I just bought a 2004 f-150 with the 5.4, 3v, with 60k miles. The truck runs like a top, clean carfax, prior owner reported no problems and local Service manager ran the vin on Ford's system and found only a minor recall for a check engine light when the truck was 3 months old. Before buying, the oil looked good on the stick,but when I changed the oil and pulled the filler cap on the valve cover, it was full of "cream" indicative of moisture in the oil.
I have seen on another forum that short drives (wife drives about 4 miles, one way, to work) in cold weather, the engine does not generate enough heat to cook off the condensation in the engine. The oil from the pan did not show any indication of water.
Is there a solution to this, short of having her drive 12 miles out of the way to work just to build heat?

The truck just wont climb a hill. Downshifts and slows down to about 30mph.
RPMs never go over 2500 to 2800. Even when I pop it in nuetral - no more rpms.
I have to nurse it from a stop to about 50 on the flats. If it starts to loose speed it will downshift and go even slower. Can't pass anything if I try it downshifts and revs to about 2500 and slows down. Dont think it is a tranny problem because if I throw it into nuetral the rpms dont go up or go up very slowly. The engine idles fine and does not have a miss. Help

Before you assume this is some kind of condisation. You may have the beginings of a blown head gasket. Lets hope not. Or, there was a blown head gasket prior to you owning it and that area was never cleaned. Anyway if this is just some condisation that builds up and leaves a oil water mix just in the oil cap area. You might try an after market breather. As far as cleaning it out, just use some carb cleaner spray. It wont' hurt anything and will eventually evaporate.

hey guys i'm having problems with my truck. I turned right today an it shut off. I figured it had overheated which it did but now it won't start. It will turn over but it won't fire up. I'm wondering if this is an gas problem or if there is something wrong with my engine. any help would be much appriciated.

After checking everything else I found out it was my Cat converter. It was totally clogged.

Have the truck diagnosed (any auto parts store can check for errors). My guess is that the oxygen sensor in the exhaust on that side, which will make it run rich.

Was the converter clogged from bad emissions, or did animals (mice, etc) get into the exhaust system with nesting material or food?

The ceramic cone was clogged. I was gray in color instead of off white. The million little holes were almost all closed. I was told it may have over heated.
#77 of 252 5.0L heavy on gas

My 1989 5.0L F150 has started to use a lot more gas then before. It is running fairly will but blows a little black smoke and smells slightly rich. cats are new. top half of engine has been rebuilt (was running rich prior) has only one sensor on exhaust. engine runs at normal temp and only slight increase under heavy load. gas useage has gone up by almost doulbe. engine does not use oil and starts first turn every time. can not find any vacum leaks have checked when engine is first started from cold. all new plus wires and filters. Uses same amount of gas under heavy load and with no load.
