Just tore apart my motor....
At first glance this $100 5.0 looked to be in decent shape
I pull the upper manifold off and there is "chocolate milk" in the #8 runner
So I soak up as much as I can before removing the lower. I get the lower off and there is dirt in the lifter valley. I see light coming into the lifter valley from the front and realize that the dirt came from the timing cover being off.
So I pull the passenger valve cover and the head looks clean
I pull the head and BAM! more "chocolate milk" in #2. And then I notice #3 looks to be sticking out of the hole. I wipe it with a rag and its all carbon but the piston is dead even with the deck. Is it supposed to be like that? I figured the piston should sit in the hole a little bit 
I can see it now, it will need an entire rebuild
I'm gonna go pull the driver side head and see whats up. I'll keep you guys informed.

Other than water in #6 the driverside looks good. Both head gaskets were in good shape. I'm gonna make sure there isnt any oil in it and then pull the pan

Pan's off and everything looks clean. I tried to turn it over by hand and it doesnt move. It doesnt have anything to really turn it by (no balancer or bolt) and there is some surface rust in the cylinders so thats probably why. I made this thread cuz I'm bored incase any of are wondering why

Dont know about anybody else but i unlocked a 66 jeep gladiator engine with marvel mystery oil. I was just getting into cars at the time but that shit worked like a charm. Dont know the long term effect of the stuff though
That stuff will unsieze paris hilton from a credit card..... ive used it before on pressed wrist pins that were siezed on the piston itself and they came out easy with nothing getting damaged...
I'm not home but I will let you guys know if the motor is still siezed.

Even if the pistons arent seized you still wont turn it by hand without some form of leverage. If the rings and bores are in great shape with no rust there is still drag of the rings sliding along the cylinder wall.
If you have no balancer and no flywheel I would put the balancer bolt in(if you have it) stacked up with washers if necessary and turn the engine over with a breaker bar.
As for the pistons going to the deck, its probably normal. Im not sure about the 5.0, but some sit down a little below the deck, some are even, some stick up a tiny bit. Remember, theres normally a headgasket there that makes clearance between the piston top and the head even on a zero deck setup.
