Oil Control System [Mk3 Focus ST/RS]

The mountune Oil Control System for the Mk3 Focus ST and RS includes a baffled oil sump insert and balancer shaft delete.

Validated under extreme circuit conditions, the oil sump insert - developed by mountune’s racing division, features high-quality one-way gates and diverters to maintain oil supply around the oil pump pick-up.

Removing the crankshaft balance shaft assembly from the 2.3L EcoBoost engine frees up rotating mass and helps to improve engine response. This kit also includes a neat balance shaft delete, which can be easily installed in-situ.

The kit is supplied as a pre-assembled insert for ease of installation.


  • CAD-designed baffle plate
  • One-way oil control flaps
  • Supplied with balancer shaft billet blanking plate
  • Facilitates the removal of the balancer shaft

Note: Oil pan/sump not included. Some early pans require one support post to be drilled / tapped for installation. If you'd like us to supply and install using your own sump, please use our HQ installation product option.
