You tell me. Or rather someone proves it could. Unless plugs were out or head off how is it even possible?

Size tbc. May need new valves (x 4?) Or maybe new head.

I had a Jeep CJ 7 and mech managed to leave good size bolt in the inlet. Massive clattering sound back to mechs. They removed it with a magnet on a stick through the spark plug opening, checked the compression; all fine!!!! Never had a problem after it. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

Very, very lucky, bet it wasn't a diesel! It can when others can't,
It will when others won't,
It goes where others don't.

Can you get a picture of the screw? Maybe we can identify it?

Is it possible to drive for a year 12000 miles with a screw in one cylinder? Sounds mental to me

It has probably been sat in the intake some place, and has sat lodged there until the right conditions have been met to dislodge it
Has it had any other engine work done? Thinking more timing belts or inlet manifold work My D3 Build Thread
