Check to make sure the vacuum line for the brake booster is not leakind and the fluid level is okay. The rush of air and loss, check the battery cables at both ends. Also look for vacuum leaks in hoses in the engine bay.

Oh, that sounds like you blew your engine. You might have blown a head gasket or spund a bearing and lost some soolant, which would make the moise easier to hear, and/or oil. The knocking is not a good sign along with the issues you describe. It almost certainly sounds like a mojor engine overhaul. You could probably find a good used engine for around $1000-$1500 depending on how many accesories came with it.
