Vertical rammer leakage repair
If crankcase ventilation is poor, it is likely to cause pressure in the crankcase to rise, resulting in multiple oil seepage.If the oil filter and some of the oil pipe joints after tightening or oil leakage, should pay attention to check whether the oil pressure is too high, the oil pressure limiting valve is not working well.
In addition, we should also pay attention to whether the camshaft rear oil seal is leaking. Oil seal aging, rupture, oil leakage should be replaced in a timely manner. In addition, check the engine lubrication system for leakage of parts.If the oil leakage at front and rear oil sealEven after the cylinder head cover, and the valve tappet chamber, oil filter, oil sump liner multiple oil exudation, but can not find obvious leakage, should check the crankcase ventilation, clean crankcase ventilation pipe, especially to check whether the PCV valve due to carbon deposition and glue card lag caused by bad work.
First, check if there is an oil leak outside.Pay particular attention to whether the oil seal at the front and back of the crankshaft leaks. The front end of the crankshaft is broken, damaged, worn or worn by the crankshaft pulley and the oil seal, causing the front end of the crankshaft to leak oil. The oil seal at the rear of the crankshaft is broken or damaged, and the oil return hole of the rear main bearing cap is too small, and the oil return is blocked, causing the rear end of the crankshaft to leak oil.
