Is it easy to repair a transmission that is leaking oil after being hit by a stone?
1 Answers
Whether a transmission is easy to repair after being hit by a stone and leaking oil depends on the extent of the collision. Here is an introduction to the situation of a transmission leaking oil after being 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. A broken, damaged, or aged front crankshaft oil seal, or wear on the contact surface between the crankshaft pulley and the oil seal, can cause oil leakage at the front of the crankshaft. A broken or damaged rear crankshaft oil seal or an excessively small oil return hole in the rear main bearing cap that obstructs oil return can cause oil leakage at the rear of the crankshaft. 2. Oil leakage at the front and rear oil seals: If there is oil seepage in multiple areas such as the front and rear valve covers, front and rear valve lifter chambers, oil filter, and oil pan gasket, but no obvious oil leak can be 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. Oil pressure: If the oil filter and some oil pipe connections still leak after tightening, check whether the oil pressure is too high and whether the oil pressure relief valve is malfunctioning.
