Installation Guidelines
Critical Installation Requirements:
  • Always verify correct timing marks alignment to prevent valve-to-piston contact
  • Lubricate cam lobes and journals with assembly lube or clean engine oil before installation
  • Replace camshaft bearings and inspect lifters during camshaft replacement
  • Inspect and replace camshaft bushings if worn to prevent non-rotational movement
  • Follow factory torque specifications and tightening sequences for bearing cap bolts
  • Rotate engine manually after installation to ensure no binding occurs
  • Professional installation recommended due to precision alignment requirements
Warning: Never operate the engine without verifying proper valve timing after camshaft replacement. Incorrect timing can result in catastrophic engine failure.
