If there was also an oil pump and head, I would suspect a broken timing chain or tensioner. A piece could have shot out and damaged the pan or pickup. I don't know if the vacuum pump attaches to the timing mechanism (all I've heard is don't break it or you'll end up with shards in the engine) so that could be unrelated. Seems odd to me that the timing chain would go that quickly - I think they usually go 150-200k before they are stretched enough to pose a risk.
