshaft against rotation.
  5. Tighten the crankshaft pulley lock bolt in the order shown in the following two steps using the SST (49 D032 316). Tightening procedure 96-104 N.m {9.8-10 kgf.m, 71-76 ft.lbf} 87-93° (Scheme 432): Identifying SST On Ring Gear To Lock Crankshaft Against Rotation
  6. Remove the bolt (M6 X 1.0) installed to the crankshaft pulley.
  7. Remove the SST from the camshaft.
  8. Remove the SST from the cylinder block lower blind plug hole.
  9. Remove the SST from the ring gear.
  10. Rotate the crankshaft clockwise two turns and inspect the valve timing. If not aligned, loosen the crankshaft pulley lock bolt and repeat from Step 1.
  11. Install the cylinder block lower blind plug. Tightening torque 18-22 N.m {1.9-2.2 kgf.m, 14-16 ft.lbf} (Scheme 433): Identifying Cylinder Block Lower Blind Plug
