Question

1. a driver complains that her oil pressure light flickers on and off at stoplights. technician a says the oil level in the engine should be checked. technician b says that the indicator light circuit could also be at fault. who is correct?
2. each of the following problems may be found in a lubrication system except:

a. low oil pressure
b. high oil pressure
c. low oil consumption
d. high oil consumption

1. external oil leakage may be detected by:

a. high oil consumption
b. oil puddles under vehicle
c. oil - wet areas around engine
d. any of the above

1. oil dye is sometimes added to motor oil to detect leaks. t or f?
2. which of the following is not a common cause of low oil pressure?

a. worn oil pump
b. thin or diluted oil
c. leaking valve stem seal
d. clogged pick - up oil screen

Explanation:

Question 10

For the oil pressure light issue: Checking oil level (Tech A) is valid as low oil can cause pressure issues. The indicator light circuit (Tech B) can also fail, causing false signals. So both could be correct, but if choosing, both A and B have valid points. But likely the answer is both, but if options (not shown) assume, but based on context, both technicians can be correct as oil level and circuit issues can cause the light to flicker.

Lubrication system problems: Low oil pressure (a), High oil pressure (b), High oil consumption (d) are issues. Low oil consumption (c) is not a problem of the lubrication system (it's a positive or not an issue here). So the exception is low oil consumption.

External oil leakage: High oil consumption (a) can indicate leakage (as oil is lost), oil puddles (b) are direct leakage, oil - wet areas (c) are direct signs. So any of the above (d) is correct as all can detect external leakage.

Answer:

(Assuming options where both are correct, e.g., A and B are correct. If options were A, B, both, then "both Technician A and Technician B are correct")
