Why would he think he has a cracked cylinder wall? What are the symptoms that would cause him to think this w/o having taken the motor out?? If the block has a visible crack that is leaking thats a different story...Rebuilds ALL depend on who does the work....You might want to check ebay..I see BRAND NEW 5.4L engines all the time and they go for around $1200-$1500.00...Definitely a better option than rebuilding. UNLESS you want to toughen up the internals.......

That's what I am thinking... Just get a new engine, you are going to same a ton of money. Also why does he think it is a cylinder wall?
That means you need a new block if you have a cracked cylinder wall, not the components in the engine. I dont know, Im confused.

Don't think anyone sleeves the 5.4 Iron blocks...only 5.4's I'm aware of that get sleeves are SHM aluminum modular blocks....and I don't think he'll be getting one of those...
Anyway, if he's looking at a rebuild he may as well get a good forged shortblock for VT Engines or SHM or anyother company that specializes in building modular Fords. I think the VT shortblock runs about $3,800 not including freight. The 5.4 blocks are damned stout...takes something seriously wrong to crack one..maybe he's just loosing a rod...those and the pistons are the weak points in these motors.

BTW, I raced a showroom stock smallblock MOPAR back in the '70's. When we rebuilt that engine, in order to keep it legal in class, we put eight sleeves in it and bored it back to standard size! No problem. Would be cost prohibitive if it was not a race engine.

I have no idea what went wrong - don't know if it sucked a valve then detonated the piston and connecting rod or what...I've got pieces of the piston and the rod (the half that connects to the piston). The rod is twisted at the broken end.
