that would prolly be a rod pinging the block during travel. It will get louder.

id say rod bearing, if the rod was hitting the block, one of them would have been in pieces already

i can rev the car up but the noise doesn't get any louder it stays steady.

The day before it was nocking like every other minute only when it wanted too, but today when i turned it on it was a diff story.

its a rhythmic knocking in tune with engine rpm, knock, knock, knock? Does it escalate with rpm? If so its a rod bearing alot of times. There easy to hear a mile away

sounds like the knocking volume stays constant, but as you rev the engine does the the speed of the knocks get faster as well?

Sup bro i think its on the right side drivers ...tomm i work but my dad and uncle are towing it to his house and will tear it apart to try to figure what the hell is wrong with it. My dad put it together so he should have an idea on what it is, he suspects a pushrod or something having to do with the rollers...

a knock is far different than rocker ticking, which is it?

Well started her up today with the covers on and she started making that damb noise again, but we used the old hose to ear trick and figured out the problem(water pump) she went bad. We removed the belt and the noise stoped so the knocking noise was the water pump screwing up.

stupid car so now i have to wait for the ups truck to get it running again...
