i cleaned off the yellow oil cap on my car last time i changed the oil in ie... 500 miles ago... and noticed a yellowish colored slime on the bottom of it. i checked the oil when i drained it and there seems to be NO anti freeze in it. There also appears to be No oil in the overflow tank so all the seals seem to be keeping the oil where it is supoosed to be and so are the seals keeping the antifreeze where it is supposed to be. Any ideas what it could be... should i worry about this?

Thanks

don't worry, it's normal.

So it is normal? Then what is it that causes the tan deposits?

the stuff on the cap is a water/oil condensation that is formed from the engine not warming up enough to burn it off, ie, short trip driving, esp in cold weather.
