Engine Parts and Gasket Installation and Assembly Guide

1. Preparation: After the engine has cooled, disconnect the negative terminal of the battery. Clean your workspace and prepare the necessary tool sets.

2. Removal of Old Parts: Remove the air intake pipe, valve cover, manifold, and thermostat, and take out the old gaskets. Remove the oil pan to access the oil pump and main bearings. Loosen and lift the cylinder head nuts.

3. Surface Cleaning: Clean all surfaces with solvent and a plastic spatula; remove dust and residues.

4. Installation of New Parts:

   • Piston and ring set → with a special tool for the cylinder bore.

   • Crankshaft and bearings → place in the oil bearing housing and tighten the caps according to the torque table.

   • Timing chain set → align with the gears, secure the tensioner and rails.

   • Valve seal & spring set → to the valve shaft and seal housing.

   • Cylinder head gasket → place the head, apply torque with a step tightening method.

   • Manifold gaskets → torque the flange nuts.

   • Oil pump & water pump → gasket and nut torque.

5. Filling & Testing: Fill the cooling system with antifreeze and bleed; change engine oil and filter; start the engine and monitor oil pressure and cooling temperature; check valve and chain noise with a test drive.

Maintenance and Longevity Tips

• Check valve clearances and oil leak points every 30,000 km.

• Measure timing chain tension annually.

• Use manufacturer-approved engine oil and antifreeze; avoid low-quality additives.

• Clean mounting surfaces during each revision; smooth contact increases sealing.

• Absolutely adhere to manufacturer torque tables with your torque wrench; meticulously apply the cross-tightening method.
