brycarp Posted December 13, 2010 Share Posted December 13, 2010 Time for "show and tell" now that my engine is pulled and the torque plate removed. (Car has about 155k miles, EJ22 engine.) Prime suspect: Plastic Oil Separator Plate - Guilty! (Notice that the rear main seal itself is dry as a bone. The tiny bit of seepage is from the crankcase join seam. The collective wisdom I received here was right on! Supporting role: Passenger Side Rear Cam Cap: I REALLY appreciate the great advice I got here. Now to do a bunch of cleaning and sealing. Fortunately I don't need this car for daily use right now, so I can take the time to do it carefully. Bry Quote Link to comment Share on other sites More sharing options...
Mugs Posted December 13, 2010 Share Posted December 13, 2010 Subaru actually makes an update kit for this. It is a metal separator plate and allen head bolts. Can't remember the cost but I think it was around 20-30 bucks. I have done them in the past... on the plastic plates. If there metal I just re-seal them.

Yup - already got the new parts and the anaerobic sealant. But I'm gonna do the cleanup before I pull the old plate. Quote Link to comment Share on other sites More sharing options...
brycarp Posted January 2, 2012 Author Share Posted January 2, 2012 I was going to point out this old thread of mine to someone asking about an oil leak, and noticed I hadn't added my "after" picture here. So here it is all cleaned up with the new steel oil separator plate: And the car no longer drips anything! Quote Link to comment Share on other sites More sharing options...
Olnick Posted January 2, 2012 Share Posted January 2, 2012 And the car no longer drips anything! Thanks for the update, brycarp. And congratulations! That "after" pic looks fantastic. Quote Link to comment Share on other sites More sharing options...
davebugs Posted January 2, 2012 Share Posted January 2, 2012 Folks often need this pic, and the understanding about the rear main. Thanks Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 2, 2012 Share Posted January 2, 2012 I hope you replaced the o-ring under the wrist pin cover too. I've replaced three of those in the past 6 months. All of them were as brittle as plastic and leaking. It's only another $1.50 or something like that and easy to replace while the engine is out.

danbennett2u Posted January 2, 2012 Share Posted January 2, 2012 What is the purpose of this plate? Is it covering an access hole for something? Sorry if that is a dumb question Quote Link to comment Share on other sites More sharing options...
ocei77 Posted January 2, 2012 Share Posted January 2, 2012 What is the purpose of this plate? Is it covering an access hole for something? yes, access to the piston clips for #3 and 4 pistons. O. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 3, 2012 Share Posted January 3, 2012 What is the purpose of this plate? Is it covering an access hole for something? Sorry if that is a dumb question The separator plate is part of the PCV system. It has baffles that catch oil vapor so it drains back into the oil pan rather than all of it getting sucked into the intake and sludging everything up. 1 Quote Link to comment Share on other sites More sharing options...

Bob Nieuwsma Posted March 12, 2014 Share Posted March 12, 2014 Can you get this plate from an auto parts store like Napa? or do I have to go to Subaru? Quote Link to comment Share on other sites More sharing options...

What was the choice of poison that worked so well? I use "the Right Stuff" brand sealant on both. I don't even bother with an O-ring on the small wrist pin cap......just a nice bead of Right Stuff.
