Anyways.. how does the timing get messed up, and how do I fix that?



The hiss/whistling is definitely a vacuum leak.

Did you guys tear apart the front of the engine at all? If so, when you put it back together the timming marks might have not been lined up. If the timming sprocket on the crank is spining back and forth, that will throw the timming off x2 on the cams. Without being there it is hard to diagnose exactly what is wrong. The best way to tell if the crank bolt is loose is to reach down and try taking it off with your fingers. If you can, it is not torqued down. I believe the torque on it should be around 150ft-lbs.
