Too much exhaust, what may be wrong with my Dodge

[Rich Vernetti]

My Dodge is suddenly running very rough and a lot of exhaust is pouring out the back. The car cant be driven this way, what might be the problem? Is the engine shot? It’s a 2008 Dodge Durango with Hemi Engine.

Is that steam or burning oil?
If it is steam, it’s most likely:
A blown head gasket
Warped head or block or both
Damaged head
Damaged block
If it is burning oil:
Bad valve seal
Damaged piston ring(s)
Faulty PCV
Blown gasket
Your going to have to do some diagnosing.
Check for CEL codes
Compression test on all cylinders.
Leak down test all cylinders.

thank you. How do I know if its steam or burning oil? It smells like exhaust.

Steam usually dissipates pretty quickly. Look at a pot of boiling water
Burning oil is usually thick and hangs around a longer time
