hey guys im in a rare opportunity to hit up a Subaru dealer this weekend. id love to get my pcv hoses replaced(they are hard as rocks and leaking vacuum) but I fail at internet search and cant track down the factory numbers for the rubber hoses connected to the aluminum pipe that crosses the timc and the couple that run under the intake. the three on the cross over pipe are the worst leak offenders, those are my priority. anyone with a old parts diagram? any help would be geat, thanks.
