Ford Sigma Ti-VCT Blanks

Piper does not recommend customers install camshafts in this engine, which are ground to any Piper designed profile, if the engine is to continue to use the standard Ford mapped ECU. To avoid any possible engine damage, Piper strongly advises customers that when installing Piper, or any other non-standard Ford camshafts in this engine, the ECU must be re-mapped accordingly.

Jaguar 6 cylinder Blanks

These camshafts are supplied with either a 3/8-inch UNF grub screw or an 8.5mm ball fitted to the front of the camshaft; please check the grub screw or ball is fitted. These camshafts are also supplied with a 3/8-inch UNF grub screw (not fitted), for instances where triggers are not used. If you are not using triggers, please fit the grub screws to the rear of each of your new Piper camshafts.

Important  When fitting the grub screw, it may be possible to obstruct the oil intake hole in the rear journal once full tightness has been reached. When fitting the grub screw, please use a thread locking compound and fit the grub screw flush to the end of the camshaft. After fitting, please double check no obstruction (fully or partially) to the oil intake hole has been made by the grub screw. Please allow sufficient time for the locking compound to dry before installing the camshafts.
