After engine rebuild, persistent PCV system overpressure may indicate hidden internal porting failure causing crankcase pressure buildup.
No clear guidance or diagnostic tool exists to differentiate between external tubing leaks and internal engine porting failures in PCV systems of modern turbocharged engines.

Workarounds Described
- replaced all external PCV tubing, couplings, and valves manually to troubleshoot
Implied Software Gaps
- Diagnostic tool that pinpoints PCV system fault location without replacing all components
App Concept
PCV Flow Analyzer
A diagnostic tool that combines pressure sensing and flow visualization to rapidly pinpoint PCV system blockages or leaks, distinguishing between external and internal faults. Provides step-by-step guided diagnostics with engine-specific data.
Key Features
- Real-time crankcase pressure logging with historical comparison
- Visual flow indicator for PCV circuit sections
- Engine-specific diagnostic tree (e.g., Ecoboost 3.5L)
- Wireless report sharing with community/forums
Target Users: Independent automotive repair shop owners and DIY mechanics working on modern turbocharged engines.
Revenue Model: $49 one-time hardware dongle + $19/year subscription for database updates and cloud storage
