Oil Catch Can

Why Does Your Engine Need an Oil Catch Can?

Direct-Injection Carbon Buildup

On direct injection engines like the 3.5 EcoBoost, 5.0 Coyote, and modern Hemis, fuel sprays directly into the cylinder, so intake valves never get washed by gasoline. Blow-by oil vapor baking onto those valves builds carbon that hurts airflow, causes rough idle, and eventually demands an expensive walnut-blasting cleaning. An oil catch can intercepts that vapor first.

Turbo and Diesel Oil Ingestion

Boosted and diesel engines push significant blow-by through the PCV/CCV system. That oil mist coats the turbo compressor, charge air cooler, and intake, slowly strangling efficiency. Powerstroke owners routinely drain ounces of oil from a catch can that would otherwise have ended up inside the intercooler.

Intake Valve and Throttle Body Sludge

Even on port-injected engines, oil vapor settles as sludge on the throttle plate and intake runners. Over 100,000 miles it adds up to degraded response and dirty airflow metering. A baffled catch tank collects it where you can drain it in seconds.

What Can an Oil Catch Can Solve?

Internal Baffling Condenses Oil Vapor

The best catch can design forces vapor through internal baffles and screens, giving oil mist surfaces to condense on before the air continues downstream. Cheaper empty-can designs let vapor pass straight through; ours captures it.

Drain Valve for Easy Maintenance

Every kit includes a drain valve or removable bottom. At each oil change, open the valve, drain the collected oil into a bottle, and close it. No disassembly, no replacement filters.

Vehicle-Specific Mounting and Hoses

The direct-fit EcoBoost, Coyote, Hemi, and Powerstroke kits come with application-specific brackets, hoses, and fittings, so the can mounts cleanly and the install looks factory. Universal 3/8 and 1/2 inch kits include bracket and hose for custom applications.

Vented Option for Atmosphere Setups

The vented catch can with breather filters crankcase vapor to atmosphere through a top-mounted filter, for off-road builds that want a closed-loop-free setup. It still baffles and catches the oil; the air simply exits filtered.

Frequently Asked Questions

What does an oil catch can do?

An oil catch can sits in the PCV or CCV line between the crankcase and the intake. Blow-by vapor passes through internal baffles that condense oil mist into the can, so clean air continues to the intake and the oil stays out.

Over time this prevents carbon buildup on intake valves, oil sludge in the intercooler and throttle body, and the performance losses that come with them.

Is an oil catch can worth it?

On direct injection engines like the 3.5 EcoBoost, 5.0 Coyote, and Hemi, yes: it is the cheapest insurance against carbon-caked intake valves that cost hundreds to clean.

On diesels like the 6.0 and 6.7 Powerstroke it prevents oil ingestion into the turbo and intercooler. The first time you drain an ounce of black oil from the can, the value is obvious.

Are oil catch cans bad for your engine?

A properly installed, properly maintained catch can is not bad for your engine. The problems come from cheap empty cans with no baffling, or from owners who never drain them until the can fills and liquid oil is drawn through.

Our baffled designs with drain valves eliminate both failure modes. Check the can at every oil change and you will never have an issue.

Which catch can fits my 3.5 EcoBoost F150?

Our 3.5 EcoBoost catch can kit covers 2011-2023 F150s and mounts on the driver side PCV circuit, which is where boosted engines push the most blow-by.

The kit includes the vehicle-specific bracket, hoses, and fittings, so it is a clean bolt-in with no universal fitting guesswork.

Do catch cans work on diesels?

Yes, with the right can. Diesel blow-by volume is higher than gas engine blow-by, so we offer the 1/2 inch high-flow universal can plus direct-fit ccv catch cans for the 6.0 and 6.7 Powerstroke.

On diesels the catch can keeps oil out of the turbo compressor and charge air cooler, preserving boost efficiency and reducing the oily residue that collects in intercoolers.

How often do I need to empty a catch can?

Check it at every oil change. Most engines collect a few ounces per interval; tuned engines and diesels can collect more.

Draining takes seconds with the built-in drain valve. If you notice the can filling unusually fast, that can be an early sign of excessive blow-by from worn rings or a failing turbo seal, making the can a diagnostic tool too.

What is the difference between a catch can and an oil separator?

Functionally they describe the same product category: a reservoir that separates oil from crankcase vapor. Some brands market them as oil separators or air oil separators, others as catch cans.

The meaningful differences are internal: baffled and filtered designs like ours capture far more oil than empty can designs, regardless of the name on the box.

Should I run a vented or closed catch can?

A closed system routes filtered vapor back into the intake, keeping emissions equipment happy and sealing the system, the right choice for street vehicles.

A vented catch can with breather releases filtered vapor to atmosphere, common on off-road and race builds. Check local emissions rules before choosing the vented route on a street-driven vehicle.

Can I install a universal catch can on any engine?

Yes. The universal 3/8 inch kit suits most gas engines, and the 1/2 inch high-flow version handles diesel blow-by volume. You route the PCV/CCV line through the can, mount the bracket, and secure the hoses with the supplied clamps.

Take time with hose routing to avoid kinks and heat sources, and confirm the can sits lower than the vapor source so oil drains back into the can, not the line.

What is your return policy and warranty on catch cans?

EGR Performance offers 45-day worry-free returns and a one-year warranty on every oil catch can and separator kit we sell.
