Tapping the dipstick hole? I don't know why people always insist on reinventing the wheel. I've never in my life had trouble with a dipstick leaking where it presses into the block. Put a little sealer of your choice on it and press it in.
It was just a thought I expressed Rusty Rat Rod, Was wondering if anyone had done it , that's all. Not trying to re-invent anything. Be a piss poor hobby if everyone left things the way they left the factory and didn't try mods. !
