Concerning the new oil pressure relief valve install, DIY articles suggest a loss of 0.25-0.5 qt of oil after removing the bolt, so I was prepared with a catch pan. This only applies to unmodified oiling systems, as I learned...

When I removed the bolt, well over 3 quarts of oil came out and kept on going before I put the bolt back in. I believe this was because I have an Accusump and a remote oil filter, but can anybody explain this!!! How could this happen if the full flow oil filter still has an anti drainback valve? Or is there something else I am missing?
