[QUOTE=BYprodriver]Awesome writeup & photos Brad, thanks for posting this. The AOS for my 2000 S did not come with a O-ring just sealant on the tube, do I need the O-ring also to seal the tube going into the block??[/QUOTE
Pulled the original out of the trash & realized new AOS -04 version has improved seal on the tube & original had single O-ring.
