Yep. It the O-Ring don't work I will just use some RTV on it and hope it will work along with checking the lower intake while I'm in the general area. Also I did some calling around and found a machine shop that can pressure test the lower intake along with checking it to see if it is warped. They said if it is warped and not cracked the can machine it down to make it true again. Also if it is only warped I will have them hot tank it along with getting the upper intake hot tanked to get rid of all that carbon build up.
