Push the 29mm blank into the OEM plumb back hose and use the factory spring clamp to secure. Use the factory bolts to fit

Replace the engine cover. Start the engine and check for leaks.  
ADJUSTING YOUR BOV  
Each BOV needs to be adjusted to suit the vehicle it is being mounted on. The aim of the adjustment on Vee Port’s, Supersonic’s and  
Dual ports is to make sure that the piston is hard closed at idle and that the piston closes fast enough to minimise backfiring and not  
stall the engine. Plumb back BOV’s are equipped with a spring which are designed to keep the piston open at engine idle and hence the  
cap can be left in the middle position.  
Adjustment to the BOV is made by rotating the cap. To increase the spring force on the piston, rotate the cap clockwise in the direction  
of hard as marked on the top of the cap. To decrease the spring force on the piston, rotate the cap anticlockwise in the direction of soft  
as marked on the top of the cap - CAUTION - Do not rotate the cap beyond the first O-Ring indicator groove.  
Start with the BOV cap at the maximum soft position (The indicator O-Ring should be completely covered by the edge of the cap)  
With the engine at idle the exhaust port should be closed off by the piston the piston should be hard against the seat and not  
floating or moving  
Free rev the engine and back off quickly, the engine should return to normal idle speed if the engine drops below idle or stalls  
increase the spring tension by one turn  
Repeat this process until the engine free revs and returns to normal idle speed  
Test drive the car and ensure that when decelerating or changing gears that the engine has minimal backfiring and no stalling. If  
backfiring is excessive or stalling is noticed then check all connections made during the installation, otherwise increase the spring  
tension  
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.  
Check the seal between the intercooler flange and the BOV. Make sure the supplied gasket is installed and the BOV Flange  
is secured on the intercooler flange with the two factory bolts.  
-
Ensure the spring clamps are secured on silicon hoses and fittings.
