STM EVO X SEALED ENGINE OIL CATCH CAN (FOR METAL VALVE COVER)
STM Evo X "Sealed" Engine Oil Catch Can
Fits these Applications:
2008-2015 Mitsubishi Lancer Evolution X with Metal Valve Cover
(Not for Plastic Valve Cover)
STM Price: $499.00+
The STM "Sealed" Engine Oil Catch Can is specifically designed for the Evo X and features a "sealed" design with no vents or filters, fully containing the crankcase pressure and keeping the excess oil, fuel and condensation from building up in your engine. The new "sealed" design is vented to your intake pipe via an included bung that must be welded on to your existing pipe. We also include a "Check Valve" for routing to the intake manifold to prevent crankcase pressure under boost.
The catch can itself is hand-made, tig-welded in the USA and mounts behind the intercooler on the frame rail for easy drain access and we include a soft, mounting buffer so the can will not scratch your paint. The can is available with a brushed aluminum finish, gloss black or wrinkle black powdercoat.
All fittings and line are safe for use with all oils, E85 and other corrosive race fuels. STM Valve Cover Fittings are included for an easy, direct install to your metal valve cover.
As always, if you have any questions about STM parts or installation or what you need for your specific set-up, please don't hesitate to give us a call!

Lifetime Warranty on STM Parts to the original purchaser against manufacturing defects.
Catch can is mounted on the bottom frame rail, behind the intercooler (pictured below) using the included bolt, lock washer and flat washer.
We suggest a bit of glue or epoxy when installing both the STM fittings in the valve cover. These will only work with the metal valve covers.
-6AN Line and Fittings for Driver Side.
The -6AN 45° fitting attaches to the driver side of the mounted can, leading the hose to the driver side of valve cover which attaches to another -6AN 90° fitting to screw into the small STM valve cover fitting.
The -10AN section of line is to be cut into two separate sections for the passenger side of the can to the valve cover, and for the top of the can to the intake pipe.
-10AN for Passenger Side.
The -10AN 45° fitting attaches to the passenger side of mounted can, leading the hose to the other 45° fitting attaching to the large STM fitting which replaces the PCV valve in the valve cover.
-10AN for Intake Pipe.
We include a -10AN weld bung (stainless or aluminum) which needs to be welded to your intake pipe. The -10AN fittings and line then route to the top of the can. Typically, we place the bung up by the turbo coupler on the bottom side of the pipe, but placement is 100% up to you.
-8AN Rubber Push-On Hose for Intake Manifold.
This will run from the Check Valve and -8AN push-on fitting on the top of the can to the vacuum port on the intake manifold where the factory PCV valve was routed.
If you would like to also purchase the STM Bellmouth Intake Pipe, we can absolutely have the bung welded on for you, then finished to your liking (brushed or black powdercoat). Just give us a call.
