While the DISI-MZR engine found on the Mazdaspeed 3, 6, & CX-7 is a fun and potent powerplant, it does have some common issues that must be addressed with age and if you want to produce more power. One common issue is the OEM VVT Actuator which controls the Variable Valve Timing of the intake camshaft. Actuator failure commonly sounds like a rattle and/or chain slap from the passenger side of the engine. This is due to the actuator losing its ability to hold oil pressure and keep tension on the timing chain.
Luckily, Mazda revised the OEM VVT Actuator with a stronger and more durable design that eliminates this failure from happening in the future. On average, we see engines needing this part replaced once they are in the 70k to 100k mile range.
We have put together a complete VVT Actuator Replacement Kit so you don’t have to worry about which parts are needed and which are not! With that we have also developed a Timing Plate and Crank Pin Kit which IS REQUIRED to complete the installation of the new VVT Actuator Kit which is included in this package deal
Required for installation of the VVT Actuator Kit, the CorkSport Timing Plate is CNC machined from stainless steel and includes two Crank TDC Pins in case you lose or damage one. This are made from 6061-T6 Aluminum and finished with a red color so you don’t leave it in the engine. Arguably the best feature of the timing kit is the included bottle opener that is built into the cam gauge. This was an important feature for us to include because we know that after this job, you’ll more than likely want something cold to drink like we do.
Each VVT kit comes with all new OEM components featuring the Mazda revised intake camshaft VVT actuator.
It will take you 6 hours to install the VVT replacement Kit.
