Diagnosing Volkswagen Jetta Oil Dipstick Funnel Problems
Your Volkswagen Jetta oil dipstick funnel is a piece of orange tube where you put in the dipstick when measuring oil levels in your engine. This component is made of plastic, which wears out over time. When this happens, you might begin to experience several engine-related problems. You need to troubleshoot the causes behind these issues, so you can think of the most appropriate solution the soonest time possible.
A dipstick is a device that is made of metal. To protect it from rust, you put it inside the plastic funnel. But when the funnel cracks, oil can get into the metal tube. Leaving your dipstick in this condition for days may result in corrosion and engine contamination. To check your dipstick funnel for cracks, simply park the car and open your hood. Do this only when the engine is completely cool. Locate the dipstick in your vehicle. It is usually installed near the exhaust manifold. Gently pull it out for inspection. When you see that the tube has holes and fissures, replace it immediately.
Something is terribly wrong when you see oil flowing out of your dipstick. Overflow is caused by several things. Pressure build up is one of them. Extreme high pressure inside the fuel tank is most likely to happen in a diesel-powered car like a fourth-generation Volkswagen Jetta. Diesel fuel heats up faster causing the pressure to increase rapidly. To verify if you're having this problem, remove the dipstick slowly. If you're hearing a hissing sound, it means that there is a huge pressure build up. Also, check the level of your oil. In some cases, too much oil in the tank causes fuel to blow out of the dipstick funnel.
Contamination of your fuel can lead to something worse-engine contamination. It can affect your car's performance in a very bad way. One of the factors that can initiate contamination is a chipping and flaking oil dipstick funnel. The plastic debris can fall to the bottom of the tank and mix with fuel. During combustion, these plastic pieces can get transferred to the engine and cause blockage or contamination. To troubleshoot this particular issue, you need to inspect the tube thoroughly. Squeeze the plastic funnel to feel if it's squishy. Replace the spongy tube to fix the problem.
