06SubLegTx Posted May 7, 2017 Share Posted May 7, 2017 Hello, I'm going to use Fuji ThreeBond 1215 Gray Silicone Sealer: If you have ever used this sealer, I have a few questions. Oil Pan: 1. How wide of a "bead" to you run around the base of the Oil Pan? 2. Do/Did you run the bead "around" the mounting bolts, or just one side (inner or outer). 3. How did it hold up to leaks? Thanks Link to comment Share on other sites More sharing options...
Max Capacity Posted May 7, 2017 Share Posted May 7, 2017 You'll want to put a good size bead, say a 1/4" bead. go on both sides of the blots, it can't hurt. Let it tack up for about 15 minutes then install the pan. If you don't break the bead when installing the pan it should not leak. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it. Engine Build - Click Here Link to comment Share on other sites More sharing options...

06SubLegTx Posted May 8, 2017 Author Share Posted May 8, 2017 Awesome, Thank you very much. The Fuji ThreeBond 1215 Gray, that I picked up was messed up when I got it. I opened it up, attached the plastic applicator, cut the tip off to make a fine bead. As I started to put down the bead, I noticed that the silicone had broken down. Part oil, part gray stuff. I'm no chemist but this should not be happening. If these parts separate it will not cure like it is suppose to, and not bond. I checked the expiration date, it is 08/2017. I thoroughly cleaned the pan off and wiped the pan lip with Lacquer thinner thoroughly. I will get the THREE BOND TB1217H (NEW FUJI BOND) and hope this does not happen. They say it is a bit thicker, but it uses a caulking gun to get a nice steady bead. Link to comment Share on other sites More sharing options...
pseank Posted May 8, 2017 Share Posted May 8, 2017 This is normal. I don't like it either. I knead the tube before using, then waste the first bit. Works great every time. Sent from my XT1254 using Tapatalk Link to comment Share on other sites More sharing options...
06SubLegTx Posted May 9, 2017 Author Share Posted May 9, 2017 Hey, thanks for the info. What do you think of the "THREE BOND TB1217H"? I hear it is a little thicker, and does not have this issue. Link to comment Share on other sites More sharing options...
Max Capacity Posted May 9, 2017 Share Posted May 9, 2017 If it is ok with the oil and temperature it should work fine. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

apexi Posted May 10, 2017 Share Posted May 10, 2017 The fsm says 1217C, but I can't find that, so I wonder if 1217H replaced it. Reading the description for 1217H it sounds like it should work fine.. Then there's also this document from subaru that lists alternate materials if you can't get what subaru recommends. Link to comment Share on other sites More sharing options...
alittletippy Posted May 11, 2017 Share Posted May 11, 2017 Probably a little late, but permatex right stuff grey(import) does an awesome job in place of the three bond. We have used both and have seen no difference between the two. I like that there is no wait time before you install the part and vehicle can be put back into use right away.
