Component Tests: Weep
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Seep(s): A seep is considered a more pronounced weep but not enough to result in dripping. When wiped off, the moistness should not reoccur before renewed operation. A seep is oil detected under black light inspection and characterized by oil detection under white light inspection resulting in staining at the sealing and the adjacent flange. A seep is not acceptable for fuel, brake or transmission lines, in visible areas under hood or under vehicle. Seeps are acceptable around engine ventilation components such as PCV components and oil fill caps.
