can someone explain what is actual making the noise when the timing chain or gears make a knocking noise and sound like a bad rod bearing? The chain slapping and hitting the cover?

I just got it back from Chrysler after theiy put in $715. to replace belt, water pump and timing gears and chain and still knocks! They say it has valve noise but I had a motor with a bad main bearing and this sound the same. sounds like a Allis Chalmer tractor at idle and when you rev it, it speeds up and sounds more like a rattel then becomes harder to hear as the rps increase. then when you let of the gas it you can hear it again. it never goes away it just gets faster so you can't hear it over the engine reving. I shouldn't say it never goes away at one point at idle after running for awhile it sounded good then I drove it and stoped and it was there again.

I brought it back to the dealer I bought it from on Thursday. and they thought it was the timing gears and or chain. They then brought it to Chrysler to get a second opinion. They said the same thing that the sound was coming from there. So they replaced them. i really don't know what was said from one dealer to the other.

they paid all but $225. I wouldn't call it a repair I just went out and listed to it again and it's just as bad. Now I'm thinking or maybe I'm just hoping its the rocker/lifters. is there any adjustment on the rockers? Or how do you fix them if there noisy?
