To make a long story short, due to an unfortunate series of events I had a loud knock coming from the engine.

Finally got a chance to get under her and drop the pan, and this is what I find (in the pan):




So, looking for where it came from.. Looks like the cylinder wall of #2. Block is done for (first pic is #2, second is #3 which is normal)






Anyone selling a block? Or know where I can get one at a good deal?

 

dam that sucks man. looks like a flaw in the molding of your block

 

That's visable once you take the oil pan off?

 

My block cracked in the same spot but it was while the dealer was removing the piston. The tool they
used cracked it in the same spot. New block for me.

 

HOLY PORUS BLOCK BATMAN!!! That thing looks like it was made in styrofoam.

 

i have a whole LSJ motor sitting in my garage for sale

 

This a joke right? it is styrofoam casted lol

 

this! I was gonna say something to this effect. Styrofoam mold.

 

 

Take your parts off, claim porus block and bitch up a storm. New motor.

 

Most of GM's aluminum blocks are cast that way.
Other brands as well.
