Die \u201eKopfdichtung\u201c, wie Sie unter Kfz-Mechanikern oft genannt wird, ist starken thermischen und mechanischen Kr\u00e4ften ausgesetzt. Da sie dem Kompressionsdruck aus den Brennr\u00e4umen des Motors dauerhaft standhalten muss, ist sie einer permanenten Belastung ausgesetzt. Die von den Motorenherstellern angegebene Lebensdauer einer Zylinderkopfdichtung betr\u00e4gt bei normaler Fahrweise im Schnitt 150.000 Kilometer.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Is the Head Gasket<\/a> damaged, there is a risk of high costs. The conventional method of repairing a defective cylinder-head gasket is to replace it. This is usually a time-consuming process, as in some vehicles the engine has to be removed, dismantled into its individual parts and then reassembled. Depending on the vehicle, model and year of manufacture, this takes an average of 8-10 working hours in an automotive workshop specializing in engine repairs.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The cost of replacing a defective cylinder-head gasket is often out of all economic proportion to the residual value of the vehicle. Moreover, the installation and removal of a defective cylinder-head gasket is often not without risk. This is because combustion engines, especially cylinder heads, \"warp\" over time and with increasing mileage. This is due to the high thermal and mechanical stresses to which a combustion engine is exposed over the years. Replacing the cylinder head gasket alone is therefore often not enough. The cylinder head must be ground flat so that it is fully seated on the new cylinder-head gasket. As many workshops often do not have the facilities to properly surface grind a cylinder head, this step is outsourced to external specialists (engine reconditioners). Additional costs are incurred and the repair bill quickly exceeds the thousand euro mark.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Yes, provided that the problem is on the cooling water side and is detected in good time (preferably as soon as the first signs of the problem appear). Symptoms of a defective cylinder head gasket<\/a>) and tackled. Because as long as the engine still starts and runs for 60 minutes when stationary, a chemical repair is possible. And at a fraction of the effort and cost compared to a mechanical repair. In recent years, chemical repair by means of coolant-side filling solutions has proven its worth and has gained acceptance in specialist circles. These work on a thermal basis and use \"bonding\" (thermal hardening) to create a permanent seal on the coolant-side leaks of a combustion engine, including leaking cylinder head gaskets or hairline cracks on the cylinder head or engine block.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t
