Oil Leak Coming From Transmission Tunnel

And bam, you solved the problem! Teflon tape is good on the pipe plugs. The cam plug is shallower than that one. I use Indian head Shellac on all freeze plugs.

Thanks for your help! What do you mean by "The cam plug is shallower than that one." Aren't I supposed to knock it in flush with the block?
