I went to the dealership today for the recall and also to see if my manifolds were cracked and first the guy looked at me funny and said i doubt that is what it is.Once they took my truck in for the recall,they were back within 20 minutes and said well i'm sorry you were right 2 cracked manifolds.I wanted to laugh in his face but since he said they will replace in a couple weeks free of charge i just couldnt do it.Not a bad day at all.I read all of you guys input on the cracked manifolds i knew that is what it had to be.Thanks Titan Talk!!
