CAUTION:
During engine repair procedures, cleanliness is extremely important. All parts must be thoroughly cleaned and any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
NOTE:
Assembly of the engine requires various inspections/measurements of the engine components (engine block, crankshaft, connecting rods, pistons and piston rings). These inspections/measurements will aid in determining if the engine components will require replacement. For additional information, refer to ENGINE SYSTEM - GENERAL INFORMATION

NOTE:
This procedure is for selecting bearings using a new crankshaft.
NOTE:
Before assembling the cylinder block, all sealing surfaces must be free of chips, dirt, paint and foreign material. Also, make sure the coolant and oil passages are clear.
CAUTION:
The lower cylinder block must be installed and the bolts tightened within four minutes of applying the sealant.
NOTE:
Clean and degrease both surfaces using metal surface cleaner before applying sealant.
CAUTION:
Fasteners No. 5--8 are studs. Fasteners No. 18--22 are M8 x 1.25 mm x 79.3 mm (0.05 in x 3.12 in) bolts. Fasteners No. 1--4, 17 are M8 x 1.25 mm x 95.3 mm (0.05 in x 3.75 in) bolts. Fasteners 9--12 are M10 x 1.5 mm x 106.8 mm (0.06 in x 4.20 in)/M8 x 1.25 mm x 21.5 mm (0.05 in x 0.84 in) studs. Fasteners 13-16 are M10 x 1.5 mm x 106 mm (0.06 in x 4.17 in) bolts. The bolts and studs must be installed in the correct position or engine damage can result.
CAUTION:
Be sure not to scratch the cylinder wall or crankshaft journal with the connecting rod. Push the piston down until the connecting rod bearing seats on the crankshaft journal.
NOTE:
Lubricate the pistons, piston rings, connecting rod bearings and the entire cylinder bores with clean engine oil.
NOTE:
Make sure the piston rings are positioned to specifications for installation. For additional information, refer to PISTON .
NOTE:
Make sure the piston arrow on top is facing toward the front of the engine.
NOTE:
After installation of each piston and connecting rod, rotate the crankshaft to verify smooth operation.
NOTE:
The rod cap installation must keep the same orientation as marked during disassembly or engine damage may occur.
CAUTION:
The camshaft roller followers must be installed in their original positions.
NOTE:
RH shown, LH similar.
CAUTION:
CAUTION:
NOTE:
Clean the sealing surface with metal surface prep before installing a new press-in-place gasket.
NOTE:
Lubricate the camshaft oil seal with clean engine oil.
NOTE:
Failure to verify correct timing drive component alignment will result in severe engine damage.
NOTE:

CAUTION:
During tensioner compression, do not release the ratchet stem until the tensioner piston is fully bottomed in its bore or damage to the ratchet stem will result.
CAUTION:
Failure to verify correct timing drive component alignment will result in severe engine damage.
CAUTION:
This pulse wheel is used in several different engines. Install the pulse wheel with the keyway in the slot stamped "30" or "30RFF" only (orange in color).
CAUTION:
Only use hand tools when removing or installing the spark plugs, damage can occur to the cylinder head or spark plug.
NOTE:
NOTE:
Apply clean engine oil to the seal lip and seal bore before installing the seal.
NOTE:
NOTE:
Lubricate the outside diameter sealing surfaces with clean engine oil.
NOTE:
Lubricate the new oil pump screen and pickup tube O-ring seal with clean engine oil.
NOTE:
The center coolant pump uses a sealing washer and must be replaced whenever the bolt is removed.
NOTE:
The hole in the coolant pump for the center coolant pump bolt is threaded. Once the center coolant pump is unscrewed from the camshaft, it must also be unscrewed from the coolant pump.
NOTE:
Install a new O-ring seal on the thermostat housing and lubricate with clean engine oil
CAUTION:
Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.
NOTE:
The valve cover must be installed and the bolts and stud bolts tightened within 4 minutes of sealant application.
NOTE:
Install a new gasket in the valve cover.
NOTE:
The valve cover must be installed and the bolts and stud bolts tightened within 4 minutes of sealant application.

NOTE:
Install a new O-ring seal on the oil level indicator tube and lubricate with clean engine oil.
NOTE:
If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
NOTE:
Clean the sealing surfaces with metal surface prep before installing the upper and lower intake manifold.
