Oil on your oil filter can be caused by damage to the filter's outer housing.
Understanding the Cause of Oil on Your Oil Filter
Typically, oil on the exterior of your oil filter indicates an issue with the filter itself or its immediate surroundings. Here’s a breakdown of possible reasons, as suggested by the reference material:
Damaged Oil Filter Housing
- Physical Damage: As the provided reference suggests, a rock, stone, or road debris can puncture the oil filter's outer housing. This is a common cause of oil leaks and could be the reason you see oil on your filter.
- This type of damage can lead to oil leaking or even spurting out from the filter.
- The oil leak may be intermittent, depending on the severity of the damage and the engine's operating conditions.
- Consequences: If you observe oil spurting from the filter, it is crucial to turn off the engine immediately and call for a tow. Operating your vehicle with a damaged oil filter can lead to significant engine damage due to oil loss.
Actions to Take
| Issue | Action |
|---|---|
| Oil spurting from the filter | Turn off the engine immediately and call for a tow. |
| Presence of oil on the filter | Inspect the filter closely for damage or signs of leakage. |
What to look for
- Visible Punctures: Carefully examine the filter housing for any holes, dents, or signs of impact.
- Oil Leaks: Check for active oil leaks coming from the filter, which indicate a breach in the system.
- Oil Spray Pattern: Examine the area around the filter for an oil spray pattern, which can help determine the source of the leak.
