Customer Question
My 2008 DTS recently...

My 2008 DTS recently began leaking a minor amount of oil around the oil pan. The problem went from having no bad fumes entering the car via the AC to where it seems dangerous. When I looked under the hood, I noticed that the hose that goes from the front valve cover to the engine air inlet was disconnected. Could this be related to the oil leak?

Mechanic's Assistant: Have you ever replaced the gaskets? Maybe the hoses?

No

Mechanic's Assistant: Are you fixing your DTS yourself? What have you tried so far?

My dealer verified that there is an oil leak around the pan and that it will cost about $5,500 to $6,000 to fix it.

The oil leak that dealer found is usually low enough where it does not cause a smell. When you can smell oil burning that usually means leak is higher up on the engine which allows oil to contact exhaust manifold which makes the leak. The hose that is disconnected could be the cause so I'd definitely reconnect it. I that doesn't help I suspect your rear valve cover may be leaking allowing the oil to leak onto manifold. My goal is to provide 5 star service so please let me know if you have any questions, thanks.
