jarroyo

I began to ter down my motor today in an effort to replace all the vac, coolant, and fuel lines that may have been neglected over the years. Once I got the throttle body off I noticed a moderate amount of oil on the rear side of the butterflies. Is this something I should be concerned about or normal for an FC? Thanks in advance.

Oil, or oily buildup? If it's just dirty gummy crap, it's normal. It's just the fumes coming from the 'crankcase' vent building up. A little carb cleaner should get it off.
