Default Your predictions Blown engine

Did a full power burnout on a cold engine with 12lbs of boost on a stock engine.
Guess what I damaged a cylinder.
This engine has been replaced and sits on a engine stand. before I pull the heads ect, any predictions what we will find?

But it could be worse.

Lord. not this thing still runs decent the plugs even still look good- but its low on compression 1 cylinder, There is smoke pumping out the oil-fill cap when removed. Putting that new shortblock in was a Mf-er
I forgot to attatch the oil fill tube for tansmission then had to relift the motor to get it installed, then forgot to attatch the coil wire on the opti- (try that once) Had to repull blower, water pump and then a cracked to the plug in for the wire on the opti so ofcourse had to pull the Superdampner and replace the opti. All this while engine was IN CAR.
Had this motor sitting on an engine stand and already had all this off.
Anyway the engine is in and purrs now,,,

Low compression you say?
I guess broken piston ring(s). Forced induction engines require a different ring gap than do NA engines. The wrong gap will cause the rings to buckle and break and damage the piston and gouge the cylinder wall... and all other sorts of mayhem... and all just because of the wrong ring gap.

Why? What were you looking to do with a full on burn out on a cold engine?
Were you looking to wreck the engine?

Quick turn around. Don't you wish just once you could watch the engineer who designed all that actually try and work on it ?
