Help tapping an oil pan

:rofl

Time to shape up or ship out boys!

Keeping it on topic.

right way to do the job:

One of these if you think at some time the fitting size needs to change…

and say one of these to match your existing oil fitting (teflon on the NPT side only)…

OR

if you know that pan will always work with a -XX fitting… something like this welded on…
