Why do we join the vacuum lines together with PROcede

CaptOz · 06-26-2007, 04:58 AM

As you know, during the PROcede install the 2 vacuum leads are unplugged and joined together. Why is this?

The reason I ask is because I have tucked (hidden) the join up under the plastic engine surround. This has resulted in a slight kink in the line. Will this matter??

Cheers.

yeah, no kinks!

A slight bend or curve is okay, but a kink is not okay. Try to adjust the hoses accordingly.

I believe the hoses are disconnected from the rear turbo solenoid to act as a bypass?

I'm surprised BMW went with rubber for their vacuum lines instead of the more heat-tolerant, and longer lasting silicone. May turn out to be a worthwhile upgrade for the future.

+1 for silicone hoses. Turbos generate a buttload of underhood heat. Even my tiny T28 keeps the engine compartment pretty toasty...

I am guessing in the future somebody will come out with a silicon hose upgrade kit like for Audi Biturbo S4 and other turbo vehciles. Worthwhile upgrade and reasonably priced for the entire set typically.
