Is it easy to repair oil leakage after the transmission is hit by a stone?
1 Answers
Whether the oil leakage after the transmission is hit by a stone is easy to repair depends on the extent of the collision. The following is an introduction to the situation of oil leakage after the transmission is hit by a stone: 1. Check for external oil leaks: Pay special attention to whether there is oil leakage at the front and rear crankshaft oil seals. Damage, aging, or wear at the contact surface between the crankshaft pulley and the oil seal can cause oil leakage at the front of the crankshaft. Damage to the rear crankshaft oil seal or a too-small oil return hole in the rear main bearing cap can cause oil leakage at the rear of the crankshaft. 2. Oil leakage at the front and rear oil seals: If oil seeps from multiple locations such as the front and rear cylinder head covers, front and rear valve lifter chambers, oil filter, and oil pan gasket, but no obvious leak is found, check the crankcase ventilation system. Clean the crankcase ventilation pipes and check if the PCV valve is malfunctioning due to carbon buildup and sticking. 3. Check the oil pressure: If oil continues to leak from the oil filter and some oil pipe joints after tightening, check whether the oil pressure is too high and whether the oil pressure relief valve is malfunctioning.
