i have the amuse style vented hood. the vent let the water falls right into my engine bay,(directly on the pullies)

IS THAT OK??

 

Yes, from what I have heard that is no problem.
In the old days engine bays were more susceptible to water damage wiring, fuse box, ect. But they make everything pretty "waterproof" now.
There are many people who hose off there whole engine bay when cleaning the car. Myself included. You just don't want to get water into the intake.

 

Water splashes in from the bottom anyway.
