As per thread title really ..

Took the valve out as i replaced the hoses but did\'nt look which way the arrow was pointing..anyone know ?

I imagine you want the arrow to point towards the map sensor, as you want it to sense boost. But i\'ll just check for you...

[nikp]

mine didn\'t have an arrow on...not that i could see anyway! grr

surely map sensor should have a 2 way filter only! As by the nature of what it does it needs to read both manifold vacuum and boost to operate correctly.

I think its a filter not a valve

Explains why there was no arrow on mine then!

It\'s a filter not a valve.... but the arrow should point towards the MAP sensor..
