Oil Catch Tank for Car Modification – Round and Square Models in Four Colours

This oil catch tank is a straightforward component for reducing oil mist recirculation in your engine's intake system. It is particularly useful for modified or high-mileage vehicles where blow-by gases can deposit oil residues on intake valves and intercooler pipes. Made from aluminium alloy, the tank is both lightweight and resistant to corrosion, making it suitable for long-term use under the bonnet. The product is available in two distinct shapes—round or square—and four colour finishes: black, red, silver, and blue.

Features and Construction

The tank is built around a simple but effective design that focuses on reliable separation of oil from crankcase gases. The aluminium alloy body is sealed with press-fit or threaded end caps, and an internal filter aids in trapping oil droplets before they can re-enter the intake tract.

Material and Build

Aluminium alloy is used for the main body and end caps. This material offers a good balance of strength and low weight, which helps reduce stress on mounting brackets and hoses. The surface finish is smooth and painted in the chosen colour, providing a clean look under the bonnet.

Size and Practical Fit

Exact dimensions are not listed, but the tank is intended to fit within the engine bay of most passenger cars. Both the round and square models have a compact footprint. The inlet and outlet ports are sized for standard breather hoses, making connection straightforward with common aftermarket hose kits.

Uses and Placement

This oil catch tank is installed inline between the crankcase breather outlet and the intake pipe. It is used in naturally aspirated and turbocharged engines alike to reduce carbon buildup on intake valves and improve engine longevity in modified cars.

Event or Professional Use

For garage workshops and performance tuners, this tank provides a visible indication of how much oil is being captured, helping diagnose excessive blow-by or poor ring seal. It is a common addition during engine builds and track-preparation work.

Everyday Home Use

DIY car enthusiasts can install this tank at home with basic hand tools. The simple design means it can be plumbed in quickly, and the drain plug allows easy emptying during routine oil changes. The colour options let the owner match the tank to existing engine bay decor.

Benefits and Buying Value

Using an oil catch tank reduces the amount of oil vapour entering the intake system, which helps keep intercoolers, throttle bodies, and intake valves cleaner. This can lead to more consistent engine performance over time and fewer cleaning intervals.

Reuse and Low Maintenance

The tank is reusable—simply drain collected oil and clean the internal filter periodically. The aluminium alloy construction does not rust, so the tank can be used for many years with basic care. There are no disposable filter elements to replace regularly.

Why Choose This Product

This oil catch tank offers a choice of shape (round or square) and colour (black, red, silver, blue) without altering its core function. The inclusion of a pre-installed filter and aluminium alloy build makes it a practical, no-fuss option for engine bay breather upgrades.
