Workarounds Described

• Compares chain slack to feel from previous experience
• Posts to Reddit for collective expertise
• Replaces parts (cam bridge) hoping it fixes the issue

Implied Software Gaps

• Diagnostic tool that analyzes engine data to differentiate chain stretch from phaser wear
• Collaborative knowledge base with verified failure patterns and repair outcomes
• Decision support system that guides technicians through targeted tests before replacing parts
