a6 bottom end w/ y8 head w/ aem cam gear and y8 timing belt. The belt keeps moving back. i tighten up the tensioner bolt as what the manual says and it stills moves back. i aligned the crank pulley and the cam pully already too and when i put the timing gun on the timing is still off. i cant advance the dist any further either. should i drill the housing?

 

that belts too large. you need a d15b7 belt from a 92-95 civic dx or lx. trust me, i know. also you shouldn't have to advance your dizzy at all, put it back dead center and then get the correct belt. make sure your cam gear is set 4.5 degrees advanced also for the y8 head
