For a while now I have had a bad rattle on my 96. Its got about 103,000 miles on it and still strong. My problem is that when the truck gets warmed up the motor starts to develope a bad rattle. It only has it at low RPM and while sitting at idle in drive. The rattle tends to die down when in park though. I lifted the hood and tried to listen around for anything. I couldnt pin point the problem but it seems to be comming from the back rockers, or under the vlave cover to say the least. Has anyone had this problwm w/ their 2.2? Should I re-torque my rocker bolts? Any info would be greatful. I hate having a nice truck w/ a shitty sounding motor.
