Try these questions from our free Automotive Engine Rebuilders Association Certification practice tests. The correct answer and an explanation follow each question.
When performing a wet compression test and results improve significantly compared to a dry test, this indicates:
- A. A leaking head gasket
- B. Worn or damaged piston rings
- C. A stuck-open exhaust valve
- D. Excessive valve stem clearance
Answer: B. Worn or damaged piston rings
Oil added to the cylinder temporarily seals worn rings; a big improvement from dry to wet test confirms ring and/or bore wear as the source of low compression.
