Can replacing all ignition coils cause engine ticking noise? on 2006 BMW 330i

I just had all of my ignition coils replaced. Afterward I began to smell what seemed to be burning oil while driving. The smell stopped and now there is a ticking noise coming from the engine. Could having the coils replaced have caused damage to the valve gasket cover resulting in the ticking noise suddenly starting?
