What should you do during cylinder head fins inspection to prevent debris from entering the cylinder head?

• A. Scrape off build up and clean with degreaser
• B. Keep Spark Plug in to prevent debris from entering cylinder head
• C. Remove cylinder head
• D. Spray with water

Answer: (A)

During cylinder head fins inspection, the goal is to remove any oil, resin, or dirt stuck in the fins so debris won’t fall into the cylinder head when you inspect or reassemble. Scraping off buildup and cleaning with a degreaser does this effectively: the scraper loosens and lifts grime, and the degreaser dissolves oil and grime, making it easy to wipe away. This keeps the fins clean and helps you spot any damage while preventing debris from entering the cylinder head. The other options aren’t appropriate: leaving the spark plug in place won’t stop debris from entering around the plug area; removing the cylinder head is unnecessary for fins inspection; spraying with water can spread debris or cause moisture issues.
