Leaking oil is very common. It is better to check your seals at least twice every year and replace those that are worn out. The leaks may sometimes be caused by scored or broken plungers or worn out packing.
Suppose you own a pressure washer and you want to begin a small car wash or auto detailing business, then firstly you have to keep in mind is that the pressure washer is working because after keeping it for some time, there is little preventive maintenance to be done so that the pressure washer is not damaged.
Secondly you should check the oil for pressure washers and see that the pump is filled to the appropriate levels. This can be done by looking through the eyeglass hole. Make sure that the inlet strainer is attached before you start the pump, so that no debris goes inside. Get all your industrial equipment from Ejawda.
Overflowing Of Oil
You should see that the oil does not overflow. There are two things which may cause the overflowing of the oil, the first is that it must have been overfilled, which is easy to do and can cause a problem. If the oil is foamy (a) then inside there is a blown seal, if it’s leaking from the seam (b) then outside there is a blown seal, if the oil is leaking out of the filler air hole (c) then it shows that too much oil has been put in.
If (a) and (b) then you require new parts, if (c) then not needed. Most of the kits are for the valves, those are fine unless they are melted or run out of water too long. It is said that CAT pumps have 9 lives, so maybe your pump is in good condition.
It is possible that there was a change in temperature in the garage overnight and the pump was overfilled with a lot of oil, so when the pressure changes inside the chamber the extra oil was forced through the little hole, used for air pressure breathing or if the pump begins to overheat. This is a safety valve scheme famous in Physics.
Why Does The Oil Leak?
The common reason is the rear and front crankshaft oil seals, as the time of running is very long and should be replaced. If after the maintenance, the tightening of the filter element is not done, it may leak oil, including diesel filter and machine filter.
Oil leakage may also be a poor seal of the Oil seal. The seals of the pressure washer are bound by the laws of Physics. They contract and expand based on how cold or hot the weather is. Weather with high humidity causes a pressure washer to begin leaking, especially when the water and oil are kept separate from each other.

Any one of the seal may break or get worn out at any time. This automatically causes a leak. It is not only that the oil leaks but it may also include water. Broken seals are generally due to lack of proper care of the pressure washer. The seals also expand and contract. This depends on the hot weather. Weather with high humidity causes the contraction and expansion of the seal and leads to leakage when the weather becomes hotter.
- Regularly Check The Seal – A proper and timely maintenance of the pressure washer pump is required to avoid the leakage of oil or complete damage of the pump. To prevent this, regularly check the seals, at least twice or thrice in a year and if required replace the worn-out seals. It is not possible to go for a DIY approach for maintaining the pressure washer but some manufactures make sure that the users are unable to do this. In such cases, it is better to call a regular mechanic.
- Use the correct seal to prevent leakage – If you wish that the pressure washer should last longer than ensure that the right seal is used properly. If you use a wrong seal for the pressure washer pump then it can lead to leakage which may lead to the breakage if not repaired timely.
Conclusion
You should properly read the buyer’s guide before installing the new seal to prevent any more damage to other parts of the pressure pump.
