This is the second occurrence of "rodent" damage eating engine wires. The first incident cost me $2,000. This has now occurred again. There is something "maybe soy based" or environmentally friendly materials that are attracting rats, and mice to cause engine damage by eating essential wiring and sensors, causing a fire risk, and highway safety risk.
Cam tower is leaking oil. I was told by the dealership that the oil is dripping onto the exhaust and could cause a fire! The truck is five years old with only 35000 miles on it! Apparently the sealant that is supposed to hold the cam tower together can start leaking oil! But I didn't expect it to leak with this new of a truck and this low of miles! I got on line and apparently this is happening quite a bite on tundras!
