Question

a technician could perform a wet compression test to narrow down the cause of low compression. technician a says that if the compression stays the same, there could be worn piston rings. technician b says that if the compression rises, the issue is with the valves. who is correct? select one: a. technician a b. technician b c. both a and b d. neither a nor b

Explanation:

In a wet compression test, if the compression stays the same, it indicates a problem with the valves (not piston rings as Technician A claims). If the compression rises, it indicates a problem with the piston rings (not valves as Technician B claims).

Answer:

d. Neither A nor B
