I just placed my filter in my parts cleaner and reversed the flow. I let it run for a couple of days. I then let the filter drain.
After that i placed a plug in one end and filled it clean oil and let it sit for a few hours, i drained the oil and refilled it again. I did this 3 or 4 times. I know that this process may be risky but i guess any filter is better than just by-passing the filter.
i also have been changing my oil every year and my best estimate is that i have less than 1,000 miles a year.
