vacuum hose onto the reducer fitting. One 5mm hose clamp is used to secure the supplied 5mm vacuum hose onto the reducer  
fitting, the other is to secure the vacuum hose to the BOV nipple.

ADJUSTING YOUR BOV  
Traditionally every BOV needs to be adjusted to suit the vehicle it is being mounted on. The new SP Dual Port BOV technology  
eliminates the need to adjust the BOV after installation.  
MAINTENANCE  
Turbosmart recommends that the following maintenance procedure is carried out at six monthly intervals or at higher intervals if the  
environment is very dusty or wet. Regular maintenance will ensure that your BOV is operating at its peak performance and will extend  
the working life of the product.  
Remove the cap of the BOV by rotating in an anti-clockwise direction CAUTION, the cap is under spring force, remove with  
care!  
Carefully remove the piston and thoroughly clean the piston and the bore of the BOV  
Inspect the surface of the piston and the bore of the BOV for scoring or excessive wear, silver coloured marks on the bore are  
an indication of excessive wear  
Check the Base O-ring and the Cap O-ring for any damage replace if necessary  
Lubricate the bore and the piston with Uni-Glide™, hydraulic oil or sewing machine oil DO NOT use grease or viscous oils  
Re-assemble the BOV in the reverse order  
TROUBLE SHOOTING  
The following points should be checked if you find that your engine is dipping below normal idle, stalling or if the BOV is functioning  
poorly. Please note, the following checks will cure 99% of problems experienced with a BOV.  
-
Check the vacuum hose for splits, cracks, loose connection, kinking or any obstruction old or fatigued hose may collapse  
under vacuum causing an obstruction.  
-
With the engine running remove the vacuum / boost hose from the nipple in the cap of the BOV, there should a loud hissing  
sound. The engine should idle poorly, double check by covering the end of the hose with your finger otherwise the hose is  
blocked.  
-
-
-
Check to see if the BOV is blocked or contaminated with dirt or debris.  
Ensure that the vacuum / boost source is not shared and that the vacuum source is directly from the inlet manifold.  
Ensure the spring clamps are secured on silicon hoses and fittings.
