Probably a bad camshaft.
When the cam can be rotated several degrees without the lifter moving this indicates the lifter is on the base. This may not hold true with variable displacement engines or in the case or major valvetrain damage.
the forces acting on the weight lifter and the weights are balanced because the forces are not moving or changing direction.
This type of lifter, unlike its hydraulic counterpart, has no moving internal parts. This means it has no self-adjusting capability and therefore needs to have the rockers adjusted to give a certain amount of working clearance.
if the motor is running and the window is not moving the most likely answere is that the motor has disconected from the window reamove your door panal and reconnect the lifter arm between the two. the bolts get loose over the years due to vibration
the Olympic Weight lifter because the weights are much heavier then the microphone
Furniture sliders such as the EZ Furniture Lifter are devices that allow a person to lift the furniture slightly, place it on the lifter and slide it to the desired location. For some items that are frequently moved, casters or wheels can be attached to the bottom to make moving the item easy.
I don't think anyone can answer this for you without seeing and hearing the jeep. Listen to it while it's running and try to locate the noise. Be careful because the exhaust is hot and the fan will be moving while on
Compression/Exhaust.
A running monkey is a monkey that is moving very fast.
moving, running
At exhaust valve opening, pressurised gas reduces pressure by moving across the turbine blades and out of the exhaust pipe, the momentum of the moving gas is tapped by the turbine blades producing torque on the turbine shaft.
Only if you are moving it with your mind and not running the motor at all.
