Why this site exists
OBS Ford knowledge is scattered across forums, dying Facebook groups, dead Photobucket links and threads that fade into the void. The good answers exist — they're just buried. This site makes the good answer the default: one clean page per question, with the spec, the fix, the video, and the threads — sourced and dated.
The trust model
- Every number carries a source and a status. Right now values are marked community-standard — pulled from forum consensus and public references. Each is being verified against factory service literature (that pass is in progress; nothing is published as verified until it is).
- Nothing is gospel. If a value is wrong, the correction button on every spec sends it back to us, and we fix the record — not just the page.
- Read-only launch. No accounts, no forums, no noise. You come for a number; you get the number.
The research behind the rankings
The problem pages aren't guesses. We counted ~276,000 real forum thread titles across BroncoZone, FullSizeBronco, OilBurners and Ford-Trucks.com, plus 8,574 NHTSA complaints for 92-97 F-150/F-250/F-350/Bronco. The question ledger ranks what owners actually ask, and the content follows demand — the top problems here are the top problems out there.
Corrections
Every spec block has a ✎ fix button (opens a prefilled email to corrections@sejje.net). Tell us what's wrong and what's right — with a source if you have one. Corrections flow into the ledger, get verified, and update the site.
