Engine

2 reports1 fire
“The vacuum pump (Porsche part number 9A1-110-090-02) cover retaining screws vibrated out causing the cover to damage the fuel lines and causing an engine oil leak. The fuel and oil were ignited by the exhaust or stray spark cause by the vacuum covers rotation and hitting other metal objects. This vacuum pump provides vacuum to the brake booster and during the event drastically reduces the ability of the car to stop. The car was quickly consumed by fire (30-45 seconds) and I received very minor burns to my left arm exiting the car (mid-engine so the flames were coming out from under the drives side rear tire). I no longer have the car or parts but do have a lot of photos of the damage”
