Sounds to me like your pcv valve has stopped working. It is easy to check, just pull it out and shake it. If it rattles it is probably ok. But while you have it out go ahead and wash it in solvent (or kerosene), make sure it rattles with a good rattle sound (if that makes any sense). If you cant get it cleaned, buy another, they are cheap. Let me know how it goes.

This is a sign of water in the crank case. I would make sure that you do not have a cracked head or a blown head casket. alex

Everytime I saw creamy oil it was a blown headgasket (Anti-Freeze in the oil).

#179 of 252 2001 F150 5.4, idles low or shuts off? by xelvis66x

Jan 25, 2010 (5:54 pm)

Since it got cold this winter the truck will start up then shut back off, unless you touch the throttle. As soon as you leave off it stalls, no idle. After it's run awhile to operating temp it usually run ok. No codes on my scanner. I tested the TPS with an ohms meter, and it icreased smoothly not eratic. Any suggestions, thank you!
 
Also, it has 103,000 miles and we keep up on the maintance. This is the first trouble we have had. This truck is usually sitting and used for hauling, and some trips etc.

this happened to me also, I drive a 04, F-150 with the 5.4 3 v. It turned out that the ETB on the throttle valve intake was the problem. Alex

You were a little unclear if this creamy stuff is re occuring on a regular basis or not. There are a number of possibilities;
 
(1)Moisture like the oil changers said. Ford trucks do this a lot.
 
(2)Blown head gasket or micro crack in cylinder head or block.
 
(3)PCV valve faulty
 
If some moisture just got caught up and mixed with the oil over time, your Ford does have a reputation for this. Buy a bottle of liquid not spray Berrymans B12 carb cleaner (pint) and poor into where the oil goes. Drive arround for at least 40-50 miles and then change your oil. Wipe the excess creamy stuff of your cap.
 
If it is a blown head gasket there is a product called Blue Devil Block Sealant availible at NAPA. The thermostat has to be removed and you have to follow the instructions on the bottle, but it works real well in sealing blown head gaskets and cracks. Pay a mechanic that has done this before. I have a 98% sucess rate with this product on vehicle that will run for at least an hour even though they have a blown head gasket. On vehicles that have a blown head gasket but do not over heat, it has worked every single time, 100%. Good luck!

This truck doesn't have this part. The manual only goes to 2002, so they must have started the ETB in 03. Thanks!

If the oil is creamy or yellow and the oil level goes up usually thats when there would be a blown headgasket, or like you guys said before a cracked head, or waterjacket would do this also.
 
When you checked the oil was the level above full, and were you low on anti-freeze? That will tell you if the headgasket blew. That happened to my brothers jeep, he replaced the gasket and his levels are good and the yellow is gone in the valvecover.
 
I hope this will help?

#184 of 252 91 f-150 4.9 engine problems by raspy

Jan 27, 2010 (1:02 am)

91 f150, 4.9 I6 w/5 sp -187000 mi.. over all truck runs good for age and milage.BUT! when truck is allowed to warm up a while you go to drive it and after 5 mi. or so it will start to miss/bog down like its dropping spark or losing fuel. if it stalls it will not restart right away. and it doesnt always do this either. usually a couple days in between. the first time this occured i opened the hood and found the ps pump cap loose and it had sprayed some fluid on the coil and its connecter clip. a few dayes later i put new plugs cap rotor. made no difference but i did notice the distributer was extremly loose and was out of time. i reset by ear which corrected the loss of power ive had ever since ive owned the truck but has had zero impact on the running crappy and stalling issue the local shops wont touch it cause they say it has to be not running for them to find the problem but when it dies by the time i get it in town to the shop it will restart on its own. Any advice on this matter would be greatly appriated
