Hi all,

Noticed a strange noise this morning after driving for about 50 miles on my 94 S500 (didn't have it last night). The best way to describe it is it sounds like a diesel engine, more pronounced on the left side (ticking and tapping). I know its scarce, but what can I be looking at? The oil pressure is fine (3 while moving and 1 at idle), the power is fine (or looks that way). What can I be looking at here, potentially?
