One thing I want to suggest to anyone changing there own oil with a Ford 6.0 PSD. Only Use Motorcraft Oil Filters! Some Fram and other manufacturers DO NOT HAVE ANTI SIPHON VALVE. Without this valve oil can siphon back to the pan leaving the top of the engine dry for your next start. You will not have any signs anything is wrong initially but damage will take its toll and Ford will want to see receipts for your oil changes if you are under 100K warranty and have issues. If you are using a filter without anti siphon valve……you will likely hear Sorry. The problems could be many as this engine relies on high pressure oil to fire fuel injectors and a high $$$ pump that feeds the system sits on top of the engine (inside) will eventually go more than likely taking $2500.00 worth of fuel injectors with it. I do not work for or represent Ford I am only a 6.0 PSD owner with something to share.
When I took the Motorcraft oil filter out and compared it to the Fram, there was no difference, and there is no anti-siphon on either filter element. On the 6.0 PSD I have, the filter assembly is on the top of the motor. When you take the cap off, there is no oil in the filter cavity. According to the manual I have,
If there is a difference, please provide pictures showing the anti-siphon valve.
