A Mopar crank bolt washer welded on a pipe is the perfect cam plug driver for a BB Mopar--drive it all the way in--you can even use two if you want to make sure and keep that clutch dry--I have always used Permatex #2 on freeze plugs, but usually use ultra black or ultra grey on the cam plug--they are the most oil resistant of the RTV family by far--you can even JB Weld the cam plug for that extra touch ( this step reserved for those who actually had one leak in the past)
