As a two-year old follow up to this post. I got a quote to have the oil coolant lines changed for around $650. I bought the parts for around $40. I changed them all out, which took about two hours and included the o-ring and gasket. Not a drop of oil for about a year. Then the oil started leaking again. I took it to the dealer for some other problems and had them changed while the thing was in the shop. Leaks were fixed again. It has been about another year and I have oil dripping again. Shouldn't these things last longer than a year?
