How to replace throttle oil seal in Skoda

It is normal that the oil seal is broken and the car can't work, so it must be replaced immediately.

① First check whether there is oil leakage outside. Pay special attention to whether the oil seals at the front and rear ends of the crankshaft leak oil. Damage or aging of the oil seal at the front end of the crankshaft or wear of the contact surface between the crankshaft pulley and the oil seal will cause oil leakage at the front end of the crankshaft. The oil seal at the rear end of the crankshaft is broken or damaged, or the oil return hole of the rear main bearing cover is too small, and the oil return is blocked, which will cause oil leakage at the rear end of the crankshaft. In addition, pay attention to whether the oil seal at the rear end of the camshaft leaks oil. Oil seal aging, cracking and oil leakage should be replaced in time. In addition, it is necessary to check whether there is external leakage in all parts of the engine lubrication system. ② If the front and rear oil seals leak oil, even the oil seeps from the front and rear cylinder head covers, the front and rear valve tappet chambers, the oil filter and the oil pan gasket. However, no obvious oil leakage was found. Check the crankcase ventilation device and clean the crankcase ventilation pipeline, especially check whether the PCV valve is not working well due to carbon deposition and viscose. If the crankcase is poorly ventilated, it is likely to lead to an increase in the pressure in the crankcase, leading to multiple oil leaks. (3) If the joint between the oil filter and some oil pipes still leaks oil after fastening, pay attention to check whether the oil pressure is too high and whether the oil pressure limiting valve works abnormally.

There are three direct consequences of oil seal damage: 1, the oil enters the cylinder along the valve guide rod, which leads to the accelerated carbon deposition and oil pollution of the spark plug, the working condition deteriorates or even does not work, and the engine power is reduced; 2, the valve tilt cylinder is not tightly sealed, the cylinder pressure drops, and the engine power is weakened; 3. Accelerating fuel consumption When the car is driving for a long distance, it is easy to cause the engine to be damaged due to lack of oil. In addition, after the engine oil enters the cylinder to participate in combustion, some carbon is deposited in the engine oil, which makes the engine lubrication condition worse and aggravates the engine wear.
