davebugs Posted August 24, 2013 Share Posted August 24, 2013 You sure? By that I mean long ago folks here recommended MMO for noisey 2.2 and 2.5's after they have been setting for a whiel or after no oil - like a HG job for instance. MMO and a spirited drive helps a lot. But usually that's cams n stuff. Top end noises. Link to comment Share on other sites More sharing options...
Fairtax4me Posted August 24, 2013 Share Posted August 24, 2013 How fast does the oil pressure light turn off after starting? When you took the heads off did you pull all of the shims out of the buckets for the valves? The shims set valve lash clearance and can not get mixed up. They have to go back exactly where they came from. Link to comment Share on other sites More sharing options...

davebugs Posted August 24, 2013 Share Posted August 24, 2013 MMO and a spirited drive always did it for me. Had never used MMO before Subaru's. Link to comment Share on other sites More sharing options...
