Default Yellow Sludge - Throttle Body - Cause!?!?

Howdy,

In the middle of a cam swap and pulled the throttle body off to get the water pump out and found this!




Theres nothing under my oil cap and no residue in the oil pan (well there wasn't when i changed the oil about 500 miles ago). What the hell could cause this? Should i be worried about a head gasket?

Thanks,

-Karl

How cold is it and how far do you drive? Issue is likely the cold weather and short distance driving. Contributors are low temp thermostat and altered PCV system.
