ok i just did a series of shit to my 94 civic, i replaced the timing belt, water pump, radiator, spark plug wires, thermostat and after all that the car started but i heard a valve tap. so i took the valve cover back off and adjusted the valves just alil bit to tighten them, put everything back together and went to start it and nothing all i hear is the starter rotating the engine. took the valve cover off to see if i might have bent a valve and i saw the valves were moving like they would normally(had a friend start the car while i was lookin). so any ideas on what i missed or if i messed my car up would be helpful.......
