I know the cracked manifold issue is very common on 430's, but how much of a problem is it with 360's ? I am aware that the consequences are serious with 430's due to bits of the precat material falling into the engine, but I thought the 360 has a different manifold design without precats? If so, what are the consequences of driving a 360 with a cracked manifold? Being a novice to Ferrari ownership, I am just trying to think of any preventative measures to keep my car running perfectly.
