Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Separating Parts
Important: Many internal engine components will develop specific wear patterns on their friction surfaces.
When disassembling the engine, internal components MUST be separated, marked, or organized in a way to ensure reinstallation to their original location and position.
Separate, mark, or organize the following components:
- Piston and the piston pin.
- Piston to the specific cylinder bore.
- Piston rings to the piston.
- Connecting rod to the crankshaft journal.
- Connecting rod to the bearing cap A paint stick or etching/engraving type tool are recommended. Stamping the connecting rod or cap near the bearing bore may affect component geometry.
- Crankshaft main and connecting rod bearings.
- Camshaft and valve lifters.
- Valve lifters, lifter guides, pushrods and rocker arm assemblies.
- Valve to the valve guide.
- Valve spring and shim to the cylinder head location.
- Engine block main bearing cap location and direction.
