High oil pressure in an Isuzu KB 250 can be caused by several factors, including a malfunctioning oil pressure relief valve, a clogged oil filter, or a viscosity of oil that is too thick for the operating conditions. Additionally, issues like excessive engine wear or oil pump malfunction can contribute to increased pressure. It's important to diagnose the specific cause to prevent potential engine damage. Regular maintenance and using the correct oil type can help mitigate these issues.
They are actuated by hydraulic pressure. An electric solenoid closes a passage that allows high pressure oil to flow through an inlet check valve and back to the sump. When that passage is closed the oil pressure acts on a plunger in the injector and strokes it. When the solenoid is released the oil is vented through the outlet and back to the sump.
The sump is the oil reservoir. An oil pump lifts the oil from the sump and forces it under pressure through the engine. The oil then returns to the sump to be used again. Some sumps have fins on then - this acts as a cooler to help cool the oil in the sump.
High velocity sump pump can be rented from Sam Wexler Plumbing. It is also available at King Sanitary Service.
pressure in the sump caused by engine breather pipe being restricted or blocked is one cause for oil coming up through the dipstick hole
The purpose of a sump pump vent is to release air pressure from the sump pump system, allowing water to flow freely and preventing airlocks. This helps the sump pump operate efficiently by ensuring proper drainage and preventing clogs or malfunctions.
1- Pressure switch located on top to "read" the hydrostaric pressure above the pump housing=2- A float preset to a desired height to keep the water level from over flowing the sump pit=
If you mean that diesel is somehow getting into the oil sump and the oil level is rising then this is quite common with this engine and is due to either the injectors or the injector seals failing. Loads is on Google about this problem. This car was recalled by Isuzu to have it fixed. If a car wasnt recalled then its a time bomb and if injectors need replacing it costs a fortune.
no because a booster pump is made for higher pressure and a sump pump is made for volume so you can never have the same pressure as a booster pump.
A broken sump, possibly due to a broken Con-Rod.
faulty liners/porous block or cracked head/head gasket
Pumps clog due to excessive debris volume, debris size, or debris shape. Pumps are rated for handling debris at a given size, but usually it's considered a 'spherical' diameter for passage. Low pump discharge velocity or heavy debris weight can also add to a pumps clogging due to the inability for a pump to move the solids away from the sump. 'Ragging' of a pump is a type of clogging that occurs between the impeller and volute by material trying to pass from the high-pressure side to the low-pressure suction side, getting stuck, and stopping the impeller from turning.
Essentially a sump pump encased in a concrete volute to reduce noise and vibration. These are desirable for high volume, continuous use applications.
