Testing BOV

[jaymdee]

Hi,

 

I've previously posted that I've got a big wooshing sound from under the bonnet at WOT and that it may be my stock BOV. I've got 2 BOVs, and I get the same sound with each of them fitted. Last night I applied 1Bar pressure to the small pipe and 1.5Bar to the inlet pipe to the BOV and it held fine, no leakage.

 

Is this how the BOV would see pressure in real world driving?

 

If so, I've eliminated that from leaking. Now I need to find what else could be causing it. Could it be the pipes on the EGBV at the back of the engine bay? I'm finding it difficult to understand what pipes are pressurised when in the stock seq system.

 

cheers
