Gasket coating chipping off during cleaning

When a gasket's thin coating starts flaking off during cleaning, it raises concerns about whether moisture will leak through. While some minor wear might be manageable, pinched or damaged gaskets often allow water to sneak in over time and cause rust, meaning they need to be popped off and reseat.

    Cut out a soda can to shape and block off the valve
  4. 4
    Taking the vehicle back to the shop that performed the repair
  5. 5
    Trying to shimmy the seal back in using a screwdriver and a hammer
  6. 6
    Removing the cover and manually popping off and reseating the handle and gasket
