Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Component Tests: Weep
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.
