I guess I might chime in a little. It wasnt the alternator squeek the first time. The sound is totally different. And Yes i did talk to precision machine and they said it was something in the Heads. I wouldn't have any one other than Cody work on my trucks bc he knows what he is doing. He canceled his vacation to Phoenix to come do my head swap, lost money on his flight and everything. So he obviously thought it was something really wrong. But hey its gone and the truck runs great.


ooohhh btw the alternater quit squeeking.
