But i am not sure the v6 is a volital engine any help in figuring out what could of happne would be appreciated. and it wasn't started for about 9 months

Check the valves for being bent or pitted. If so replace. Or just find some used low mile heads and forego all the crap. It sounds like oiling could have been an issue (understatement!) but it had to be something real extreme to have caused this type of failure. Are you sure it had not already happened nine months ago?? Sounds like a real hard drive had or HAS taken place since youve put in the shop!

As I understand it to mean is, lets say the timming chain/chains in the engine failed, some valves of the engine will come to a stop, with some of them open. The crankshaft/pistons with a lot more mass will not stop as fast and the pistons would smack into the open valves. The computer has nothing to do with it. Is the V-6 engine really a Non Interference Motor?
