Tuning the vehicle usually involves a considerable exchange of vehicle parts. Especially in the area of performance tuning, the car parts of the car have to be adapted to the new performance. What good is a big one Turbo, Chiptuning or a new one Air Intake System if the cylinder head gasket is crap. The cylinder head gasket is a particularly important part of the vehicle that is significantly involved in the power distribution and transmission of the vehicle and must be adjusted accordingly when tuning. The cylinder head gasket and improved variants are discussed in more detail below.
improved cylinder head gasket
The cylinder head gasket is a component in the car that is between cylinder head and crankcase. The cylinder head gasket is often simply referred to as the head gasket and is used to seal engine oil ducts, cooling water ducts and the combustion chamber. In addition to the sealing, the head gasket also takes over the power transmission between car components. The force distribution is an important influencing factor and it should work at least as well as before, especially after tuning. An improved cylinder head gasket may therefore be necessary during tuning.
What to pay attention to?
Tuning the vehicle may require an improved head gasket. It should be noted that there are head gaskets of different thicknesses and the number of holes must be observed. (e.g. 3-hole: 1,71 mm, 2-hole, 1,63 mm and 1-hole 1,55 mm). A standard gasket may no longer be sufficient for a machined cylinder head / engine. In various forums, tips on machining the cylinder head are given and work afterwards so that the head gasket fits. In general, such grinding and tuning work should be carried out by experts. It is advisable to purchase a cylinder head gasket specially adapted to the new conditions after working on the engine block or the cylinder head. Specialist dealers offer reinforced cylinder head gaskets that are suitable, for example, for motorsport and road use.
Cylinder head gaskets - buy from specialist dealers
If you are looking for high-quality cylinder head gaskets, you will find them at specialist dealers. There are many offers on the Internet. However, it is difficult to make a statement about the quality of the goods. It is important that you order from well-known companies that offer articles for the tuning area and racing and know your way around. Customer reviews and tuning forums can help you choose the right cylinder head gasket. In addition, the interested customer can tune the car completely in experienced tuning workshops and have the cylinder head gasket replaced with an improved variant. If a workshop has made the changes to the engine, it can also best estimate which cylinder head gasket is required.
Reinforced cylinder head gaskets - advantages?
Improved or reinforced head gaskets have, for example, a compression reduction. The articles have a multi-layer structure and are made of metal. The material of these cylinder head gaskets is also known as multi-layer steel. The cylinder head gaskets have coated, thicker intermediate plates and in this way increase the compression. Corresponding head gaskets with specially made intermediate plates are available commercially. When buying, you should pay attention to suitable head gaskets for the respective vehicle types.
Summary information on the cylinder head gasket / cylinder head - symptoms, repair / replacement and the costs:
- the cylinder head sits on the engine block and closes it off at the top
- The cylinder head gasket sits between the cylinder head and the engine block and seals the two components against one another
- the cylinder head contains, among other things, the valve control, various inlet and outlet channels, the injection nozzles or injectors and, if available, the spark plugs
- Damage to the cylinder head or the cylinder head gasket can lead to restrictions in the cooling or lubrication of the engine (can lead to engine damage)
- Symptoms / signs - Defect on the cylinder head or or defective cylinder head gasket
- white / blue smoke from the exhaust
- massive oil loss over a short period of time
- heavy loss of cooling water
- Exhaust gases in the cooling system
- Fault memory entry such as "misfire cylinder X"
- Engine oil in the cooling water circuit
- Cooling water in the oil circuit
- Oil leak on the cylinder head (mostly with cooling water) - Continue with damage to the cylinder head / defective cylinder head gasket?
- you have to go to a workshop as soon as possible
- the risk of engine damage is high
- the engine oil and cooling water can mix
- There is a risk that the motor will no longer be cooled correctly due to the loss of cooling water - Defect on the cylinder head - confusion with what possible?
- with damage to the engine block / crankcase - Damage to the cylinder head / cylinder head gasket and general inspection
- depending on the exact symptoms
- There is no sticker in the event of an oil leak with dripping
- Slight oil sweating is not a problem
- A loss of cooling water or a failed exhaust emission test results in the failure of the general inspection - Repair / replacement of cylinder head or cylinder head gasket
- It may be necessary to replace the entire cylinder head or just the cylinder head gasket (depending on the individual case and the symptoms)
- Concrete analysis only possible by dismantling the cylinder head
- It is often enough to replace the cylinder head gasket with a new part - Course of work
- Dismantling of the cylinder head and other components such as spark plugs, injection nozzles, intake manifold and / or manifold (drain cooling water)
- Loosen the toothed belt or timing chain from the camshaft wheel
- dismantle the cylinder head
- analyze the leak
- Replace the cylinder head gasket / the damaged component
- Replace any additional components (depending on the damage, this can be the valves / valve stem seals, piston rings, pistons, engine block)
- Cylinder head screws are expansion screws, they always have to be replaced - Cost of repairs to the cylinder head
- The prices differ depending on the cause of the leak and the effort involved in dismantling the cylinder head, depending on the vehicle model and engine
- only changing the cylinder head gasket causes material costs (e.g. parts from Elring) of approx. 100 to 500 euros
- Depending on the type, the entire cylinder head costs between 500 and 2.000 euros
- Alternatively, there are completely overhauled cylinder heads
- The time required depends on the dismantling of other components and the cause of the leak as well as the duration of troubleshooting
- Working time of three to eight hours is common (300 to 800 euros.)
- plus costs for engine oil, oil filter
- Depending on the engine, new cooling water costs around three to five liters for between 20 and 60 euros
- Depending on the design of the engine, two cylinder banks with two cylinder heads and thus two cylinder head gaskets can also be installed
We hope that you the info report on the topic / term Cylinder head gasket (Further designations / keywords: head gasket, engine gasket, engine gasket) from the field of autotuning.
