Selespeed Check Valve

[electrostar 0]

As with most people i have had a few issues with the selespeed system on my 147 2.0TS. None of the diagnosis has ever pointed to the check valve which sits on the high pressure side. Could it be possible for the check valve to fail or not seat correctly which allows the system to depressurise back through the pump to the reservoir.

 

I have just replaced my accumulator and have to admit that the pressure built quicker than it had done before which suggests that the fault was with the accumulator but while i still have everything in bits i was hoping to put this one to bed for a few thousand miles. Going to do the motor brushes while i have the opportunity also.

 

Any Thoughts

The cnances of the check valve (before the accumulator in the system not seating correctly are so slim that it's 99.999999% never going to cause a fault, the filter before it will catch anything big enough to cause it to stick open.

Thanks Smaky I had wondered why there was never any mention of it as being a cause. Just need to replace the brushes on pump motor now and i should be good to go.

Hope you find the guide useful, but there is another style of motor out there which uses a different body to the one in the guide.

I've got the Magnetti Marelli Selespeed motor, the brushes differ a bit in size, it's pretty much square at 8x8x25mm if I remember correctly.
