STM Transmission-Mount Engine Oil Catch Can with 3-Port Valve Cover & Engine Block Breather - Evo 8/9

STM Tuned Inc.


Vehicle Fitment:
2003-2006 Mitsubishi Lancer Evolution VIII IX

The STM Transmission-Mount Engine Oil Catch Can is designed to mount right to your 5-speed or 6-speed transmission in the 2003-2006 Evolution VIII-IX. The mounting tabs allow you to re-use the existing transmission bolts and places the catch can right under the intake, out of the way with easy accessibility to the drain plug.

The STM 3-Port Valve Cover & Engine Block Breather design includes everything to properly route the can to the valve cover as well as a vent directly to the crankcase. We include all high quality swivel fittings and braided nylon hose, both STM Valve Cover Fittings for a clean and direct install, and the Engine Block Fitting which is placed on the front side of the engine, behind the turbo.

Please verify that you have enough room behind your turbo to install the Engine Block Fitting and 120° swivel fitting before you purchase and attempt to install.

We include 15 feet of nylon braided line for you to route the install any way you want. The soft nylon also will not scratch paint or other finishes. We suggest a touch of glue or epoxy when installing the STM Valve Cover Fittings. The larger fitting goes in the back side of the valve cover, deleting the PCV valve. The can bolts directly to your transmission using existing bolts, be sure to select the correct transmission when ordering.

As always, if you have any questions regarding your set-up, please feel free to give us a call.

The fitting itself is a very tight fit, but we would definitely recommend a touch of glue or epoxy to help hold it in place in the valve cover upon install. We recommend the ThreeBond Gasket Maker.
