    [TD="class: alt1, bgcolor: #F8F8F8"]I recently did a HCI swap and drove it around for a little bit to make sure everything is okay (which it isn;t). Anyway I drove it around and after about 2 miles it was making a knocking/clattering noise. So we took off the valve cover and found out that my roller rockers lockers weren't tightened so my rockers loosened up and were bouncing around. I went through all of them again and adjusted them all again and made sure I tightened down the locking nut. SO after that I started her up again and she idled 10 times better in park. I got in and put her in D and the same clattering noise was back. So I put it back in park and it sounded fine. I revved it up and it sounded great, no clattering noise. After i let it idle down to normal, I put it in reverse for s S%*its and giggles...well to my amazement there was no clattering noise. After in reverse I put it in drive and the clattering noise was back. So I'm just trying to figure out where this clattering noise is coming from when I put it in Drive and I'm at idle?

    Before when the rockers were loose I would rev it and the clatter would get louder. But when I rev it now the clatter goes away (only in drive the clatter happens)

    Kinda sounds like your flex plate might be loose.

    Is it possible for my flexplate to become loose eventhough I never touched it?

    Yeah definitely.
