96 Rodeo: loud..rpm but quits ony under certain higher torque

Customer Question

There is a very loud chattering coming from My 96 Rodeo 3.2v6. It corresponds with rpm but quits ony under certain higher torque/rpm conditions. I've tried using a tube to find source but it sounds like its coming from the block area ...possibly the timing belt area? I was told it might be hydraulic lifters which had been making light chatter before this noise. Timing chain/belt replaced 30,000 miles ago.

who told you lifters
Customer: replied 8 years ago.
A customer who owned the same model said that the hydraulic lifters will make noise and are not adjustable. I was accelerating into merging traffic, hit a pretty good size bump and all of a sudden the clattering began. I doubt the bump would cause internal problems and might be related to the sudden acceleration. The noise disappears both in neutral and drive when reaching 3500-4000 rpm and above.

do it sound as if it could be starter tapping fly wheel
Customer: replied 8 years ago.
The starter was replaced 3 months ago so thats a possibility. Would this be a bad starter or a loose bolt, or a flywheel problem. I've never heard of a starter doing this but I guess that's a possibility. Why would it stop at higher RPM's?
Expert:  Trouble shooter 1 replied 8 years ago.
being under loud could cause it to stop but the start can stay retracted not all the way but some ift could be a loose bolt or just bad stater motor
Customer: replied 8 years ago.
I will go under the car to see if I can listen to starter/flywheel area with a tube. I still don't understand why the noise would disappear under higher rpms.
