DIY mechanic cannot align camshaft timing marks after rotating crankshaft to TDC, unsure if engine is out of time or what caused rocker arm to dislodge, and needs a clear diagnostic procedure.

Workarounds Described

• rotated crankshaft to TDC=0 and found cams behind
• attached pictures to forum for help
• attempted to align color links on chain but could not match

Implied Software Gaps

• Interactive timing verification app that cross-references crank position with cam marks using photos
• Diagnostic tool that explains likely causes of rocker arm dislodgement and timing discrepancies

CamAlign Pro

CamAlign Pro is a mobile diagnostic app for DIY mechanics and small shops that guides step-by-step camshaft timing verification using photos of marks and crankshaft position. It compares user-provided images against a database of engine timing patterns to identify misalignment causes and suggests corrections. Unlike static manuals or forum posts, it provides interactive, engine-specific troubleshooting.
