In addition to using Jalopnik to answer any car questions I may have, I also depend on Brazzers for relationship advice.

Me: Any other thoughts?
Brazzers: Hmm. PIITB?
Me: Right.

A person really should keep the rpm's low, as the differences in oil temp, and the way that the piston and cylinder heat up all contribute to bad things happening.
Not that a person should let these idle up to a hot temp, but having them sit around for a few min isn't the worst thing ever, gives things a chance to get used to moving again and the oil a chance to flow.

The biggest mistake people make is firing the car up in winter and allowing it to warm the cabin before they get in, or allowing too much engine warm up time at idle. This keeps the cold start, and just started enrichment higher and for a longer amount of time. All the while the injectors are dumping excess fuel to help light the catalytic converters off, with help of secondary air injection. This fuel is pure solvent, washing down the oil thats the lifeblood of the cylinders and pistons.
Load= Heat. Get in, strap in, fire up and drive away lightly and the engine will not see nearly as much over- enrichment.

For more bore scoring scares read one of the more recent threads. To warm or not warm, that is the question.

Here is one data point that refutes the theory that the car is not warming up enough, or driven enough as the cause of the white/yellow substance.
My 03 C4S is a daily driver in Chicago.
My commute is 37.5 miles each way at highway speeds (high speed highway speeds). It gets fully warmed up every time I drive it.
I have the yellow/white gunk.
I think it is more of a function of winter driving and the fact that the oil inlet tube is so removed from the engine (and plastic, an insulator of heat). The water condenses overnight in the cooling engine. When driven, the water vapor comes out of the oil and condenses on the cool oil inlet tube and cap.
This summer, I'll see if it makes a difference, but it might not since the cap and inlet tube will still be much cooler than the engine.
I'm not worried about it at all though.
What a great car. I'm having so much fun driving it every day. (I've only owned it ~~5 months.)

confirmation
I can confirm that my oil inlet tube looks 100% clean now that I am driving it in the Chicago summer season. I'm driving the car in the same manner as I do in the winter (of course I drive differently when snow is on the ground).
All winter there was that yellow/white gunk. Now I've checked several times since the weather warmed up and it is perfectly clean.
