I have a 94 acura vigor. Something blew out of the top of engine. on 1994 Acura Vigor

What blew out? It's a 5 cylinder engine with 5 wire connections into holes on top of engine. Is my engine shot or repairable. Thank you for your help.

Sounds like a spark plug was loose and blew out. Does it run , but make a bad popping sound-like an exhaust leak?................Very late response ........but if dmash6 sees this since I was enough of an idiot to reply to a 10 month old posting , could you let me know if I was close? curious .
