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

............and BTW........those stock rubber type gaskets dont last forever......when you pull the TB off replace the gasket .......you will thank me later
