Did anyone notice a leak coming from the pump (or the hose itself) prior to replacing their o-ring? I have an accumulation of some kind of fluid, either engine oil or PS fluid that is on my pump and collecting on the timing belt cover, so I'm not certain where it's originating from. AFAIK, the pump is original with 123k miles on it, so I'm going to replace the O-ring anyways, but I'm curious to see if this is a common issue with leakage.
