Re: Proper 7.3 oil change
I did not realize it was such a disputed theory. I guess the best way to be sure is try it yourselves. In reading everyones opinions on how the oil should circulate I can understand why people would say BS. Maybe the unfiltered oil that is pumped up top does not drain back in the pan as completely as people think. Three qts is a lot of oil to leave up top. If the oil that is forced through the injectors at a much slower rate then the pump is turning, then maybe it produces a back up(bottle neck) in the system. When engine is turned off the 3 qts will stay up top along with whatever junk is forced up with the unfiltered oil. This would create lots of sediment sludge to accumulate up to without anywhere to go, as it sits in the bottom of the resevoirs. One thing is that the ford mechanics put that plug there for a reason. Dont we have any Diesel mechanics in this crew?
