These are OEM Subaru OCV's (Oil Control Valves)
Common symptoms that may be a sign that these need to be replaced include:
-a P0011 / P0021 fault code
-stumbling at low rpm
THAT sounds familiar.. (except for the codes). Am now trying to find out how much work it is to replace these...
tried this. cost about $157 CAD each (two of them) it corrected the rough idle... for a bit. but i think the fix was more related to the ECU reset... a day later ROUGH IDLE !!!! ahhh!!!
I also noticed a tear in my turbo inlet... had the turbo rebuilt once... crap! Also cleaned my throttle body. My next step is to replace the inlet hose, then maybe the manifold gaskets.
