TheSubaruJunkie Posted December 14, 2005 Share Posted December 14, 2005 I'll be reassembling my EA82T using a SOA Engine Gasket Kit. Has every single gasket i should need, from the oil pump to the rear main seal and everything in between. Im not sure if I should use a sealant on the head gaskets or not. I already plan on using a sealer for the intake gaskets, oil pan and some other various gaskets that like to leak (oil pump, valve covers etc). Can anyone recommend a sealant to use? Should I use a different type for different parts? Thanks all, -Brian Link to comment Share on other sites More sharing options...
WJM Posted December 14, 2005 Share Posted December 14, 2005 Fuji Bond. Get it from your local suby dealer. Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted December 14, 2005 Author Share Posted December 14, 2005 Let me guess.... $60 for a tube? Must I use SOA gasket sealer? and if i do is it for the head gaskets too or what? -Brian Link to comment Share on other sites More sharing options...
rallyruss Posted December 14, 2005 Share Posted December 14, 2005 no sealant on HG. copper coat is the only thing that can be used there. still I feel dry is best. most gaskets would be fine with out sealant but if you really want then permatex aviation sealant works well with a gaskets.

Subarian Posted December 14, 2005 Share Posted December 14, 2005 I use permatex aviation on most gaskets that are going to be in contact with water or oil, like water pump and oil pan gaskets. I always install HG dry, though. Link to comment Share on other sites More sharing options...
WJM Posted December 14, 2005 Share Posted December 14, 2005 UltraGrey is second choice from the Fuji bond. the tube cost me around $20 from subaru....ofcourse, i get a killer deal. Link to comment Share on other sites More sharing options...
rallyruss Posted December 14, 2005 Share Posted December 14, 2005 UltraGrey is second choice from the Fuji bond. the tube cost me around $20 from subaru....ofcourse, i get a killer deal. you will want one of these also to seal the cam housings to the head. I dont really recomend using it on the paper gaskets(intake) as it tends to spooge out the sides a bit. oh yeah no sealer on the exhaust flange gaskets either.

TheSubaruJunkie Posted December 14, 2005 Author Share Posted December 14, 2005 Naw, i wouldnt put sealant on the exhaust gaskets. I saw the crap that was on the old cam housings, thats what made me ask. That didnt look like your typical gasket sealer. Im gonna have to look into this permatex stuff. -Brian Link to comment Share on other sites More sharing options...

TheSubaruJunkie Posted December 14, 2005 Author Share Posted December 14, 2005 Good idea. I work as a construction equipment mechanic so it shouldnt be hard to locate a tube of the stuff. -Brian Link to comment Share on other sites More sharing options...
BoostedBalls Posted December 15, 2005 Share Posted December 15, 2005 I'm with rallyruss on this one. DRY is best unless the directions call for sealant. Most gaskets are designed to grab the sealing surface, and sealant will only get in the way and make things slippery. Some gastes come with a spray-on sealant that is heat activated, you don't want to put extra sealant on over it. Your head gaskets are squished with many tons of force. If you have leaks, you have other problems- improper torque, dirty or oily surface, warpage, cracks or scratches. I just installed mine dry and I'll be running 20+ PSI boost (confidently). The engine should get nice and hot, I'll let you guys know how the gaskets hold up. Link to comment Share on other sites More sharing options...
Snowman Posted December 15, 2005 Share Posted December 15, 2005 Good idea. I work as a construction equipment mechanic so it shouldnt be hard to locate a tube of the stuff. -Brian Permatex Anaerobic Gasket Maker is the same stuff. It works great for flanges like the cam towers and block halves. It also works very well on the oil pan gasket. Do not put any sealant on the oil pump or valve covers. Rubber gaskets and o-rings are NOT designed to be used with sealant. Especially on the oil pump, using a sealant like RTV would cause little chunks of it to break off and get into the oil passages...which is not good, to say the least. For intake manifold gaskets, water pump gasket, etc, use the copper spay-on stuff. It just barely coats the gaskets, providing a good seal without any excess sealant.

Ross Posted December 15, 2005 Share Posted December 15, 2005 no sealant on HG. copper coat is the only thing that can be used there. still I feel dry is best. most gaskets would be fine with out sealant but if you really want then permatex aviation sealant works well with a gaskets. The FSM actually specifies a sealant for the HGs (at least for ea81s it does). Link to comment Share on other sites More sharing options...
jacobs Posted December 15, 2005 Share Posted December 15, 2005 The old timers (racers) used to swear by hot stove aluminum paint on head gaskets. You paint it on both sides of the head gasket, let it dry, then install it. I've used it on high compression Corvette engines and never had a failure. Was it better than installing dry? I don't know. I've never used it on aluminum heads and or block. Just something to consider. It's cheep! Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted December 15, 2005 Author Share Posted December 15, 2005 naw im already set on installing the HG's dry. I feel SOA would have provided a sealant if they wanted me to use one. Just the other gaskets that like to develop leaks after 10-20k that Im worried about. -Brian Link to comment Share on other sites More sharing options...
Jibs Posted December 15, 2005 Share Posted December 15, 2005 remember to seal them good. Remember the Brat on the way back from wcss7 right? Link to comment Share on other sites More sharing options...
bratsrus1 Posted December 15, 2005 Share Posted December 15, 2005 Hey Brian This is Jerry, pm me with your address i have some gasket sealer that is really good stuff. I work on CASE backhoes and this stuff is made for case. It really works i use it on water on gas on oil on deisel on hyd oil heck on everything. This stuff works good- do not use on head gaskets but everything else. Also use it on the crank case when you put it back together it won't leak. Thanks Jerry Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted December 15, 2005 Author Share Posted December 15, 2005 Thanks for the offer Jerry, but It wont be necessary. I'll be able to get my own And Jibs... i dont remember you Brat leaking more oil than any of the other subes at the show -Brian Link to comment Share on other sites More sharing options...
soobscript Posted December 15, 2005 Share Posted December 15, 2005 Just so you know: the OEM gasket set does not have everything and has a few extras. I have it written down somewhere, but off the top of my head I know it is missing the EGR gasket, timing cover seals for cams and crank pulley, and exhaust gaskets except those on heads.

TheSubaruJunkie Posted December 15, 2005 Author Share Posted December 15, 2005 Hrmmmm.... I'll need to re-check the sheet that came with the gasket set to verify wether your right or not. I sure hope those gaskets are in the kit. -Brian Link to comment Share on other sites More sharing options...
