Check your oil level. Could be the lifters not fully filling with oil and tapping against the push rods. Just a guess though.

Left a 421RWHP 2004 GTO, but honestly loving the G6 GT coupe!

Past Pontiacs
87' white Firebird(sold)
01' green Grand Am SE2(traded for the 03')
03' orange Grand Am SC/T(totaled)
04' blue GTO(traded for the G6)

Current Pontiacs
00' tan Montana(I swear, its the wife's)
06' black G6 GT Coupe

not really coming from top of motor. sounds like it's coming towards the wheel. when you first start it up and get out you can hear it down towards the wheel. maybe it is the a/c compressor

the compressor runs quite a bit actually, the only way to truly turn it off is to turn the HVAC system OFF, not something I do often
