Why does it matter? Its obviously cracked but most people on this site know it as a porous block.

This thread is scaring me lol.

I have a 2009 SS Coupe that's a 10/2008 model. I don't know how to tell where it was made, but no porus block yet. I have 18,850 miles as of now.

 

Where does the block crack or become porous? Is it a central location for everyone?

Reason I ask is because I had a similiar problem when my aftermarket filter sucked water into the motor. Insurance rebuilt the motor once, and it spun the #1 main bearing, the dealer rebuilt it a 2nd time under the assumption it was improperly done the first time, and it spun the same bearing and cracked the cylinder in the process.

They claimed the cylinder was cracked from the beginning, so there may be a weakspot in that section of the block.

 

bump

 

hate these threads... scary lol

 

Build date on mine is 08/08 hoping im safe lol

 

forgot about this, will get build date when i get home

 

Info is already looking good!

 

There has got to be a reason the LHU and LAF blocks are sandcast instead of lost foam. The LNF wasn't out long before they updated to the LHU.

 

i no this thread has been dead for awhile but does anyone have anymore information on this? im having this problem as well and now the dealer is giving me **** and doesnt want to fix it.

 

I am curious also. My build date is 11/08
