NO NOT in this hole! Just to the left of the expansion plug hole, that bolt that goes thru the front cover. Blurry, but the block is heaved in 30 thou just at that spot where that too long of a bolt was installed. So much for my hone stones!

So much for the stones, i would assume block is toast? A sleeve be a good choice?
 
I like threaded rod when it comes to that odd length front stuff. Thread it in hand tight, run a nut onto it and trim it with a cut-off wheel. file a 45 onto the end of the all thread and remove the nut. It will cut any buggered thread coming off.

I have seen that all the time when guys remove the power steering and use the same bolt after removing the bracket in front of the timing cover. I cannot believe it is not leaking coolant. You got lucky. I would go down and clean it up with a flap wheel a little then rehone. It should be below the rings if its from the bolt I believe it is
 
It isn't leaking yet, piston ring travel only begins to show signs of intersecting with the lump, the piston skirt doesn't go that far around to the side. The block is 30 over and was only going to get a deglaze, the owner has more blocks, he can decide. My self, if it was to be used again, it needs a sleeve!
 
Yep, I'd be concerned about hairline cracking in that area.

You gotta wonder what was said when they guys at Chrysler realized this..... it had to be something like the 'Rawhide' theme song: "Keep them doggies rollin'..." LOL
 
Just mag tested it this morning, YUP "star burst" shaped cracks at that heaved spot!
 
Seems hardly possible to not do that with cast iron... good that you checked.

Oh crap... I just looked at the pix of your hone... dang!
 
not the first time.....guy over here did the same Thing.....after that i was nervous and disassembled the front end of my Engine (still on the Engine stand) :)

Ok I’m lost. I do t see what y’all see. I’m trying to understand. It I’ve been up for 16 hours. Just got off work. Where is the bolt.
 
It's showing what happens when too long of a bolt is but through the water pump and timing cover when and bottoms out against the cylinder wall in the front of the block. Puts a nice bulge inside of a cylinder wall.
 
Look at the discolored spot in the picture of the cylinder bore... the cylinder wall is bulged out there.

One of the holes in the left front of the block is open into the water jacket and points right at the #1 cylinder wall. Too long of a water pump/timing cover bolt in that hole does not get stopped by anything until it jams into the #1 cylinder wall from the water jacket side of that cylinder wall. It busts the cylinder wall there....
 
I just can’t believe that this only seems to be happening the last few years. Of the millions that have been taken apart and assambled over 50 some odd years this isn’t more common. Kim

Rise of impact guns and air/electric ratchets??

I've always stopped when a bolt bottoms out. But most of my time working on cars has been using hand tools. I've worked on plenty of SBM's and never had an issue.

I am working on a cam swap and have that bolt out, and it has given me nightmares to think this could have happened when I put it back together. Number's matching motor, hate to do something stupid and easy to do and ruin it.
