Dude, if you want sympathy, you wont get it here until you produce the proof everyone is asking for. If your engine is a true brand new AMG engine, you have my sympathy, if you tried to skin a fat hog & get away with something, oh well. No one has heard of a real AMG engine cracking, thus the skeptics. Nobody reading your posts is going to warranty your engine, & there is a lot of negative feedback on the outfit you bought the engine from. All we really want to know is if it is a genuine AMG engine that was built in their factory. Quit beating around the bush & let us know.
