started doing it over 12k miles ago. Its progressively getting worse.

 

it sound rough were u reving it or is that wut the problem wuz. it sounded like u should gap ur valves tho the cacking itll givv u sum lost hp too. .010 gap get a feeler guage nd the little valve cover gaskette pack at autozone

 

Thats how it sounds like when Idle and when reving. The sound stops once I go pass 2000 rpm.

 

try gaping the valves sum r probly loose as hell nd not even doing anything
