rojo412 Posted February 9, 2013 Share Posted February 9, 2013 I know this may seem like an odd question, but I ask out of curiosity, as well as practicality. The part in question is part #6 on this diagram... http://static.opposedforces.com/epc_img/366494903102.png It was discovered in the midst of my head gasket job that it's split and should be replaced.. It's an o-ring... There's some shaping and all that, so I guess that's what Subaru believes makes it a $16 o-ring (at the dealer). But is there any alternative to it? It doesn't seem to be a high-pressure seal or anything like that. And if I could get by with anything else, I'd love to know what that might be. If I'm wrong, please explain. And I don't plan to omit it from the job, but if a $1 o-ring would perform the same task, I'd be inclined to use that instead. Thanks in advance for learnin' me on it.

SpecBamf41 Posted February 10, 2013 Share Posted February 10, 2013 your ring its not under presure all. honestly i almost forgot to put it on. it is a very odd seal but i dont see why a normal oring would not do the trick. BNR18g on 93oct Link to comment Share on other sites More sharing options...

Make sure that o-ring is rated for oil and temperature. Oil pan leaks suck, because dropping the pan is a pain in the crotch.

spooln30 Posted February 10, 2013 Share Posted February 10, 2013 It is just a oil drain back but I would recommend replacing it otherwise the oil won't fully drain down below the second baffle fast enough. The oring for the oil pump pick up is very important or you'll lose oil pressure. Dropping the pan isn't that bad it's reinstalling them. I usually just remove the pick up the when I am reinstalling the pan I finagle the PU back in place. Less time this way then undoing the 3 mounts and lifting the engine.

rojo412 Posted February 10, 2013 Author Share Posted February 10, 2013 My buddy has some Subaru o-rings that seem to fit close, but aren't perfect. I know I don't want to drop the pan after this motor goes back in, but since this part seems to be pretty simple and low risk, I figured I should ask.

SpecBamf41 Posted February 10, 2013 Share Posted February 10, 2013 its just a drain from that area with the cover plate in the bellhousing. really not alot of oil in there during normal driving BNR18g on 93oct Link to comment Share on other sites More sharing options...
rojo412 Posted February 10, 2013 Author Share Posted February 10, 2013 So basically, if I can match the height and diameter with an oil and temp rated ring, I'm gold... Link to comment Share on other sites More sharing options...
spooln30 Posted February 11, 2013 Share Posted February 11, 2013 Yep, it should work. Link to comment Share on other sites More sharing options...
