I know you guy's have talked about this some where, I noticed that a strong ticking sound up in the intake area. I'm wondering if the wrist pins are doing this or it is the rockers. It sound like more than one, but it does have 173000 miles on it. Is it time to get a long block or this a week end job????? - - - Updated - - - After reading simular threads, which was located at the bottom of this post; Seams to be a problem in these 6.0's.. Now do they or have they come up with correct way of correcting this problem??
