Clattering noise when put into drive after HCI?

Kylebach14 · Apr 16, 2014

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)
