OK, now I have read this whole thread. Brad, you have made some very good points[yes, I believe in giving credit where credit is due, even though we don't normally get along]. I have not been familiar with by-pass systems before. The old 235 Chevy engines had a by-pass system on them, only without a full flow filter at all. Those oiling systems aren't that good though as the by-pass system just ties into the main oil gallery. Most of the oil still just goes into the bearings, so I don't see how much help that system is to those engines. I have one of these 235's at work right now, and the bearing journals are really scratched up from dirt. Really bad. But, who knows how that engine has been managed.
I think I am going to look into one of these systems for my engine when the time comes. Makes a lot of sense. You still have the main filter to catch the big stuff, and the by-pass to keep it all clean for a long time. Seems win, win to me.
So, how much do these systems run?
