So I flooded my engine, and there was a clank, and a sudden stop of my engine, would not crank back up. I figured I hydrolocked. So, I got the engine out which was full of water, and I took both heads off, got all the water out of the top of the cylinders. I honed them to get the surface rust, and everything looks great.. heads were fine and the valves were good. The one thing that is making me wonder is that I can't move the crank pulley to move the pistons. Counterclockwise and my crank bolt comes out, clockwise I get nothing. So is my next move to take out the pistons one by one to unlock her? Its a 2003 1500. 5.7 HEMI

 

You honed the cylinders with the pistons still installed?

 

This is a stretch, but, its worth a try before you start discombobulating the bottom end, put the transfer case i neutral and try rotating the crank around. Its possible the lockup shaft on the tranny is still engaged, by unlocking the transfer from the rest of the drivetrain----maybe. If it doesn't move, I'd be pulling the timing cover and checking the timing chain, then the camshaft, once the heads are off, and the tops are exposed, not much to stop it from turning unless something in the train is broken and jammed.

good Luck!

That must have been a micro-----micro bead hone too to get beyond the rings-----a scotchbrite pad might have been better for knocking out the surface rust

 

Yes I honed with the pistons still in. Just a little to knock off surface rust from the water. It was such a mild hone, I did not bore with it or mess the walls up. The engine is out of the truck and on an engine stand. I cant turn the crank at all.. maybe I'm not putting enough force on it, but she aint moving. I do plan on taking out all the pistons, but I dont want to.

 

With the heads off (zero compression) you should be able to spin the engine over at the crank bolt easily. Maybe take a 2x4 and on place it on the top of each piston and tap it with a hammer to break them free?

 

If you have it out of the truck on a stand, pull that thing down and finish the job!!

If it don't spin at this point you definitely got something broke, the fact that you stopped when you did may have saved you a block and crank. Its also possible you cracked a ring and its jammed on itself, which you HAVE no choice but to pull the bottom end apart. Bite the bullett and pull the pan---the sooner the better

 

Ok so I i got them spinning great.. all but cylinder 1.. thats piston is not moving.. all others are all cleaned up and the cylinders look great. Thinking a bent rod or something on piston 1? Noticed a code for cylinder 1 misfire before she died also.

 

Yep, sounds like you bent the rod in that cylinder...
