Leviman Posted September 8, 2012 Share Posted September 8, 2012 Is that truly a crack? Looks like it's right at BDC, why would it crack there? Link to comment Share on other sites More sharing options...

ehsnils Posted September 8, 2012 Share Posted September 8, 2012 Failure in the casting process. Depending on how deep it is and location it can range from harmless to a coolant leak. Link to comment Share on other sites More sharing options...
fahr_side Posted September 8, 2012 Share Posted September 8, 2012 Oops. Given the location I'd say it's a manufacturing defect and no fault of yours. Of course most major blow-ups start with or at a tiny flaw, so good call on scrapping the block.

shtbxr22 Posted September 11, 2012 Author Share Posted September 11, 2012 Yours is probably a ringland, or valve adjustment issue. Link to comment Share on other sites More sharing options...
Max Capacity Posted September 11, 2012 Share Posted September 11, 2012 I think I have cyclinder2 problem... keep throwing miss fire code... do tell me more bout your #2?? There is a timing flaw in the OEM engine map. The issue results in burnt valves. For some reason #2 seems to be the first one to go bad enough to start the CEL. Tuners have found the flaw in the map. When I mentioed that to my Machine shop buddy, he said, "that may explain why we see so many heads from the Dealerships with burnt valves". When they rebuilt my heads, they could see a difference from what they are used to seeing with these heads. I have been in Cobb AP or a custom tune since 8000 miles on the car. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).
