3rd cylinder dead- need new engine

The codes read all cylinders were misfiring and the fuel pressure regulator had a problem. I replaced spark plugs, coil packs, and fuel pump regulator. Vehicle still wouldn't start up. Took it to the dealer to check further. They performed a compression test to rule out timing chain issues and determined the rear catalytic converter was completely clogged. The dealer replaced the rear catalytic converter and changed the oil and filter. I paid $1300 for the repair, pulled out of the parking lot and made it 1/4 mile down the road, smoke starts rolling out from under the hood. I drove back to the dealership and they told me the 3rd cylinder is dead and I need a new engine. Before the initial work I had done to the car the engine performed fine. How did the engine blow?

Re: 3rd cylinder dead- need new engine

Your Enclave needs another dealer, sounds to me like. How is it dead? No compression? No spark? Blown piston? Thrown rod? If that's all they're telling you, they're getting ready to take you for a ride

"determined the rear catalytic converter was completely clogged."
The engine probably had raw fuel going into cats for it to completely clog. How long did you drive with with those cylinders misfiring? Any Flashing CEL?
Back pressure from the clogged cat probably caused the cylinder to fail.

Yes, they have completely taken me for a ride! They said that the 3rd cylinder was filled with oil and and I would need a new engine. That is all they said.

^ This is what I was thinking. My guess is the extra heat/pressure from the clogged cat caused the head gasket to fail which caused lubrication or cooling issues for cyl 3. Lost a head gasket to an 85 Fiero back when I was in college in a 2.8 V6 because of a clogged cat.
