2. Unscrew and remove the oil pressure sensor. Remove the oil level dipstick.
3. Disconnect the crankcase ventilation hose from the camshaft cover.
4. Turn off bolts, marking arrangements of suspension brackets, then lift a cover of a head of the block of cylinders and remove a sealant. Loosen the mounting bolts, remove the camshaft sprocket access plate and gasket at the front end of the cylinder head.
5. Rotate the crankshaft until the pointer in the hole on the right side of the cylinder block lines up with the mark on the flywheel/drive plate. In this position, piston No. I (front) set to TDC. The injection timing mark on the camshaft sprocket must align with the notch in the camshaft sprocket base plate and the notch in the camshaft must be correctly positioned to allow full access to the cylinder head bolts (see illustrations). If not, turn the crankshaft a few full turns. Do not rotate the crankshaft/camshaft forward from this position.
6. Remove the plastic side play bolt at the end of the camshaft, then loosen and remove the camshaft sprocket mounting bolts. Remove the sprocket from the camshaft. Check that the camshaft sprocket and drive chain remain properly engaged, secure them together with wire. Make alignment marks between sprocket and chain.
7. Remove the two small bolts securing the drive chain cover to the front of the head.
8. Working in the reverse order shown in illustration 12.19, evenly loosen the cylinder head bolts one half turn at a time until all bolts can be loosened and removed by hand. Discard the bolts; new ones must be used when installing.
9. Raise the cylinder head. Remove the gasket and o-ring from the top of the drive chain cover. Also remove the head location pins.
10. Remove the mounting bolt and washer and remove the pulley assembly from the crankshaft. To prevent rotation when the bolt is loosened, block the flywheel/drive plate with a homemade tool like the one shown in the illustration.
11. Carefully examine the flywheel/drive plate mounting bolts; find the bolt that is marked with a label «R» and mark its position on the flywheel/drive plate (see illustration). Loosen the mounting bolts and remove the flywheel/drive plate. On automatic transmission models, remove the washer and spacer behind the drive plate. Discard the bolts; new ones must be used when installing.
12. Turn off bolts, remove the water pump and a lining from a covering of a driving chain.
13. Unscrew the drive chain tensioner, remove the gasket.
14. Turn the engine over on the workbench.
15. Loosen and remove mounting bolts, remove pan and gasket (And). Note that the bolts are different lengths. Unscrew the inlet pipe from the base of the oil pump, remove the gasket.
16. Turn off bolts of fastening of a covering of a driving chain, bolts of various length. Remove the cover with both gaskets. Remove the location pins.
17. Make alignment marks between the crankshaft sprocket and the drive chain, then disconnect the drive chain and remove it along with the camshaft sprocket.
18. Remove the mounting bracket (s), remove the blades of the drive chain tensioner.
19. Remove the mounting bolt, remove the drive chain guide from the front side of the block. If necessary, unscrew the camshaft sprocket base plate.
20. Mark an arrangement of covers and rods concerning each other.
21. Lay the cylinder block on its side, then unscrew the bolts of the lower head of the connecting rod of cylinder No. 1 and remove the cover. Using a hammer handle, tap the connecting rod and piston through the top of the block. Install the cap onto the connecting rod, keeping the bearing shells in their basic positions.
22. Repeat the procedure with the remaining pistons and connecting rods.
23. Main bearing caps should also be noted.
24. Turn the block over again, then unscrew the bolts of the main bearings and remove the covers. Be careful to keep the bearing shells in their respective caps.
25. Lift the crankshaft out of the crankcase, remove the oil seal. If necessary, remove the oil pump/distributor drive sprockets and drive chain, noting the installation orientation. Remove the segment key from the crankshaft groove.
26. Remove the upper halves of the main bearing shells from the crankcase and place them with their respective caps.
