MAINTANCE
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.
Failing the above, submit a technical request to tech@turbosmart.com.au with information of your engine configuration
and photos of installation.
