2.0L/1.6L/1.4L Vauxhall Oil Pump Nylon Relief Valve Kit
2.0L/1.6L/1.4L Vauxhall Oil pump nylon relief valve kit including washers cures the problem of relief valve sticking, this is a highly recommended upgrade.
The nylon relief valve kit is recommended because particles from within the engine can jam the standard steel relief valve when they become wedged between the relief valve and the oil pump body. The nylon relief valve allows the particles to embed into the nylon relief valve, which means that the relief valve can still function without jamming.
We also recommend the replacement of the standard inner gear OS-SPG1
, the reason is that particles from within the engine pass through the oil pump pick up system, this cannot be prevented. The particles become compressed between the inner and outer pump gears causing the sintered standard gear to fail causing catastrophic engine failure. The new steel pump gear, which has a much higher strength is able to continue working way beyond the point that the standard gear would fail at, passing the particles through the oil pump and on into the oil filter.
Note: These components are only suitable for genuine GM pumps, all pattern versions are of poor quality and they will not fit.
We also stock an uprated oil pump assembly with all these components already fitted. Part no: OS-OP-VX2.0-HD-K01
