Re: 03 seville pcv location
Remove the plastic engine beauty cover. In the left (front end) of the right (rear) camshaft cover is a plastic line which snakes into the front (accessory belt) end of the engine. There is no PCV valve per se: there is a fixed orifice in the cam cover which is connected to manifold vacuum in the front of the intake manifold. The clean air source is the plastic line which comes from the throttlebody to the (right) end of the front cam cover.
