Pontiac Firebird 1967-2002 - Oil coming out of throttle body...HELP

My first post...I took off the throttle body on my '02 v6 firebird and oil started pouring down the engine block.Why is it doing this?

Check your pcv valve

Ok PCV valve is replaced and I cleaned out the TB (it was all black)I pulled out the MAF for cleaning but it has that black rectangle plastic piece. What do I spray with the CRC MAF stuff?
