Purpose
This site provides calm, general informational content for a common situation: an engine sounding worse (or simply different) after maintenance.
The goal is recognition, urgency clarity, and neutral communication — without panic, and without teaching actions.
What this site does not do
This site does not provide mechanical advice, troubleshooting steps, repair guidance, diagnostic conclusions, or guarantees. It does not replace qualified professional inspection.
If you believe safe operation may be affected, use your best judgment and seek appropriate help.
How to use the pages
Start with the Home page for recognition and calm framing. Use the Urgency page if you are unsure whether the situation may affect safe operation. Use the remaining pages for high-level context and neutral handoff wording if you need to describe the situation to a professional.
