In the previous class, Ed showed you how to clean the valves and prepare them for reinsertion into the head. Now, you’ll learn how to lap in the valves using grinding paste and then decoke the engine in order to increase its efficiency and ensure top-notch engine performance for another several thousand miles. Ed introduces the tools you need to complete this process and then shows you how to use them.
In the final step of the engine decoking process, you’ll learn to reassemble the head, replace a new gasket, and remount the cleaned and decoked components onto the engine block. Ed walks you step by step through the finishing methods needed to put the cylinder head back together and make sure everything is properly affixed and operational.
There are multiple reasons why you’d need to remove the cylinder head from the engine of your classic car. Ed Hughes teaches you what to look for when deciding whether to remove the head, and then demonstrates the proper technique for doing so.
