aluminum works, but i have found over the years working with aluminum recessed hex plugs, that all hex wrenches are not created equal. and when the wrench doesn't fit EXACT, the hex strips, or rounds out, causing me lots of grief removing them after the fact. i prefer steel or brass for just this reason alone. stainless plugs are good, but you have to make sure the threads are coated with something that will prevent galling. if you don't, same grief applys. just my experience and preference.

All good points. And the port must be drilled and taped. So why go to all that trouble when you can just tap in the core plug? Pipe plugs are a lot more trouble to install, can be a problem to remove, and do not any better job.

If I went the core plug route, what do you recommend tapping it in with to tap it in even? Do I drill the 3/32 hole before or after the core plug is in place?


I use a small 1/4 drive socket that fits inside the plug on a short extension to tap them in. That way I don't dimple the tranny case. It doesn't matter how deep you go with it as long as it is past flush with the case. And it doesn't have to fit very tight because it is essentially trapped and cannot go anywhere.

I drill them after they are in place. It's just easier. Grease the drill bit to catch as many chips as possible and then use the straw to spray brake clean or carb cleaner or the like above the plug to wash out any surviving chips.

Have done quite a few that way and have never had a problem.
