GX cs4 and cs4-i "squeaking"

Awesome vid. Mine does that and has done it right from the start. Was worried it was the piston/crank connection. Was waiting for it to eventually grenade. Rest more at ease now.
I can assure you that's NOT the case. When I first got my compressor, I opened the crankcase, and all moving parts were well-covered in grease. No squeaks coming from the metal components!
