Occasional exhaust in the passenger compartment

Hi,

One of the most common issues with the 5.4L is a cracked or leaking exhaust manifold. By chance, do you notice a leak or even a ticking sound when you rev the engine?

Also, have you opened the hood to see if you can tell where the smoke is coming from? It could also be an oil leak you smell.

Take a look through this link and then check on your vehicle for any evidence of oil leaks.

Let me know what you find.

Take care,

Joe
