I was racing with few guys and i was in 3rd gear redline and missed gear and accidentally got it into 2nd

car did brake (with engine) really fast but i pressed clutch and rolled of the road. And noticed that engine noise is bit louder than usual, but after 15min of normal driving everything was fine. So i thought its time for another vtec run and after i done it, my car was shaking on idle, engine got way louder( its louder than my exhaust) Went to garage and they said it could be cambelt or tappets are lose.
But i will leave it in garage only on friday , and i wanted to know if its safe to drive it? I need to get to work
Anyone ever done something like this?
And any ideas, what happened with engine?
