Vacuum line on intake manifold V70-XC70 1998

Hi All,

I have noticed that the vacuum elbow at the passenger side of the intake manifold is quite soft and collapses from the vacuum - so obliviously I will replace this.

I have picked up a vacuum elbow (part no. 9155862) as replacement. However, this is shaped in 90 deg. whereas it seems that the vacuum line routes from passenger side of intake manif. 180 deg. to join the PCV tube between the engine block and intake. Is it ok to "force" this extra bending on a vacuum tube or is that likely to cause it to collapse?

What does this vacuum connection actually do?

Thank you in advance

Nikolaj

Should work fine. This is the same arrangement as on my 98 T5. Believe it sends some signal to the turbo system regarding state of vacuum and activates the turbo.

Thanks for your quick response!

I'll go ahead with the 90 deg elbow then (probably my biggest worry should be how to get my thumbs in there =;-))

I forgot to mention that I drive a non-turbo -sorry. So this line would not be related to the turbo system.

Nikolaj
