Motorcraft - Oil Cap - Dsl P EC781

I received an authentic Motorcraft oil filter cap. If you own a 6.0 Powerstroke, it is absolutely imperative to use only authentic Motorcraft caps for the oil and fuel filter housings. Other "will fit" caps may seem the same but due to infringement laws, they cannot exactly copy the OEM parts. This leads to more oil going through the filter bypass which goes back into the engine without being filtered. On the 6.0 Powerstroke (and to a lesser degree the 7.3 Powerstroke), clean oil is directly correlated to engine longevity due to the high pressure oil pump (HPOP) system and fuel injection system, both of which are very sensitive to dirty oil. Bottom line is that do not cheap out on filters and their associated caps on the 6.0 Powerstroke! Also, this cap is the correct cap for the horizontal fuel conditioning module (HFCM) on the driver's side frame rail. Read more

I have an 03 f350 with a 6.0, my hfcm cap(the fuel filter/pump assembly on drivers side frame rail) got damaged plastic cap nut rounded off and i needed a new one. I looked all over the net for a p/n and nothing came up. finally i stumbled across a forum that said the oil filter cap is the same as the hfcm cap on the 6.0. So i bought it, it fit good threaded on fine, no leaks, the 40 nm(18.5 ft/lb) torque spec on the cap matched the instructions for fuel filter installation, conveniently same as oil filter cap spec. It comes with a black oring for the oil filter assembly would probably work fine, but if you have it apart you probably are swapping filters anyway so they will come with the correct green oring. I would caution to either buy the oil filter socket for these caps or at least use a six point socket(36mm), don't use the 12 points since they will gradually round off the plastic. Read more

Definitely on the 6.0L Powerstroke, you need to use the OEM filter and the OEM cap. Not a good idea to go aftermarket, but if you're dead set on aftermarket, each to their own. I've been a diesel mechanic for forty years, some things aftermarket work, and some don't. This is one that is not a good idea, stay OEM. Read more

I word of advice... Use the OEM oil filter, I don't care if aftermarket has gotten better for the 6.0 over the years. If you spend the money to have someone do your oil, take the motorcraft filter with you and insist they use the OEM filter. I bought this when I seen the owner before me used a aftermarket filter. YES, this is the same cap for the oil filer and fuel filter on the frame. Read more

Appears to be OEM. I used to KNM filter with it. Fit great. Would recommend. Read more

If you're having problems going through IPR valves and are running a aftermarket wix filter, that's your problem. Get the wix out (even if you're not having problems) and go with the factory motorcraft filter. Yes the wix is just as good as the motorcraft filtration wise but it doesn't fit the canister correctly and will allow oil to bypass unfiltered(there is a Ford TSB about this problem) Read more

Working great Read more
