Hello, I just changed my oil a few days ago and my 2008 4.6 L F150. I literally do all my own oil changes been doing it for years routine oil change nothing weird. I have noticed for some reason after this oil change I started smelling a smell of burning oil while driving after a while. Because of this I checked my oil, and I am indeed leaking oil because I just changed it and I'm lower than full. The weird thing is I have no drip anywhere. It is not the filter it is not the drain plug or the drain plug gasket. There is some lose oil that's on a hose that runs in front of the oil filter, but I figured that's from where I spilled it when changing the filter. Any help is greatly appreciated

If you've only checked the oil level one time it might be that the "missing" oil went in to the oil filter. Your first guess is probably right and you just spilled a little and it's made its way to somewhere hot. Check the level several times and be sure it's actually disappearing.

Also, as I understand Ford's fill advice, they recommend only adding oil when the level drops below the range. Apparently, damage from over-filing is worse than damage from running under for a short while. So, no need to top it off it's not at the high end. Just make a note of level, and monitor.

Foaming etc from overfilling and hydraulic pressure on seals not good . You need to surround your oil fill with rags/ paper towels and use a funnel to fill . I once spilled some and it went into a alternator ruining it $$$$. Never again .
Yes you need to check your level several times after changing and running . Unlevel ground ,temperature etc . I preload my oil filter ,
some say you shouldn't but hey I fix my own stuff with my own money and I don't like the delay in oil pressure while its filling from oil pump. . I keep a funnel and rags in engine compartment for top offs so I don't have to hunt for one and I clean funnel before using . I always carry extra syn oil in case it goes low ,these engines burn oil .
Debri in crankcase can slow the filling of oil filter and flow rate such as broken plastic guides pieces and sludge blocking oil pickup screen .
Always look for leak around oil filter after change .

I preload my filters and have never had a spill. I preload the filter at the start of the project and lay it aside. By the time I get to putting in the filter, the oil has soaked into the filter and none spills out. I am sure you could put so much into the filter it would spill out, but even then, not much. You can keep a slight tilt up on the filter right until it reaches the contact point and then screw it on quickly.

Its no worse than the oil taking it out . Oil is like blood you are going to lose some . Ask any of us old guys with paper thin skin .

My luck, I'd drop the pre-loaded filter on my face.

4.6...Isn't that filter straight up and down?

Regardless, do as others have said and check it periodically. My bet is spilled oil. Simple.

Not on mine, but my 4.6 was built in the Windsor plant and uses a different size oil filter than most 04 4.6's too.
