or if ccv never been replaced do it now don`t wait another mile ,trust me I know. I lucked out with my 3.0i ,now I`m trying to get all that oil burnt out of the exhaust system.(my ccv froze this winter and dumped oil through the exhaust plus dumped oil into the intake onto the top of the pistons and hydro locked engine, but didn`t bend any rods ,which does usually happen.) thats my 2 cents.
