Nice of you to oblige them (though hopefully only infrequently :rolleyes:).

I got to looking at the specs for the filter I’ve been using (51042, on the right below) vs the one stevedOx linked (51348):

I noticed that his specifies a value (8-11 PSI) under the section labeled “By-Pass Valve Setting-PSI” whereas the one I’ve been using indicates “None” in that space. I don’t really pretend to understand a lot of this, but does that “None” indicate a lack of bypass at start up (ie a good thing)? And that my setup with the 51042 is preferable to that with the 51348? Or am I totally off-base on this? Educate me, please ;)

No bypass means 100% filtration 100% of the time; no unfiltered oil, ever. This style filter has been used on several high output factory engines for years without issues.
