Question for all you out there with the Subaru EJ22. I have one out of a 1995 Legacy installed in a 1999 Forester...yes it wasn’t easy but it worked.  My question is i have installed new head gaskets, valve stem seals and rear main seal.  The rings looked good and my cylinder walls didn’t have gouges.  The engine runs strong but I notice that it smokes blue smoke on every cold start.  After about a mile of driving it goes away.  With no external oils leaks I’m burning about a qt of oil every tank of gas.  Oil looks good.  Could this just be PCV valve?  Or do I have rings that are glazed?  Not looking at rebuilding it again.   If the PCV do you recommend a catch can oil separator?  Or better system than the stock 95 setup?
