I found some part numbers for PCV hoses recently.
here is an image with part numbers.
Upper 3 PCV hoses, all 3 connect to Breather Pipe that runs across TMIC. These can be found under Emissions/PCV diagrams.
99071AB103 NA-passenger side, from head/crank case to Breather pipe
99071AB420 NA-passenger side, from Inlet hose to breather pipe
11815AB502 or 11815AB960 NA-driver side, from head/crank case to breather pipe.
Lower 2 PCV hoses, these can be found under Water Pipe diagrams. they run from head/crank case to a pipe under the intake manifold.
99071AB333 NA-passenger side
99071AB343(MY01-MY05?) or 99081AB060(MY06-?) NA-drivers side
This link shows how the diagram can be incorrect. they show an image of 99071AB343, but they link to 99081AB060, see item 99081.
This opposedForces diagram shows image of 99071AB343 and lists 99081AB060 for 06+. My Forester Xt 06 uses 99081AB060, but all catalogs point me to 99071AB343.
