Joe, you said this is a home-made log splitter. I don't have a single problem with that, but I do have some questions. Is the return line really large in relation to the supply line? Have you put a pressure gage in the return line both before and after the filter to see what the pressure drop is thru the filter? Obviously, this is too high, but you should be able to see just how high it is. You might "t" the gage into the line before the line before the filter and then "t" it in after the filter so you don't have to buy two gages. This will tell you the pressure drop across the filter (that's what operates the bypass) and the final reading after the filter should tell you how much pressure the whole filter is under. This is the pressure that is probably most responsible for the filter expanding.
If you have a lot of pressure drop across the filter, you surely do not want to put that filter into the suction line to the reservoir. It would certainly cause your pump to cavitate. I'm not sure what micron size my tractor's filter is, but it is huge and is surely high flow. It has to be on the suction side of the pump.
Finally, what powers the hydraulics? Is it from a tractor's remotes? If it is,
you may have some backpressure through a remote valve that you are not aware of. That could also be the issue with your log splitter depending on how it is plumbed. I would make sure that the line from the filter to the reservoir has no valves and no restrictions in it whatsoever. That would keep backpressure from pressurizing the filter can. Good luck!
