Can you add an engine oil filter on some BnS engines?

[Poodlehead]

I have what looks like a cover on the lower left side of the engine. I was wondering if that cover can simply be unscrewed and replace with an oil filter? M/N 4076770 258E1

Thank you in advance!

You can unscrew the cover if it is the one I think it is and then install the 690954 oil filter nipple, and then install your oil filter.

It must be the one you think it is because it looks very unscrewable. I'll get the nipple and oil filter for next oil change and report back.

Hmmm, any idea if it's standard pipe thread?

Thank you!
