I for one could use a re-explanation on what you said:
"Uses a 3/4-16 non-bypass filter. Can use the Toyota/VW PH3614 sized filter, or if there is room, the Ford/VW PH3600/PH2870a. Don't rely on the OE bypass valve. Its usually varnished/sludged seized and useless leading to issues common to all the Datsun/Nissan PH3682 engines."
"The PH3614 and PH3600 have a bypass and are better choices."
Are you saying the 3682 has no bypass valve, or that the 3614 and 3600 have better bypass valves?
Actually, I started searching and found this old thread:

How do I know if the 1.6 in the Sentra has a an internal bypass on the engine block? I'm assuming by your answer that it does not, but how does one find out this information?
Thank you, sir.
