It looks like it was the lower tailhousing bolt that was actually leaking. I drained the case and sealed the bolt threads and cut a gasket to go under the bolt washer. I re-filled the gear oil yesterday so I should know in a couple days if that did the trick.

Thanks

So Dan, did it work?
Here is my situation. I thought I had the same problem as you with my Toploader. I tightened up the tail shaft section but they were already very tight. now that I have the interior out including the tunnel,l I noticed the top is wet and it is seeping from there! I snugged up the bolts, they were not tight at all.I would like to install a new gasket. Is this as straightforward as it looks or is there a surprise waiting below?
Does anybody know the part number for the Gasket I need. Also a Torque spec for the bolts?
Thanks...Dave

I thought this was going to be some hard to find part for some reason. Easy find thru Google. It is Fel pro TS-13405 for the whole gasket set.
Now I just need the Torque figure for the bolts? Is there any sealant I should be putting on this gasket or just the plain gasket?
Dave

Dave - My top plate still leaks after re-sealing a couple of times. I straightened the lid flanges and basically tried re-sealing the original gasket. Still seeps not unexpectedly. Sometime I need to try a new gasket. You wouldn't think it would take much to keep 90 wt gear lube from leaking - but it seems to always find a way. I would use some sort of gasket sealer/dressing but I'm not sure what would be best. Lately I've tried Permatex Fuel Resistant gasket dressing with good results. Seems to work better than Permatex #2. Not sure if just lucky or really good stuff.

At least one of my shift fork seals is leaking also. I put leather gaskets behind the levers too slow it down (which it did) but still get a drop now and then.
