Question about Cars & Trucks
A compression test is the only sure way. Remove the spark plugs. open the throttle or have some one depress the gas pedal to the floor, fit a compression gauge to number one cylinder , spin the motor over till the gauge no longer riser any higher, make a note of the pressure , repeat for the rest of the cylinders , now put 5ml of oil into number one cylinder and take and record the pressure .repeat for all cylinders . On the first test all cylinders should be within 10% of each other, If one cylinder is very low it may be a valve problem , if on the second test the low cylinder tests ok it is a ring problem. find the compression for the type of engine being worked on in the workshop manual. check against the recorded pressures if lower than 15% recondition for best results.

You know when the rings are gone because its hard to start /loss of oil on dipstick/ black smoke when starting up and running /fumes from under the bonnet and loss of power.
Also could be your converter blocked.
