If you like a VF46 and you're considering your options, I'm happy to give further info on my ported VF46 that has just come out. It has more shaft play than a person would want but it still ran fine and was driven with mechanical sympathy (noting that small turbos have a harder life). If you are spending money on a VF46 rebuild, a ported one could be a good start. No obligation obviously.
Checks upper rear right of block looking for oil leak: it’s the sump breather hose, one of the two primary *block* pcv hoses.
Replaced the cracked pcv pipe with a diy suction hose made from heater hose with a stretched compression spring inside.
Intriguingly this pipe does not appear on partsouq, opposed forces diagrams.
I did find it in the Baja diagrams, in the FSM, and in dealership diagrams that use Subaru FAST EPC. Weird.
Was it a 19mm ID "slightly Z-shaped" hose off the rear crank breather?
Mine (2008) had this but does not show up on partsouq (straight 19mm hose piece to plastic T shown) and even ordering that older style crank breather assembly gets you the new 2009+ "F shaped rubber moulding" based system for $160+ (no thanks).
Because I'm running catch cans I ended up grabbing an Aeroflow (?) silicone right-angle reducer (19mm to 13mm) to come off the crank breather, up over the gearbox (next to the turbo) then (with 1/2" barbed straight joiner) off to the rear catch can.
