the engine starts up right away and i used a heat gun on the engine .
i actually had to use my heat gun to start it up since it was sitting for while.
I have a feeling the slop you are talking about is the rocking motion you will get when you put the piston at TDC. If you still have a slight amount of pinch when the engine is cold and the piston gets slightly stuck at TDC you will notice you can turn the flywheel slightly and the crank pin location may move from 11 o'clock to 1 o'clock when looking in the backplate opening.
If your rod is indeed bad you will notice you are killing glowplugs and the engine is flaming out. If it was running fine and was not killing plugs you should be fine. I have that same play you refer to in most all of my engines. If you always heated your engine I bet the rod is fine.
