Cylinder Head and engine block crack Detection

also pressure testing

With today’s high labour costs, you can’t afford to waste a lot of time machining and reconditioning cores and used parts that may be flawed. Though some cracks may not be a concern (depending on their location), others can cause serious problems. Even if a crack is not very big or leaking now, there’s no guarantee it will stay that way. As a rule, cracks usually spread and only get worse as the miles accumulate. Heat, thermal stress, heavy loads, repeated bending and flexing, metal fatigue, pounding and vibration are all factors that contribute to the formation of cracks and make them grow. So if metal is pulling away from metal, it means an area is experiencing more stress than it can handle. That's why cracks form in the first place.

If critical parts are not inspected for cracks, there is no way to know if they will stand up to normal use. In the case of cylinder heads and blocks, you will not know if the castings can hold pressure until the engine has been assembled and run up to working temperature, even then you could discover that the whole thing is no good. This is why crack detection and pressure testing at the overhaul stage is essential.
