06SubLegTx Posted May 1, 2017 Share Posted May 1, 2017 I'm sure this has been asked before. What Sealants are to be used on these applications? Oil Pump: Oil Pan: Rocker Covers (I know there is a seal that is there already, but from what I have seen "on the net" is it still doesn't hurt to run a bead around the Cover Lid Lip) true or false, if so what kind: Transmission Pan: Thanks Quote Link to comment Share on other sites More sharing options...
Mike104 Posted May 1, 2017 Share Posted May 1, 2017 Subaru Dealer mechanics use Fuji Bond and say its the best. I've used Permatex Gray and it leaks. According to my son (Subaru Dealer mechanic) they now use THREEBOND TB1217H https://www.flatironstuning.com/p-2919-subaru-three-bond-tb1217h-new-fuji-bond.aspx 1 Quote Link to comment Share on other sites More sharing options...

When I took the heads, intake, oil pump, oil pan, I looked kinda gray color... Thank you, Mike Quote Link to comment Share on other sites More sharing options...
Mike104 Posted May 1, 2017 Share Posted May 1, 2017 Apparently the original Fuji Bond was black, then grey and now apparently red Quote Link to comment Share on other sites More sharing options...
Mike104 Posted May 1, 2017 Share Posted May 1, 2017 I think the only exception was to use an anerobic sealant when installing the oil pump Quote Link to comment Share on other sites More sharing options...
06SubLegTx Posted May 1, 2017 Author Share Posted May 1, 2017 Apparently the original Fuji Bond was black, then grey and now apparently red So, the big question is: which one is better? I will ask the guys at Subaru tomorrow... Have you ever used the Gray stuff? Is it good? Know where I can find it? Quote Link to comment Share on other sites More sharing options...
lmdew Posted May 1, 2017 Share Posted May 1, 2017 I've used Gray RTV on all of them and it's worked well on many engine and transmissions. Clean the surfaces well and then I let it cure 24 hours before I put fluid in an start it up. Most Subaru Valve Covers have there own seal and it goes on dry.

moosens Posted May 1, 2017 Share Posted May 1, 2017 "The Right Stuff" has worked perfectly on my oil pumps for two cars at least and probably 200,000 miles between those cars. Subafreak advised me and he is a Subaru Tech. Yes , Fuji bond is great too. But you can save some money and I attest that it'll work.

GeneralDisorder Posted May 1, 2017 Share Posted May 1, 2017 The newest iteration has all the sealants being replaced with Three Bond 1217H. This is MUCH cheaper from the Nissan dealer. It's about $15 a tube vs. nearly $40 at Subaru. GD Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted May 1, 2017 Share Posted May 1, 2017 I have used the permatex ultra-grey to good effect on my H6 oil pan. On that car the pan is a little cover that goes on at the bottom of the pan, it actually has to hold in the oil. At the time it was stated to be effectively the same as the fuji-bond. The ultra-gray isn't really like silicone at all. Quote Link to comment Share on other sites More sharing options...
