1984 Mercedes Benz 300cd Two Wheel Drive Automatic 242000 miles

My 1984 Mercedez Benz 300cd engine was just recently entirely overhauled.
While on the freeway, the engine started making a loud noise, like it was stuck in gear only much louder. Soon after, I could hear something fall out from under the engine and smoke came out from under the hood. What looked like a rectangular bracket about shoe box size fell from the engine completely charred, and the air intake hose had a crack in it. I was able to start the car again with some effort, but a lot of oil spilled out when the engine turned over and it did not sound right. The shop it is at is saying the engine block is cracked. I don't believe this, rather I think it has something to do with the air intake/overheating. Any ideas? Thank you

The first thing I would like to know is what pack of Indians were chasing you, that you could not stop when you first heard the noise? We do not live in the time of "Dances with Wolves". Considering the fact that you had the engine "entirely overhauled" at only 242,000 miles tells me that you are very experienced at this. The piece of metal, you are describing is a Rod and most likely the mechanic is correct. The engine block is cracked. Nice job, next time, and I'm sure there will be a next time, make sure all your fluids are up and look at your gauges Instead of texting on the phone and listen to your vehicle, instead of talking on your phone while you are driving. Good luck.
