Prospeeder Posted February 7, 2007 Share Posted February 7, 2007 ok, in auto i got the whole thing apart, but my auto teacher says, if i never want to have to do this for a long time, or ever, that i should use this Anorberic (SPelling?) THe stuff that doesnt harden unless its not exposed to oxygen and turns to a plasticy sort of sealer. He wants me to put a thing layer of that on the gaskets, both sides. Should i do this? or am i asking for it to fail, i REALLY need this thing to just stop leaking, im not into doing this Again. Also, is there a torque sequence, i know its 14-16 lbs, but what order should i torque them? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 7, 2007 Share Posted February 7, 2007 Dealer only. NO SEALANT. The proper gaskets are graphite impregnated metal - just like a head gasket. And just like the HG's, they are designed to be installed dry. Clean the mating surfaces with a wire wheel. Clean the bolts with a wire wheel, and chase the threads in the heads with a tap. Torque to 12-14 ft/lbs with a 3/8" torque wrench. There's no sequence. If you use the cheap cardboard aftermarket gaskets then probably use a sealer on them - but they will fail no matter what you use. There's a reason Subaru doesn't make them from cardboard.

hatchsub Posted February 7, 2007 Share Posted February 7, 2007 +1 no sealer. I installed mine dry and took my time making sure both mating surfaces were clean and flat. No leaks yet!! Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 8, 2007 Share Posted February 8, 2007 I'll add that I have NEVER had a properly installed OEM gasket fail. I've blown TWO sets of Fel-Pro cardboard units....:-\. They just didn't do their homework on those. GD Link to comment Share on other sites More sharing options...
Prospeeder Posted February 8, 2007 Author Share Posted February 8, 2007 ok thier dealer gaskets, so no on the sealer. I got brand new bolts from the dealer. So ill make sure everything clean and what not then, thanks! Link to comment Share on other sites More sharing options...
Frank B Posted February 8, 2007 Share Posted February 8, 2007 What's the Subaru part number for the intake gaskets? I need to pick up a set for the hatch. Link to comment Share on other sites More sharing options...
Prospeeder Posted February 8, 2007 Author Share Posted February 8, 2007 besides a wire wheel what can i use, like a 600 grit sanding block? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 8, 2007 Share Posted February 8, 2007 Wire wheel works best. Sanding removes too much material, and unless done very carefully with a perfectly flat surface will result in a warped surface. That, and 600 grit wouldn't do squat. It would clog too easily. Get a wire wheel. GD Link to comment Share on other sites More sharing options...
daeron Posted February 8, 2007 Share Posted February 8, 2007 I will repeat, don't forget to clean the threads in the heads out with a thread chaser. You should have one in your shop, hopefully. If not, "to do it right" as your teacher said, you should go buy one. The new OEM bolts are worthless if you forget that. good luck convincing your teacher that the internet was right Link to comment Share on other sites More sharing options...
Prospeeder Posted February 8, 2007 Author Share Posted February 8, 2007 know exactly what size it it, there too small for anything my shop has. Link to comment Share on other sites More sharing options...

THe stuff that doesnt harden unless its not exposed to oxygen and turns to a plasticy sort of sealer. It wouldn't hurt if you coated the gaskets with the same non-hardening sealant used to join the two block halves, but it's probably not needed as other people said.

Actually it will hurt - you will prevent the graphite from bonding with the aluminium. If properly installed, dissasembly should result in the destruction of the gasket as it bonds to the aluminium sufaces like a head gasket would. This is why the surfaces must be COMPLETELY clean. All the failures I've seen were related to cheap gaskets or poorly prepared mating surfaces. GD Link to comment Share on other sites More sharing options...

4x4_Welder Posted February 9, 2007 Share Posted February 9, 2007 If you ever think there might be a remote possibility that somebody somewhere down the line might have to pull the intake again, use anti-seize on the bolts. If you didn't break a bolt taking it off, you're extremely lucky. Link to comment Share on other sites More sharing options...
[HTi]Dain Posted February 9, 2007 Share Posted February 9, 2007 So are the intake gaskets on an EA81 the same as EA82--OEM graphite? Link to comment Share on other sites More sharing options...
Prospeeder Posted February 9, 2007 Author Share Posted February 9, 2007 the first time i did it, it broke a bolt, that time i used antisieze so this time they came out fine. Link to comment Share on other sites More sharing options...
SOOBOUTLAW Posted February 9, 2007 Share Posted February 9, 2007 ALWAYS use antiseize on your intake bolts, they break so easy after 150k miles. It's a B(female dog)h to drill out and rethread or helicoil.( I like Helicoil cuz they will last way longer than crappy soft aluminum thread. Especially when you dismantle and reinstall occasionally)(sp?) Link to comment Share on other sites More sharing options...

Non setting goo is for use on paper gaskets and the like only. Link to comment Share on other sites More sharing options...
