Information - Cylinder head screws
The performance accuracy of all elements of the engine is very important and this became an axiom. And the tightening of the cylinder head bolts is not an exception. And the reason is simple. Imagine the load experienced by all elements of the mount: strong temperature fluctuations, and constant vibration. As a result of numerous studies inquired by professionals, the weight consists of 5000 kg or more. Imagine what kind of pressure undergoes every engine bolt while accelerating. To ensure the connection between the block and the cylinder head, you have to make sure that the bolts are stable long enough.
In most cases, the bolt is oblongated. Screwing this item in a block that has been affected by corrosion, torque is increased by several tens of units before the parts were linked up. If you have already tightened the bolt, you must know that the tension increasing is gradual and the material will initially take it`s elastic state, until, finally, will become ductile.
Later a further tension will lead to irreversible deformation of the material. In this state, the torque does not increase with any further tension. In practice, this condition is almost impossible to observe, if only the bolts are not lubricated with grease or oil in order to reduce the frictions to zero. Do not forget that the surface of the block and cylinder heads must be very well processed, they should not be wavy.
Particularly important are the transitions from one item to another. Remember that all replacement parts must be certified, like those offered in our online store. And apart from cylinder head bolts, you can also purchase expansion flanks, valve injectors and other parts and components.
Cylinder head bolts: lifetime limits, common defects and their signs, tips and recommendations
The cylinder head bolts have no specified lifetime limit. Their replacement is performed at every demounting of the cylinder head, because of construction peculiarities (stretching properties) repeated installation of these parts may lead to their destruction.
Presence of engine defects may be pointed out by failures in its operation. They can be removed only by demounting of the cylinder head for diagnostics or repair. If there is a trip-computer in the car, it will indicate failure corresponding to engine defect. Also, dense white smoke from the exhaust pipe can be visible, and it indicates engine overheating.
Diagnostics of the cylinder head bolts is performed by specialists at a service station: they define, if there is necessity to demount the cylinder head and as a consequence – replace the bolts. Procedure of cylinder head demounting requires special skills and usage of peculiar equipment, for example, a lifting device, a torque wrench, etc.
As a rule, the cylinder head bolts are replaced at a service station. They are screwed with the help of a torque wrench in a strictly specified sequence with a precise tightening torque. Improperly tightened cylinder head bolts may lead to breakdown of the component and its elements.
