2. Head gasket - Wikipedia

   en.wikipedia.org/wiki/Head_gasket

   A leak in the head gasket - often called a "blown head gasket" - can result in a leak of coolant, the combustion gasses, or both. Blue smoke from the exhaust suggests that excess oil is entering the combustion chambers (although there are other possible causes than a head gasket leak). White smoke from the exhaust suggests that coolant is ...

3. Internal combustion engine cooling - Wikipedia

   en.wikipedia.org/wiki/Internal_combustion_engine...

   Only the fixed parts of the engine, such as the block and head, are cooled directly by the main coolant system. Moving parts such as the pistons, and to a lesser extent the crankshaft and connecting rods, must rely on the lubrication oil as a coolant, or to a very limited amount of conduction into the block and thence the main coolant. High ...

4. Core plug - Wikipedia

   en.wikipedia.org/wiki/Core_plug

   Core plugs can also sometimes prevent freeze damage to the motor. During the early stages of the freezing of the engine coolant a freeze plug will sometimes burst, and thus allow the coolant to exit the engine, before it might expand within the engine during the freezing process and potentially crack the engine block. [2]

5. Internal combustion engine - Wikipedia

   en.wikipedia.org/wiki/Internal_combustion_engine

   A head gasket prevents the gas from leaking between the cylinder head and the engine block. The opening and closing of the valves is controlled by one or several camshafts and springs—or in some engines—a desmodromic mechanism that uses no springs.

6. Radiator (engine cooling) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(engine_cooling)

   When the engine is cold, the thermostat is closed except for a small bypass flow so that the thermostat experiences changes to the coolant temperature as the engine warms up. Engine coolant is directed by the thermostat to the inlet of the circulating pump and is returned directly to the engine, bypassing the radiator.

7. Exhaust manifold - Wikipedia

   en.wikipedia.org/wiki/Exhaust_manifold

   When the engine is running, pistons are firing according to the engine firing order. If a bank has two consecutive piston firings it will create a high pressure area in the exhaust pipe, because two exhaust pulses are moving through it close in time. As the two pulses move in the exhaust pipe they should encounter either an X or H pipe.

9. Leak-down tester - Wikipedia

   en.wikipedia.org/wiki/Leak-down_tester

   Leak-down testing is a static test. Leak-down tests cylinder leakage paths. Leak-down primarily tests pistons and rings, seated valve sealing, and the head gasket. Leak-down will not show valve timing and movement problems, or piston movement related sealing problems. Any test should include both compression and leak-down.
