Fault Diagnosis and Removal of Engine Cylinder Gasket Ablation 3
---------- Causes of cylinder head ablation failure
①The tightening force of the cylinder head bolts is uneven, or the tightening force is not enough.
②The joint surface of the cylinder block and the cylinder head is deformed.
③ The engine often runs under the conditions of heavy load, premature ignition, engine overheating, and knocking.
④The quality of the cylinder head gasket itself.
Cylinder head ablation failure phenomenon
①The engine is not running smoothly, and there is a "sudden" sound in the exhaust pipe.
②The working performance of the engine deteriorates, the power drops, and the speed cannot be increased.
③Blow-by gas from two adjacent cylinders, low cylinder pressure, sometimes the intake pipe is tempered, and the exhaust pipe is fired.
④ Blow-by gas at the water channel of the cylinder head gasket, resulting in air bubbles in the engine radiator.
⑤ The coolant leaks into the cylinder, white smoke is emitted, and the engine is difficult to start.
⑥ The coolant leaks into the crankcase, causing the lubricating oil level to rise and deteriorate.
⑦ The temperature of the engine is high, and sometimes there is water leakage at the edge of the cylinder gasket outside the engine.
Cylinder head ablation failure phenomenon
() Burning loss between the two cylinder edges of the cylinder head gasket:
The engine power is insufficient, the car is weak, and the acceleration is poor. When the air filter is removed, when the engine is idling, the intake pipe port can hear "pop"
(2) The burnt part of the cylinder head gasket is connected with the water jacket hole:
There are bubbles in the water tank, boiling of the pot, and white smoke from the exhaust.
() The burnt part of the cylinder head gasket is connected with the oil passage:
Part of the oil will be ablated into the cylinder, and the exhaust will emit blue smoke.
() The burnt part of the cylinder head gasket is connected to the external atmospheric environment: the engine has poor power performance, the economy deteriorates, and there is a violent choking from the damaged part of the head gasket.
Silence.
