How to Assess the Engine Cylinder Head and Bores Including Valve Stem Oil Seal Replacement

In our first class, Danny and Clive dig into the engine bay to inspect a number of components prior to starting the engine. Cold engine checks are recommended for taking a closer look at hoses and other smaller parts of the engine that easily show damage and wear by shining a light. Before moving on to the next class, make sure you’ve inspected each of the components seen in this video.

In the second half of our cold engine check, Danny and Clive disengage the spark plug leads to take a closer look at the quality and cleanliness of the spark plugs. They also inspect the brake and clutch fluid reservoirs, oil and coolant. Before cracking on to the warm engine inspection, be sure to walk through each of the components Danny and Clive cover, looking for damage and other abnormalities.
