Joined this forum looking for some installs of oil catch cans on the new Foresters. I couldn’t find any. Figure I would post the setup I installed on mine. I used a Mishimoto oil catch I purchased on Amazon. I purchased PCV rated bulk hose from the parts store. I read that some guys are running heater hose on their setup. I would advise against that. Heater hose isn’t designed to transfer oil. I imagine the heater hose will get soft and spongy in the future. Subaru uses 5/8(ish) hose on the PCV. The nipples that come with the catch can are 1/2 barb to 3/8 NPT. I was unable to find 5/8 barb to 3/8 male NPT fittings at Lowe’s, Home Depot or the Grainger by my house. Grainger could get them, but special order. I purchased machined aluminum barb fittings off Amazon instead. The catch can comes with a bracket and 2 self tapping screws. I like the mounting position I chose, but draining it could be a bit challenging. I like how the can is a bit hidden and close to the PCV valve and intake manifold vacuum port. Removing the catch can for draining will likely be easier vs using the drain plug with the location I chose. Will drain the can every oil change. I service my cars at 5,000 mile intervals but will check the can after the initial 1,000 miles. I have some heater box/evaporator insulation tape in my tool box at work that I plan on wrapping around the A/C line right above the catch can to protect metal to metal rubbing. There is some clearance, the line doesn’t hit with the engine idling but may move more on hard acceleration.
