The PCV system and the oil separator play a crucial role in stable engine operation. They maintain crankcase pressure, vent gases, and prevent excess oil from reaching the intake tract. However, in many modern engines, particularly those with turbos, these components often become a source of issues: ruptured membranes, internal cracks, or pressure imbalances can lead to higher oil consumption, erratic engine operation, and dashboard warning lights. In such cases, a PCV Fix Kit allows you to quickly restore system functionality without replacing the entire valve cover.

Typical PCV / Oil Separator Issues
The most common problem is a rupture of the membrane. Under the influence of high temperatures and constant pressure fluctuations, the membrane loses its elasticity, microcracks form, and then it ruptures completely. As a result, crankcase pressure is no longer properly regulated, and the engine begins to operate unstably.
Another typical malfunction is internal cracks in the oil separator housing. They lead to air leakage and vacuum loss, often manifested as a hissing or whistling sound when the engine is running.
Another common issue is pressure imbalance within the system. When the system is unable to vent gases, the crankcase pressure increases, and oil begins to push through seals and gaskets. This causes characteristic oil leaks, sometimes very intense.
Ultimately, a malfunctioning oil separator can cause increased fuel consumption, an unstable idle, detonation, and even misfiring.
What a PCV Fix Kit Includes
A PCV repair kit usually contains the components that most commonly fail and compromise system sealing.
A typical set includes:
- The diaphragm is the main element that regulates pressure and prevents oil from entering the intake. High-quality diaphragms are made of a heat-resistant polymer that withstands constant deformation.
- O-rings – ensure the tightness of the cover and the membrane seat.
- Protective cover or cap – fixes the membrane and closes the repair unit. In reinforced kits, the cover is made of a material resistant to deformation and temperature fluctuations.
All this allows you to quickly restore PCV operation without expensive repairs.
How to Install a PCV Fix Kit
The replacement process is quite simple and does not require deep engine disassembly, but it does require accuracy:
- Preparing the car. The engine must be cooled. Remove the decorative casing and gain access to the valve cover.
- Removing damaged components. Carefully remove the old oil separator cover, remove the damaged membrane, and inspect the seat for cracks or oil residues.
- Cleaning the work area. Remove dirt and remnants of old seals. A clean surface is the key to proper sealing.
- Installing a new diaphragm. Place the diaphragm in the seat, making sure that it is properly aligned and not deformed.
- Installing the O-rings and cover. Install the rings in place and secure the new cover. Check that the latches are securely closed.
- Checking the system. Start the engine and listen to its operation. The absence of whistling, a stable idle speed, and normal throttle response indicates a successful repair.
Advantages of Repairing Instead of Replacing the Entire Unit
Choosing a PCV Fix Kit instead of buying a new valve cover has several important advantages:
- Significant cost savings. A new cover can cost several times as much as a repair kit.
- Speed of work. Repair takes 15-30 minutes, while replacing the entire assembly takes much longer.
- Full restoration of functions. If the cover body is undamaged, the repair kit restores all standard characteristics to the unit.
- Minimal intervention in the design. You do not disassemble unnecessary components or change the factory configuration.
KLIFEX PCV Solutions
The KLIFEX company has established itself as a manufacturer of high-quality membranes and PCV repair kits. Their products are distinguished by heat-resistant materials that do not harden from temperature; exact correspondence to the dimensions of OEM components; durability, confirmed by practice and reviews of technicians; stable operation even in turbo engines, where the loads are much higher.
Choosing KLIFEX, the car owner receives not just a repair kit, but a reliable solution that ensures long-term, reliable operation.
PCV Fix Kit is an effective way to quickly and inexpensively eliminate problems with the oil separator and restore correct crankcase ventilation. Due to its simple installation and affordable cost, such repairs are the best option in most cases. The main thing is to use high-quality components, such as KLIFEX solutions, which ensure system stability, tightness, and a long service life.
