Q:What are the problems caused by engine oil pump damage?

The damage to the diesel engine oil pump will cause the following problems and solutions:(1) the oil inlet and outlet pipe of the oil pump is leaking at the joint, the oil pump stops supplying oil, and the inlet and outlet pipe gaskets are replaced, and the sealing surface is tightly sealed.(2) oil pump, check valve and seat surface wear or damage, failure, the oil pump does not supply oil, grinding, check valve seat surface or replace the check valve.(3) the oil pump piston wear and seal failure, the oil pump to stop oil supply, replace the piston treatment.(4) the oil pump piston spring is broken, the oil pump fails, the piston pump oil function is stopped, the oil pump is not supplied, the piston is replaced and the piston is taken off.(5) the oil seal of the piston rod of the oil pump is damaged, which causes the diesel oil to enter the injection pump cam chamber, and makes the engine oil of the diesel engine bottom oil become thinner. At this point, the oil seal of the top rod should be replaced.

Q:Bending machine, oil pump motor abnormal sound, what's the matter?

First, the hydraulic oil is not enough, will cause abnormal sound of the pump, check the amount of oil enough;Two, hydraulic oil dirty plug, oil suction port filter will cause abnormal sound, and oil cylinder, motor and other components of the work is not easy, in this case, wash the filter, and filter hydraulic oil or replace hydraulic oil;Three, the pump is damaged, the inner surface of the stator vane pump will wear a different sound, internal plunger piston pump will damage the abnormal noises and vibration of hydraulic system badly, the stress of this situation would not be stable, may be due to a hard object inside the hydraulic oil in the pump caused by card;Basically, these three situations.

Q:How long will the oil pump lubricate the engine parts after the engine is started?

According to my driving experience, it is better to warm up in 5-10 minutes after the cold weather, and start in hot weather for 1-2 minutes

Q:TOYOTA Camry oil pump how to change?

To fall apart, engine, gearbox, valve cover, timing cover, timing chain, gear, oil pan, then you can disassemble the pump replacement.

Q:Today I heard the cabin with "abnormalsound kakaka", open the hood, it sure is not the sound of the engine, the engine abnormal sound from below, the noise is very clear, like gear sounds like a roller coaster, just started the sound when uphill, and the throttle is louder. Said the faster speed is louder. Open repair factory, the mechanic said the oil is not a talk ambiguously to oil, oil change, I don't believe him, home to search the Internet, there are two possible judgment: one is the abnormal sound of valve rod hit what caused by catheter, pump two is bad, not to pump oil.I do not understand the car, I hope to have a professional friend to help me judge, in the end what is the reason, in the end is not serious? The car is new Elysee 16V. Is it the beginning of winter without preheating? StopI went to another repair shop today and said the valve was broken. I don't know. Isn't it serious?

It's mostly the sound of the valve

Q:What's the reason that I changed the new oil pump instead of the engine oil?

Did you try the oil pump before loading?

Q:The car burning oil pump replacement must do

1, there are many reasons, but also models (steam, firewood) and so on.2, long-term use of poor quality oil, or viscosity grade unqualified engine oil and other internal wear too large.3, under normal circumstances, the engine will burn some of the oil from the cylinder block, piston and valve lubrication, consumption within the relevant provisions of the national standard range for normal (GB/T19055), and vice versa. The lowest scale car burning oil is often accompanied by smoke or in a maintenance period is lower than the oil gauge oil level.4, long time does not change oil or too long delay, not timely maintenance; piston and piston ring due to the use of long, normal wear, or abnormal wear and tear caused by the gap is too large.5, in addition, there are valve seals, crankcase forced ventilation, PCV valve damage, congestion, oil pump pressure, or its own failure can also be caused.There are many reasons why, as you describe the content is not detailed, the temporary analysis so far.

Q:07 years of A4 1.8T. Cold start is not sound, after a few minutes to normal temperature will appear abnormal sound, especially when on the road uphill. The throttle speed will be a strong metal came "crashed" knocking at 1800 to 2200 (window to hear), very annoying. Go to the garage to the handbrake tension half clutch throttle to 2000 rpm, the master said to be in the engine sound, estimated to be reason for oil pump, please master can analyze is not the case. Thanks a million.

The oil shortage caused by the oil pump jam is insufficient

Q:Automobile engine oil pump does not leak pressure, which causes oil seal ring to leak seriously. What is the trouble?

1, check whether there is lack of oil.2, the condition is not very old, check the oil pressure sensor.3, sensor no problem, check the oil pump, see if the pump is not enough oil.Automobile engine oil pump with crank, when the engine speed of pump oil is high, therefore need a pressure relief valve to keep the oil pressure of the main oil channel, the excess oil drain back to the oil pan, if the oil pump pressure relief valve failure, no pressure relief will lead to the oil pressure is too high, will be oil lattice sealing collopse. If the pressure relief valve normally open, it will cause oil pressure is too low, will burn bearings and the like.
