Broken piston?

I was recently running down the interstate on Vivians tow tune, when I exited I noticed a shudder when the converter was locked at 50mph. I also discovered a very rough idle. I scanned the code. p0272. I assumed #4 injector, I swapped it out with no change, same code too.

So here are my symptoms in a nutshell

1. p0272
2. rough idle
3. when cranking it hits 7 times, then on the 8th it skips, as if one cylinder has no compression.
4. smoke comes out the oil fill cap and dipstick.
5. stinky whiteish gray smoke at idle.

By the way I am getting smoke in the crankcase and the way it cranks over I am thinking a cracked piston. Any ideas?

Manual compression test of suspected cylinder needed to confirm your suspicions.
