Oil leak near radiator mount?

Hello,

There is a small leak near the radiator mount on the driver's side. It looks like oil, and it makes a small to medium size spot on the ground after sitting for serval hours.

There is some vibration in the engine when the car is idling in traffic, not sure if this contributes to this.

The radiator was changed earlier this year. No overheating issues at all, the leak seems to be intermittent. Maybe a seal that "shrinks" when the engine is cool, I guess.


Any advice would be a great help.

Thanks, Roosevelt.
