Just thought i would give you guys an update from my last situation.
problem:
2004 WRX smoking blue from tail pipe every once in awhile. no miss, some oil present in intercooler piping, no play on turbo shaft.
solution : changed oil back to amsoil 20-50 and problem has ceased to replicate itself (over 5k miles ). still boosts fine and all seems to be well. previous oil used was amsoil 10-40.
hope that helps someone in the future.
