Provent 200 Filter Real v Fake

How to Spot a Fake Provent 200 Filter

When it comes time to replace your Provent 200 filter, be aware of the damage these non-genuine knock-off filters can cause.

As you know, catch cans (or oil separators) are designed to filter fine oil droplets and crankcase fumes from entering the engine inlet areas. When left unfiltered, these fumes gradually coat the intake area with oil. This coating then starts collecting fine carbon particles, which over time create a heavy carbon build-up inside your engine. (New to catch cans? See our diesel catch can comparison for a rundown of the options.)

Fake Provent filters have some obvious faults, and sometimes vehicle owners don’t even know their filter is non-genuine:

• The plastic housing is quite soft and bends easily.
• The filter medium is replaced with a wire mesh.
• The Mann+Hummel branding will be missing.
• There are imperfect tooling marks on the outside of the can.
• The Provent can will gradually warp and the lid will not fit properly.

If your replacement filter is made only with “wire mesh,” it’s definitely a fake — you may as well not have the catch can fitted at all.

What Problems Occur When a Fake Filter Is Fitted?

When servicing Provent 200 filters, we have seen far too many problems that could potentially lead to major engine failures. The two main problems with these knock-off filters are:

Problem 1: No filtration

Fake Provent 200 filters will NOT work properly — you may as well not have one fitted at all. The crankcase oil vapour is not being filtered, and the blow-by fumes are still entering the intake system.

Problem 2: Restricted air flow

If the filter is a material-type filter (mesh, paper, or cloth wrapping), it will be restricting air flow. This can cause:

• Over-pressurising of the sump.
• Massive pressure on engine seals and gaskets.
• Oil leaks, ultimately voiding any vehicle warranty.

At the end of the day, buying your filter from a reputable dealer will ensure your Provent 200 replacement filter is genuine and fit for purpose.
