-The IPR Valve is responsible for controlling the pressure in the high-pressure oil system which in turn operates the fuel injectors. The IPR (injection pressure regulator) is located on the back of the high pressure oil pump. Because of the high pressures they are responsible for controlling, the IPR valve o-rings are a semi-common failure which will, in turn, result in such low oil pressure related symptoms as poor idle, stalling, and even a no-start condition. While there are other potential causes, such as a failed IPR valve, the o-rings themselves are often at fault, and are much less expensive to replace.
This kit includes three o-rings / seals and a retaining nut.
