Any capable restorer of classic cars ought to know how to decoke an engine. Over time the engine on a classic car becomes backed up with carbon, which causes the efficiency of said engine to drop. When enough carbon builds up, it might be time to decoke the engine–but how do you know whether it’s the right time?
Throughout this course, Danny and Ed will teach you some of the basic tips any car restorer needs to correctly maintain cylinder heads and gaskets, focusing on how to decoke an engine once the head has been removed.
In the first step of our five-part course, Ed Hughes teaches you the basics of electricity and how these basics apply to the wiring on your classic car. You’ll learn some of the key terms that will come in handy later in this series, including the essential technology that connects your car’s electrical components to the car’s battery.
Once you’ve removed the cylinder head from the engine block, it’s necessary to dismantle the head to properly assess its condition and decide the next course of action. Ed teaches you how to search for any damage on the surface, including to the valves, head and copper sealing rings and the head gaskets, and then takes the head apart to have a look at each of the components inside.
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.
