Manifold/header/muffler/tail Pipe problems of the 2008 Toyota Sequoia

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 additional 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.

After 4,399 mi. The left exhaust manifold cracked and produced a ticking sound on acceleration and exhaust fumes can be smelled through the vents when fan is on. As per dealers advice, it's ok to use vehicle pending repair. It's been 5 days and the part hasn't arrived yet. Contacted dealer few times to facilitate repair.
