I'm new on here and am gonna continue this hijack a bit. I have a '98 E-350 V-10 Club Wagon and I get the same thing on my oil filler cap. Am I correct to assume that this is the same engine as the '99 F-series?

You'll see a coating of slime on the filler cap and inside the filler tube. It usually indicates water in the basement. Could be condensation or coolant. If you're losing water, it has to be going somewhere. (Sorry to say) Coolant doesn't just disappear. That is a great way to check out a used car if you happen to be shopping. Most dealers/owners aren't smart enough to clean it. It'll save you A LOT of $.
You should be able to put a pressure tester on the cooling system and see if the pressure bleeds off, check it hot and cold with the engine off. You can also use the tester and see if the cooling system builds pressure too fast (usually indicates a bad head gasket) while running.
I had some condensation in my 99 V10 when I bought it. I changed the oil and drove it hard for about 100 miles. Got rid of any sign of water in the oil and is doing fine now.

I wonder if maybe we should start another thread on this "snot" issue. My 2005 runs perfectly, but the inside of the oil filler cap does show an abundance of a light tan "snotty" substance when I use dino, though I don't believe it does when I use synthetic.
Why do you believe this is water related?

I had a 99 and I only had the "snot" was I was making alot of short trips around town. After a good run on the freeway it would clear up, I think alot of people see this one thing and think to much of it.

From my experience with my fleet trucks it's a sign of problems yet to come. Without a doubt the rigs that have the snot eventually end up with a bad head gasket/cracked head. Mostly in the diesels.
The freeway trips get the oil hot enough to burn the water out, that's why the snot goes away. I wouldn't tare a motor apart just because I found snot in the filler, I just use it to make me aware of problems that might be coming.
