Should be fine as long as it threads onto the piece that came with the kit, and you can find a tap for it.

I'm not a guru on this, but the 16 refers to the pitch of the tap if I'm not mistaken. It has to do with the threads per inch.

The one I used is 3/8 NPT 18.

That said: I have no ****ing idea if the 16 will be ok or not.

By punching it, the metal of the pan rolls inward on itself. This is what you will use to screw the tap into and make threads.

So you can't just drill a hole. The metal is too thin and you won't be able to thread it. If you did manage to get a thread on it, it would leak like hell.

It shouldn't be hard to find a punch large enough. You start with a small punch and work up to larger ones until the hole is large enough.

I have a regular set of Craftsman punches. I don't recall buying a specific one for this job.

When you use the punch it actually rolls a lip into the metal so the tap actually has enough material to grab onto. If you drill it out there won't be any thing to tap, the oil pan is too thin. Plus you are going to get a ton of metal shavings if you drill it out. Make sure to pack the tap with lots of grease.
