First off, thanks for the dumpvalve help if your reading this .
well down to the point, tonight i did the bypassing of the rear bcs and vac box, (amazing!) but whilst doing this i snapped a one way valve.
On the rocker cover to the left thereare two pipes coming off, i know the 1st one if the oil breather, but the second on has a one way valve and it looks like its going to the throttle body.
My question is, does this valve have to be a special one from vx, or can i buy, say a windscreen washerone way valve, will it do the same job?
