I am checking the filter more often than every oil change. It is easy to pull down the oil filter housing, look at the filter. If you want to lose a 1/2 qt of oil you can poor out the filter housing or you can just keep it upright and save the oil. I plan to strap high strength magnets near the top of the filter housing so any metal will be more easily visible in the intra-oil change inspections. Spent $35 for the magnets and I have an extra housing if I ever mess this one up.
