I searched but couldn't find the information I saw on this sight previously. Was it the #53 blocks that were prone to cracking? Need to know, ready to make an offer on a truck. Thanks John

 

Thats correct. #53 cast in block under inj pump, right above pan.

 

If there is not a 53 or 54 etc and instead several small numbers/letters that are hard to read, then it is a Mexican Block which is great they are the strongest blocks made by Cummins and seem to be made of harder material.

 

Even if it is a 53 block truck that you are looking to buy, it shouldn't be a deal breaker! 53 block failures are still VERY rare. Go buy the truck and then stop and get a lotto ticket. You have a better chance of winning the lotto than you do getting a cracked block!

 

Thanks for the input. Now I'm just waiting for the salesbabe to call me back. John

 

Darn, mine cracked.... and I forgot to buy a Lotto ticket

Dezlpwr it had right at 60,000 when it started losing coolant. It cracked due to heavy use which is a symptom of the weak blocks. They crack near the turbo, a verticle crack that leaks to the outside, no internal leaks.

What block number did they replace it with?

 

I just got back from heading up the pass and smelled antifreeze and guess what? There is a 12-14&quot; horizontal crack just under the turbo. You guessed again block #53.

Take your power box off,<br>then take it to a Dodge dealer.<br>Its not your fault the block cracked.<br><br>Your Cummins warranty specifically states that the Engine block and all internals are covered.<br><br>--Justin

 

All I can find on mine is a 56. This truck is an 02 manufactured in July, and it was made in Mexico. Is the 56 one of the Cummins blocks shipped to Mexico? Just curious, but what makes one block stonger then the other. Was there a manufacturing mistake or what?
