We just did my exhaust last night and we found the Air Injector Tube broken off the pipe before the catalytic converter. This was not a problem because i planed on installing a off-road y-pipe. We then found the tube broken off the back of the motor. What can we do to cap this off, or has anyone done this.

 

Take off the whole system and plug the holes in the back of the heads.

 

Whats the best way to plug the hole, in the head.

 

IIRC, it is threaded. So a pipe plug that was the same thread would work. Or they may have to be welded. I will check on that and get back to ya...

 

I don't think it's a pipe plug IIRC it's a 5/8-11 NC thread but I wouldn't bet the farm on that

 

Well, the threds were broke off in the cross over tube, so i had a friend just weld it off. and we just pluged all the other vacume lines, and airpump. It worked out great. no more exhaust with the defroster on. thanks alot

 

couldnt find any info on this idea, but id like to run my airpump sytem to my intake "pull in fresh air for reburn" i think it would work but not sure of it. any ideas would help.
