I noticed a few drop of oil (daily), left side closer to the front of the car.
Looks like a wire hareness going in the engine...can I easily fix this myself? What is the part called? Expensive?? Thanks!!

 

Camshaft position sensor.

Provided the sensor housing is in good shape, a simple O-ring replacement should address your oil seep.

Simple and cheap fix

 

+1 on the camshaft sensor. Easy job. O rings are dirt cheap.
