Drilling and tapping the oil pan seems very iffy. Drill/tap into the pan, let the metal shavings fly and hope for the best? You could drop the oil pan (although the installation instructions don't specify that). But how many installers drop the oil pan?

I don't think ESS requires tapping the oil pan. However don't know what they do instead.
I think they use a modified dipstick.
