Tial bov

[hbkuk1]

Fitted this today and now the car won't idle this is a normal issue with a vta bov ? It comes with 2 springs I,ll try the stiffer one before I sack it off?

I have a vta on mine, never had any issues

I'd try the stronger spring. Theoretically the BOV should be sealed when sat idling, so the fact it is a VTA should not matter. The car would only stall if the fuelling went wrong, which would imply a leak.

It does mention in the documentation that the stiffer spring should be used depending on the vac at idle I,ll try all of the above cheers all

[Nick Mann]

In John's link above, our cars are at the high vacuum end of the scale, so I'd assume that you would need the stronger spring. In my experience vr4s run a vacuum of around 19inhg.

Yes, I had to change one of my previous bovs springs to a stronger one but that was before I discovered that the cheap Amber Performance ones did all we need impeccably and made a lovely noise.

Sorted I put the stronger spring in and now it works well, I've picked up 0.2 bar as well so the old one must have been leaking, doesn't sound as I had though but oh well
