Ok: I canâ€™t be the only one this unlucky!

My â€™90 has 110k miles. Last week while driving into town the engine started ticking.

To me it sounded like a collapsed lifter. I localized the noise the area of #7 cylinder. Further inspection reviled a missing screw on the secondary throttle plate for that cylinder. Has anyone had this problem? Were you able to recover the screw without pulling the head? Can the head be removed & replaced without taking the engine out of the car?
