SparkyCNY Posted December 8, 2006 Share Posted December 8, 2006 For a 2003 Outback Wagon, 4 cyl, automatic, with about 85,000 miles. With the engine at idle and in park should I feel any back pressure if I put my hand over the oil filler pipe? Quote Link to comment Share on other sites More sharing options...
