![]() ![]() Service mode adds some time to the job initially but makes up for it in the ease of engine disassembly and reassembly. Placing the nose in service mode involves removing the front bumper and partially unbolting the vehicle's nose to allow it to tilt away from the engine, creating space. The easiest way to give yourself enough space to work on this engine is to put the nose in service mode. How long will it take to replace the valve cover gasket and PCV on a Volkswagen VR6? Doing the gasket and PCV at the same time will save you a bunch of time and possible future headaches. PCV failures aren't uncommon on VW's VR6 engines, and the process to reach the PCV housing is identical to the one required for a valve cover gasket replacement. For that price, you will receive just a new PCV housing/valve. The kit includes every seal, bushing, and bolt you'll need to replace the valve cover gasket on your VR6 engine. How much will it cost to replace the valve cover gasket and PCV on a Volkswagen VR6? If water does mix with oil, you'll find a murky mixture sitting atop the oil, reminiscent of a chocolate milkshake. Engines create water as they heat up and cool down, and it's the PCV's job to help eliminate the water from the oil. A stuck closed PCV cannot help regulate the engine's pressure and clear the oil of any excess moisture. This vacuum leak will cause an engine to run too lean, leading to misfires and general rough-running. When the valve is stuck open, it creates a vacuum leak in the engine. Oil is a large part of the air that the PCV regulates and is usually a stuck valve's culprit. PCVs break when they become stuck open or closed. The positive crankcase ventilation valve, or PCV, is in charge of keeping the internal engine pressure where it needs to be. Otherwise, there's a chance that the PCV system is causing an issue. ![]() The cause of a leaky gasket can be that the gasket is old and has become brittle. If there is oil, the chances are that the gasket is leaking. Examine the area around the valve cover and check for any oil build-up. Whistling sound while the engine is runningĪ leaky valve cover gasket is easy to diagnose.Oil build-up around the intake manifold.Symptoms of a failing PCV or valve cover gasket on a Volkswagen VR6: No special tools are required, just sockets and screwdrivers. However, this job is achievable in a driveway with hand tools. Getting to the valve cover gasket and PCV housing will be tedious as the vehicle's nose must enter the service position before any engine work can begin. The pressure won't cause any catastrophic damage, but it will push past seals, o-rings, and gaskets. When the vale gets stuck or breaks, pressure builds, eventually finding its way out. The PCV's job is to help any excess pressure leave the engine safely. A faulty PCV valve can cause these types of leaks. The leak may not be bad enough to cause immediate damage, but it will eventually cause an issue. A leaking seal or gasket is a direct cause of a loss of oil. ![]() To run smoothly, an engine requires a certain amount of oil, and that amount of oil needs to be inside the engine at all times. Keeping the oil where it is supposed to be in an engine is an important job. Shown specifically in this video is how to replace the valve cover gasket on a Mk5 VW Golf R32 with the VR6 engine, but this applies to the Golf GTI and VW Jetta as well. This DIY covers how to replace the valve cover gasket and PCV on a Volkswagen VR6 engine. ![]()
