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?

new ignition coils could have revealed developing problem. try oil stabilizer on next oil change to recondition seals and cylinders.
