Blown cylinders in 2001 Plymouth Neon - Edited 8/24

My daughter has a 2001 Plymouth Neon LX 2.0L L4 SOHC SMPI 16V with approximately 332K on it. The car blew two cylinders yesterday and I am trying to figure out whether it is practicle to have the repair done. Can anyone help me with approximate cost on this repair and what is involved?

Thanks for you advice in advance.

Additional Info: Not really sure what blew exactly---what I do know is that the car has been pouring smoke especially when first starting---she was driving down the road and heard a loud pop, the car slowed down to a putter and shortly quit on her. When I opened the hood the middle two spark plug enclosures were popped up out of the block and oil was coming out of the engine at a brisk rate.
