In March 2012 I learned that my left headlight cluster required replacement because of a broken element. I postponed replacing the headlight assembly until now. Head gaskets leaking externally, possible damage to cylinder heads; also, faint clanking sound emanating from engine suggestive of damaged bearings A faint clacking or knocking sound from the rear when I turn. Most noticeable when I accelerate into either a sharp turn or a wide sweeping turn. It is more noticeable upon turning left than right, but intermittent. Technician could not detect it.
