Technician A uses a steel gasket scraper on aluminum engine parts. Technician B uses a plastic or wood scraper on aluminum engine parts. Which technician is correct?

• A. Both technicians are correct
• B. Only Technician A
• C. Only Technician B
• D. Neither technician is correct

Answer: (C)

Using a plastic or wood scraper on aluminum engine parts is the appropriate method to avoid damage to the softer material. Aluminum is more prone to scratching or gouging when it comes into contact with hard metal tools, such as steel. A steel scraper can easily create abrasions or uneven surfaces on aluminum components, potentially leading to sealing failures or compromising the integrity of the parts. In contrast, plastic and wood scrapers are designed to be softer and less abrasive, allowing for effective cleaning without risking damage to the aluminum surface. This method preserves the condition of the parts, ensuring that they will maintain their functionality and seal properly once reassembled. Therefore, using a plastic or wood scraper is the correct approach when working with aluminum engine parts.
