Engine explodes after oil change

[ThirdgenTa]

Basically guy came in for an oil change on his impala and when they went to start the car it started on fire. Of course the oil change place is denying any responsibility.
What do you guys think caused it? Slow Chevy, your expertise?

Definetly wasn't the oil drip recall. Looks more like the fuel line burst

it must have loaded up with fuel from a leaking injector or a really bad regulator.
It looks like it blew part of the intake off, that's the only thing that makes sense.

In 20+ years of working on cars I've seen some strange stuff.
Just had a hemi durango that was misfiring for a LONG time. Customer drove it that way. Some people dont care just as long as it still drives.
Then came plate renewal time, = failed emissions.
One of the techs in the shop did a simple repair, got it running correctly.
Customer then requests an oil change, he does it. Upon start up, on the previous misfiring cylinder the piston failed.
It snaped in 2 around the circumference of the piston thru the piston pin bore.
The top of the piston stayed near the top of the bore @ valve lift height.
The bottom followed the rod down the bore & broke @ the bottom of the bore.
Then the rod went thru the block in the side of the bore on the next few revolutions.

Never know what your gonna run into.
