If you’re like most people, you probably don’t think about your car’s engine very often. But when you do, you might notice something strange: a big scratch on the aluminum cylinder head. While this may not be a big deal to some, others might be wondering how to repair it. Luckily, it’s not as difficult as you might think.
First, you’ll need to remove the cylinder head from the engine. This can be done by disconnecting the head from the engine block. Next, you’ll need to sand down the area around the scratch. Once you’ve done that, you’ll need to apply a sealant to the area. Finally, you’ll need to reattach the cylinder head to the engine block.
