Well when I rebuilt mine.

I replaced everything I thought could ever give me a problem, EVERYTHING.
Now I need an ECU.

does it sound like a loud clock ticking sound

or a have you heard a horse with the shoe tapping in the pavement, only in a really really high rate of speed thats what my rod knock sounded like b4

what does it sound like

does it sound like a loud clock ticking sound?
thats what it sounded like when my friend had problems with his lifters

now, my rod knock on my NA sounded like a horse with horseshoe tapping the pavement or cement,
only in a really really really high rate of speed

If the sound is low pitched and slow, it is a rod knock. It will go away as the rpm's increase. If it is higher pitched (not too high) sound, then it is valve noise. The rod noise will also be a little slower than a valve noise because the bottom end of the motor moves slower than the top end. If it is in between and sounds more like a rattle, then it probably is the wrist pin. This also goes away to a degree with incresed RPM's. However, you will hear it most upon acceleration and deceleration. I believe it is either a rod knock or a wrist pin knock. These are the things that could go wrong in your cenario.

^^actually the top end moves half the speed of the bottom end.
