In addition, we also wanted to be sure that a slightly smaller hose size would still operate without issue on this application. Given stringent regulations on emissions and that we're tapping into the PCV system, we want to ensure that adding this catch can doesn't result in any unwanted check engine lights. With our prototype complete, the only thing left to do is ensure it works without causing any new problems. This location is a solid foundation for the bracket, which will keep it from running away under heavy vibrations, and provides a direct path for our lines to the PCV connections. So, drawing inspiration from the previous generation kit, our engineer, Anthony, found a cozy spot on the radiator support. Even with the flat-four layout, and low mounted turbo, it's tricky to find a home for our catch can. Like any modern vehicle, the engine bay in the latest WRX is cramped. Pressure in the crankcase is not a good thing, so every engine has a vent to relieve this rebellious gas. Rather, they sneak past the piston rings and into the crankcase, causing pressure. The downside is that not all of the combustion gasses follow the rules and exit the cylinder through the exhaust. This process turns the crankshaft, generating the power to propel you down the highway. Any internal combustion engine operates by using thousands of tiny explosions to drive the piston to the bottom of the cylinder.

If you're scratching your head at the notorious boogyman that is blow-by and how to prevent this monster from attacking your WRX, let's review.

We're already on the case to preserve the WRX's power plant. Like every WRX before this one and fossil fuel-powered engine to hit the streets, blow-by and carbon build-up lurk in the vehicle's intake tract. The trouble is that the VB WRX's main nemesis is itself, or at least the by-product of its operation.

That's not much of a surprise given the impending electrified takeover, but keeping our precious gas burning, manual shifting, turbocharged machines in proper working order is that much more important. Top off the radiator with clean water and replace the cap. Once the flow starts dripping, flush the radiator with water. Open the drainage valve and let the coolant run out. The days of the internal combustion engine are numbered. Put a pan below the drainage valve to catch the old coolant. This corrosion and pH drop is why the ethylene glycol antifreeze type of engine coolant needs to be changed every two years or 24,000 miles.Categories: Subaru WRX Baffled Oil Catch Can, 2022+ So as ethylene glycol antifreeze coolant is heated, cooled, exposed to air, components of the conventional ethylene glycol antifreeze additive package are depleted over time and the pH drops. Why 2 years/24k? From : 'Unfortunately, the buffers in this antifreeze type are chemically transformed or consumed as they function. Guess that means dealers might higher mechanics with no mechanical skill? That last part seems a little strange since it's printed in the manual that Honda service shops use. Per Honda service manual for my bike: inspect every 8k miles, replace at 24k miles, see note 4 which says 'Replace every 2 years, or at indicated odometer interval, whichever comes first. Click to expand.Coolant typically comes with change-interval recommendations based on years or miles.
