| Tl- the contact owns a 2008 toyota sequoia. the contact stated that he took the vehicle to a dealer for service in march 2010, and afterwards a friend told him the vehicle was leaking oil. the owner inspected the vehicle and saw the oil leak. the vehicle was taken to the dealer and they stated they could not find the leak. the vehicle was taken to the dealer again and they stated they had found the leak and repaired it by replacing the 0-ring. the failure stopped for a while but returned after a few days. toyota was also notified and they stated the owner may want to take the vehicle to another dealer. the vehicle has not been repaired. the failure and current mileage is approximately 10,000. rd | |||

| Engine oil seepage (or slow leak) at the cam housing and engine head connection (gasket seam) area, above the exhaust manifold, on the right-hand-side engine cylinder bank. oil first detected at 9,000 miles (vehicle was purchased new). concern: possible engine fire if the oil seepage becomes worse over the course of addtional miles driven. oil seepage should not occur in an engine this new - especially in areas near a hot exhaust manifold. other similar toyota v8 engines appear clean at the same area - no oil residue apparent in other toyota v8 5.7l engines of similar specifications. this appears to be a material surface manufacturing defect in my vehicle's engine. engine info: toyota 5.7l v8 corrective action: i took the vehicle to toyota dealer to repair the seepage or leak to avoid a possible engine fire (as a preventive measure), and dealer told me i had to call toyota. i called the toyota customer experience center 1-800 number and the recording stated i was not able to speak to a toyota representative and i should call back later. i have not been happy with toyota's customer service. when i asked a service manager at a dealer about getting this repair done under warranty, he responded by saying i can't do that to toyota. it is unfortunate that toyota values itself more than it values customers. | |||
