Default Saturday Morning Freak OUT! HELP PLEASE AM I SCREWED!!!!!!

Got up this morning to assemble the newly bored and honed short block "ej257" for my hybrid set up and was installing the bearings when i noticed this, i believe it is a coolant passage, its on the passenger side of the block on the upper part, there is a chunk that looks like it going to flake off, i bought the block from somebody on here and really must have missed this if it came like this to me, so either the machine shop did this or i bought it like this, what do you guys think i should do about this, is it really bad or do i have some options, I would imagine that if this flakes off i will be pooling coolant right into the crankcase and thats not good, check out these pics and let me know what you guys think, Thanks for any help.
By the way the other side of the block where this mates up to looks like it was sealing, and there is no coolant residue and doesn't show any sign of this crack, it looks like the seal was perfect and can not see anything wrong!

Yeah, that doesnt look good, but I bet JB weld, a little filing, and Subibond will easily make it good. Good luck.

Well, that seals with an o-ring, so the edge doesn't matter a whole lot. I'd just worry about the o-ring squeezing out the side under pressure. Some JB Weld and a little patience sanding it perfectly flat should do the trick, I think.

If you have the ability to get it welded and maybe know someone to plane it flat, and you don't mind waiting, that is definitely the ideal solution. Remember, that block is cast aluminum, so not everyone can weld it (read: no muffler shops).

Car has been under the kNife for 2 months WAITING if you guys think jb weld will hold up i would be happy with your advise, and would like to get this thing together relatively quick, What do you guys think the cause of this may be. I took it to the Machine Shop wrapped in bubble and took it home from the shop wrapped in bubble wrap, the side that is cracked is probebly the side that faced down on the Bore/hone machine. Any IDEAS!!

Well, you can try to get them to fix it, but it's all in the approach. Good luck if you decide to go that route.

The JB Weld... while I think it would hold, if serious pressure built up behind it, there is always a possibility that the JB Weld didn't have enough cohesion to stay stuck where you put it. Basically, if it was me, I would do it on my block, but I wouldn't do it on anyone else's block.

Hey
Dude ,the only thing I would be concerned w/ is how deep internally does it go ?
It's a main oil passage , looks like in front , right underneath the oil sending unit .. ? I would not risk welding it for fear of warping the case.jb weld is probably the only safe option, @ least its facing inwards
regards

it only goes about 1/16-1/8 " into the block down towards the oil pan, it should take only a minute or two to file out, thanks for the info

That sucks man. I know how it feels to have a long term project suddenly hit a roadblock like that. Good luck.

So i went to the shop locally and told them about the crack he very kindly said it may have been dropped or rocked on the table and i agree sh))t does happen, he took the block halve from me and said it would be fixed, i left the shop and headed to work, about an hour later he called me up and told me it was fixed and was no charge, Thanks alot DONNY @ engine rebuilders "53186" everything looks great and got it done in no time, picked it up today and went home to start putting it back together, Do you guys think that a .002 oil clearance is good for the connecting rod bearings i got the plastiagauge used it /worked great , also kinda hit a bump_ one of the rods does not have the clearance like the others, feels like 3 out of the 4 have about .020 play side to side, nothing up and down, but the one has "feels like" .005 play any worries or concerns i should have with this!??
