I have an 03 Escape with 93K, been a great car, never had any issues. I now notice a rubber type odor coming from the engine. I've checked all the hoses, they apear fine, the coolant level looks good. Could it be something electrical going bad? And now at the same time, I notice a small oil leak under the oil pan, very small, maybe one drop a day in the driveway. Any help would be great.
