Colour Choice Oil Catch Tank for Car Modifications: Round or Square Can Design

This oil catch tank provides a functional upgrade for modified cars, focusing on the practical task of separating oil mist and unburned gases from the engine's crankcase ventilation airflow. By installing this unit in-line with your vehicle's PCV or breather system, you can intercept these contaminants before they reach the intake manifold or turbocharger. This process helps reduce carbon build-up on intake valves and within intercoolers, which is a common concern in performance and modified engines. The product is offered with a straightforward choice, allowing you to select a colour and a can shape that best suits your engine bay's aesthetics and available space.

Features and Construction

The core function of this catch tank is to provide a chamber for oil vapour to condense and collect, separating it from the crankcase gases. It is a self-contained unit designed for integration into your car's existing ventilation plumbing.

Material and Build

The specific metal or polymer used in the can's construction is not detailed, but it is engineered as a sealed container capable of holding automotive fluids. It will feature inlet and outlet ports for hose connections, and a removable section or drain plug for emptying the accumulated fluid. The design prioritises its role within a pressurised engine system.

Size and Practical Fit

While exact measurements for the round and square models are not provided, the availability of two distinct shapes offers flexibility for installation. A round can might fit more easily into tight, curved spaces, while a square model could offer a different mounting profile against flat surfaces. The choice allows you to assess your engine bay layout during the planning stage of your modification project.

Uses and Placement

This product is intended for use in petrol or diesel engine bays where managing crankcase emissions is desired. It is a common modification for turbocharged engines, high-performance naturally aspirated engines, and track-focused vehicles.

Event or Professional Use

For competitive motorsport or rigorous track day use, a catch tank is often a required safety modification to prevent oil spillage onto hot surfaces. It also serves a performance role by ensuring that oil vapour does not contaminate the intake charge, which can lower the effective octane rating of the fuel mixture and potentially lead to detonation under high load.

Everyday Home Use

For the road-going modified car, the primary benefit is maintenance reduction. By catching oil vapour, it helps keep the intake system, throttle body, and any intercooler components cleaner for longer periods. This can contribute to more stable idle quality and sustained performance between service intervals, without the need for frequent intake cleaning procedures.

Benefits and Buying Value

The value of this catch tank lies in its straightforward proposition: a single, complete component that addresses a known issue in modified engines, offered with basic customisation options.

Reuse and Low Maintenance

The tank itself is a durable item designed for long-term use. Its maintenance involves the simple, periodic task of draining the collected fluid, which can often be incorporated into a regular oil change routine. There are no consumable filters or complex parts that require frequent replacement, making its ongoing upkeep minimal.

Why Choose This Product

This unit provides a direct solution for enthusiasts looking to add a catch tank without needing to source separate cans, fittings, and brackets. The inclusion of four colour options and two shapes means it can be selected to complement the visual theme of an engine bay, moving beyond a purely utilitarian black box. It is a ready-to-install component that simplifies one aspect of car modification.
