Primary leak making me nuts!
Lookin for some advice from you guys. My primary inspection cover keeps seeping, from the last fluid change and now again with new fluids and another new gasket. I have forward controls and the mid control stuff has been removed so it's just an HD cover on there.
The damn primary drain plug loves to drip too, any tips to stop that? Thanks

Uneven mating surfaces that the gasket can't compensate for ?
For the plug, maybe a small application of teflon tape. I say that, because obviously the threads and sealing device are not doing their job. That and if a little teflon gets in the primary case, no big deal. Wouldn't recommend it for engine applications though.

I put teflon tape on the drain plug bolt and a new o-ring and it still drips.

Like mentioned, take a close look at the shifter shaft plug/hole.
Not sure if you can get to it, but I would check for cracks around the plug hole also.
If you sand the insp cover surfaces, make sure you use something like 330 or finer, and a block to sand with.

its probally the inner primary shaft seal... oil runs down the back of the primary and drips off the plug

Use a small mirror and flashlight, look up to the shifter shaft that goes into the transmission case. Any oil getting past the oil seal will go right to the plug on the bottom of the primary, thus making it look like the plug is leaking. If thats not the case then there may be a crack in the primary case where the drain plug goes in. The plug is a tapered pipe plug going into a straight tapped hole. The fix for the oil seal requires the inner primary case to be removed and most everthing in the primary, sorry for the doom and gloom.
