General service thoughts.
Hey all.
I got to go to a class on Fords 6.0 6.4 7.3 engines today. It was a quick general class. What i was shown i would like to pass on. When you change the oil, make sure that you change the filter first. If you dont, after you drain the oil from the motor, you will dump a quart of dirty oil back in the pan. The use of aftermarket filters in these engines would not happen if they were mine. The fit of the filter could lead to dirty oil being sent back through the moter because they dont fit JUST LIKE OEM. The injecter in the 6.4 have real, real tight clearences, and any dirt could stop them if it gets to the injecter. The filtering capacity of the oem is much higher, and has more filter meterial, not plastic. If you run Bio diesel, DRAIN THE FUEL MODULE that is in the frame rail under the drivers door at EVERY OIL CHANGE. If you change the fileter, it will take about five 30 second key on engine off cycles to refill the module. The use of a aftermarket filter is NOT recomended, as a slight design difference could result in trapped air in the top part of the filter and not only is just half the filter being used, but the filter meteral does not have the filtering the OEM does. RUNNING a 6.4 out of fuel could bust the injecters as they need the fuel as a coushin for the pintel slams down. Fuel lines on the injecters MUST BE REPLACED IF THEY ARE LOSEND UP OR REMOVED. New lines are in the injector kits. Some of the ford techs here can add to this, this is just what i picked up in a quick class, and thougt i would pass this along. CJ-4 IS REQUIRED, IS A MUST IN THE 6.4 MOTOR. CJ-4 can be used in anything down. They said synthetic oil, should not be used to go longer times between oil changes synthetics are ok, BUT CHANGE THAT OIL ON TIME. Happy trucking folkes

not to play devil's advocate, but was this a OEM filter/product sales pitch class? there are some quality filters on the market that are not oem and some that are worse.
those issues are very generic to any diesel, especially the mention of tolerances within fuel injectors.

No, it's not a pitch. I run a fleet of SD's ranging from gas to 7.3 and 6.0 F-550 bucket trucks. Ford and Baldwin fuel filters have a special media on the fuel filter that helps keep the water in the framerail filter. It's a plastic mesh that won't let the water through. Compare a wix/crapa filter to the Ford and you'll see. It also has a check valve on top to let air bubbles out of the filter.
Oil filters on the 6.0 are tricky. There is a slight height differance between the OE Ford and aftermarket. It's enough of a differance to allow the oil to drain back into the pan if the truck sits for more than a day or so. You'll have an extended crank to start, because the oil will have to flow back to the filter before it can go to the injectors. Which allows unintended wear on on the injectors.
So far I have'nt found an aftermarket filter that won't do this. We are contemplating swtiching all of our filters to Ford to keep from breaking down our injectors on the 6.0's. They are a PITA when they are "Working Normally", the last thing they need is another reason to break down.
