The paste is condensation that builds up in the engine. It won't hurt the engine (as far as I know), but it tends to happen more in the winter, and is the result of the car being used mainly for short trips. I get it all winter in my car (97 Accent).
The paste on the oil cap can also be produced when you hit the throttle(too much)and your motor is still cold.Drive around for 10-15 minutes and then race your car...If you do that youll never see paste again on your oil cap<img src=/images/forums/snitz/wink.gif width=15 height=15 border=0>
Paddy,... come over to Hyundai-owners.com (not taking any steam from the Cru) but we'd like to have more Winnipeg Hyundai owers getting to know each other. Anyway, that's the old site above, and we're revamping our site now, it's hosted on my MTS account, new site is http://www3.mb.sympatico.ca/~camktran/
Once we're done revamping, it'll be on the Hyundai-owners.com url.

I always thought paste on the oil cap as you described it was NOT a good thing. IE Moisture in the engine whould could lead to hydro-lock or indicate a head gasket leak or some worse. (What is worse?) Anywho. I remember when looking for a new (used) car all my buddies (mechanics, wrench heads, grease monkeys) all wanted to check the oil cap to look for "ice cream". <img src=/images/forums/snitz/oogle.gif width=15 height=15 border=0>

I am a tech at a chevy dealer. All cars experience this like others said it is condensation the is produced inside of the crankcase. It will and can not harm your engine!!!!!!!Even new z06's do this!!!
Wanna make sure, pull the dipstick first thing in the morning and check the quality of the oil. If it looks like a milkshake or is "spotty" you're in trouble. If the oil quality is fine, then check the condition of the oil-cap seal.
