Engine And Engine Cooling Related Problems of the 2008 Ford E-250

Engine And Engine Cooling problem

Thankfully I was driving slowly between curves on a stretch of roadway with a 30mph speed limit (one lane each direction) when I �blew a spark plug�. The coil was also damaged I was told. I was also told there's no guarantee that it would never happen again, and I have 7 other spark plugs and coils in the engine, so expect it. Allegedly 3 were replaced just before we bought this used in 2016. I tried to get receipts for vehicle maintenance records, but the shop refused and the private owner had moved and thrown her paperwork away. This was in massachusetts. I had no warning, that I know of. Suddenly there was a loud bang and a repeated bang, bang, bang! I pulled over immediately. (thankfully it wasn't a 3 or more lane highway with my mother in her wheelchair!) the banging only stopped when the engine was off. I was unable to look at the engine compartment with the van on because I was afraid of more damage! it was put on a flatbed and towed by aaa, to a shop a few miles away. Unfortunately, this shop couldn't get it inside to work on. A friend of mine did the repair in the parking lot. ***apparently this is a very frequent problem with these Ford e250 engines. There is a lot of people experiencing the same problem. I had no idea! it could be extremely dangerous on a multi lane highway, traveling at high speeds, going up and down the mountains (I travel between nys & massachusetts), in subzero temperatures especially with someone in a wheelchair onboard!*** I have no receipts. Aaa of central NY should have a record of the tow.
