So, Its defiantly not coming out of the vent. 
Degreases/Cleaned it up good, then took it around the block (10-15) miles, this is what i found. 
It appears to be coming from this plug and somewhere at the rear seal or the bottom/back of the housing. 
	
 
	 
	 
	 
The SYE leak really appears to be the output yoke seal. 
Im not 100% sure i put silicon on the splines but i know it put it on the rubber washer when i installed the yoke and torqued that bitch to 150 ft. lbs. 
	
 
	 
Mhmmmm - RUSTY.....
