Pipeline leaks will generate a lot of dangerous problems, so it is important to fix the leak off pipe connectors in time. So how to repair leak off pipe connectors?
Check the problem
Fix leaks off pipe connectors
First check whether there is an oil leak on the outside. Pay special attention to whether the oil seals at the front and rear ends of the crankshaft are leaking. Cracking, aging, or wear of the contact surface between the crankshaft pulley and the oil seal on the front end of the crankshaft may cause oil leakage at the front end of the crankshaft. The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cap is too small, and the oil return is blocked, which may 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 is leaking. The oil seal should be replaced in time if the oil seal is aging or broken.
If oil leaks at the front and rear oil seals. Even the front and rear cylinder head covers, front and rear valve lifter chambers, oil filters, oil pan gaskets and many other places where organic oil seeps, but no obvious oil leaks can be found, check the crankcase ventilation device and clean the crankshaft The ventilation ducts of the tank, especially to check whether the PCV valve does not work badly due to carbon deposits and glue sticking. If the crankcase is poorly ventilated, the pressure in the crankcase will increase, which will result in multiple oil leakage.
If the oil filter and some oil pipeline connectors are still leaking after being tightened, check whether the oil pressure is too high and the oil pressure limiting valve is not working properly.
Use plugging glue for plugging
This kind of plugging method can be used for metal pipes and non-metal pipes, but the effect of metal pipes is obviously better than that of non-metal pipes. Nowadays, there are endless layers of plugging glues on the market, but the principle is similar, and they are all coated and sealed by modulating glue.
This repair method is suitable for metal pipes and non-metal pipes. The weld protrusion is within 5mm. If it exceeds, the repair cannot be completed. The pipe repairer is mainly sealed by the inner sealing rubber gasket. Since the inner rubber gasket is designed with strong lips and teeth, not a flat rubber plate, it can repair slightly raised pipes with welded seams. This tool is relatively simple to operate and everyone can use it.
Repair welding is the most traditional repair method. This method can only be used for metal pipes and has the longest existence. After this method is repaired, the possibility of secondary leakage of the pipeline weld is relatively small, but because it is a professional technique, it requires more professional operators.
Although there are many ways to repair, the easiest ones are tapes and patchers. If you still haven't repaired leak off pipe connectors, just find a professional master.
