And we're having that conversation. But it's been sidetracked (ever so slightly) because you took offense to Jerry's choice of words. HIs advice is rock solid. What he's saying to you is that sometimes, modifications tend to make things worse, not better. Some pretty intelligent people designed the engines that we deal with, and it's always wise to consider that they might have known what they were doing, even back in those olden days.
My 235 has been modified to use a spin-on filter, but that's because it had no filter at all when it came from the factory. Some filtering is clearly better than none. But, as Jerry points out, you already have a very good filtering system on your engine. Modifying it for a spin-on filter would make it
less effective. That's what Jerry's trying to tell you.
Don't take offense. Take it under advisement. That article you referenced is one man's opinion, and it's quite dated. Now you can balance it against Jerry's, and he has a wealth of experience.
