    Default Cracked 6.5L GEP/AM General Block

    Was going to upload pics but this sight has limitations on it i guess. Anyway have a 24,000 mile engine with all three 4 bolt main webs broke/cracked and nobody wants to stand behind it. By the way this is in a all STOCK 92 3/4 ton 4x4 with factory turbo. Just a little FYI for future buyers. $6500.00 Paper weight

    Interesting........ Keep us informed about this. What's the complete history of the engine?(supplier, install date, etc.) I was just talking to a friend today about wether I should buy a GEP engine to build an 18:1 on or just use one of my 'seasoned' blocks.

    If you have pics too large to attach to a post, upload them to the TDP Photo Album, and link them into the page. The Photo Album is available to all registered users, and the size restrictions are much more generous than the inline attachments, and it will automatically resize images to several sizes. PM/email me or a mod for help with this, if needed.

    Just a suggestion here. Please make sure that before you post the vendor you got it from, make sure you’ve contacted them and they refuse to warrantee or do anything for you. Not fair to post the vendor in a "no support" thread if you haven't checked with them first. I assume you have also contact AMG? You can contact them from their website, I've done it a few times and they are very responsive. It would be nice to know what their responses are.

    Very disconcerting if a new AMG crate motor cracked. Was your engine a complete engine including IP? Reason I ask is that I believe complete engines are test fired and the IP is set correctly. If not, did you or a mechanic set the IP? I would think that if the IP were set too far retarded it would probably put a lot of additional stress on the internals including the block webbing. Just curious.

    I went back and reread the original threadI have seen 3 of the Chinese copies now from 2 different sources and they did NOT have any logos that I recognized.If this engine in question did have a navistar Logo I wonder what the deal is?I am very suspect that this is some sort of bag of worms that was turned loose on an unsuspecting buyer. I have seen one bare Navisitar block in a local shop that had bought it from lord knows who.It was in fine shape according to the shop keeper (he is on the up and up always)It will be interesting to see any Pix if Klink ever posts any. I have asked him to send me some via my email but have yet to hear a response.We shall see.Robyn

    Since my Peninsular/AMG engine is in a diesel pusher, I can look all around the engine; anyone know where the casting IDs would be? I may even be able to take photos.

    Thanks! I have a pretty full dance card tomorrow, but will try to get pix of the casting numbers.

    I still would like to see the detailed images of the block in question. I've seen a few of the knock-off blocks and might be able to ID such a block if you've indeed gotten one verses the genuine AMG block.

    Without the images, the jury is still out.

    What would they have to say? They are only the foundry. They would suggest he contact his supplier, and nothing more. They may take in interest if a flaw in the castings were discovered in several, but they still won't take an interest in a warranty claim. Bark up the wrong tree, if you must. It won't serve your interest or provide a solution to the problem at hand.

    He's talking about the outfit, International Diesel, in Ronkonkoma, NY...not the foundry.
