Antifreeze in oil or just condensation! Help!
I was doing some regular maintenance and noticed this yellow substance in the oil cap and just inside the oil filler tube. It doesn't smell like antifreeze. Pics are below (sorry for the crappy pics, no zoom on my cell phone)
Wasn't there when I checked my oil last. Antifreeze isn't low and it looked like there was water in/on the threads of the cap also.
No white smoke coming from the exhaust. Where do I look first?

The last time you checked under the filler cap...was that last week or several months ago? If last week, you could have a problem. If it was a month or more ago, you may not have a problem. Still, that's a lot of crap! I'd at least be concerned while you check for all the signs of bigger problems.
In what condition was your anti-freeze at the start of this cold season? How cold was it rated? Did you have a 50-50 mix? Have you added any to dilute it since it was last serviced?
This emulsion could come from cold weather and short trips. When you don't get your oil and engine hot enough to drive away moisture from the outside air that infiltrates and from combusition by-products, you get this stuff.
Wipe it off. Check the cap regularly. Keep it wiped off. If you don't have any of the usual signs of cracked blocks or blown head gaskets you might take a few trips longer than 1/2 hour at operating temp. Better would at least one long trip. Take the long way home daily for a week. hat will give you a new base line from which to start your observations. At all times through this task, keep an eye on the oil level, coolant condition, filler cap, and what you can see down your filler neck.

Thanks for the quick responses! I checked the dipstick and there was no 'milkshake'. I have been out of town a lot since changing the spark plugs and oil back in late October. Except for the occasional trip to the post office and grocery store it's been sitting.
Gonna keep an eye on it for a couple of days. I have a day trip to central Georgia this week.
Again, thanks for the info!
