The camshaft seal is a small rubber or silicone round shaped piece. It is placed at the extreme end of the camshaft to prevent the spilling out of the engine oil from the camshaft housing. The camshaft itself is used to open and close the engine valves which is very essential for the proper functioning of the engine.

This seal prevents the oil from leaking and helps it to remain where it is most needed to lubricate the camshaft and other parts. If the seal is not properly doing its work, oil can easily leak out and result in low levels of oil and may even damage the engine.

Symptoms That May Indicate You Need to Replace the Camshaft Seal

  • Oil Leaks: A common sign that the camshaft seal has gone bad is oil dripping from the front of the engine. There are times when you will find oil stains around the areas where the car is parked or even observe oil trickling down the engine; this is a clear indication that the seal is damaged. If you often have to add oil to your engine, then there is a possibility that you are dealing with a seal leak in the camshaft.
  • Oil on Engine Components: Whenever the camshaft seal is compromised, oil will drip on the other parts of the engine. You may find the presence of oil on the timing belt or any other part close to the camshaft. Oil seepage can compromise the rubber in the timing belt and other engine parts before its time is due.
  • Burning Oil Smell: If oil comes in contact with hot engine parts, then it gives out a smell of burning oil. Should you smell this when driving or after turning off the car it is wise to look for a leak in the camshaft.

When to Change Your Camshaft Seal

  • During Regular Maintenance: Whenever you take your VW for servicing, for example when you are changing the oil or the timing belt, it is advisable to also have the camshaft seal checked. If your mechanic has observed that the seal is worn out, or there are signs of leakage, then you should replace it. This measure will reduce the chances of your Volkswagen breaking down when you least expect it and it will ensure your car is running optimally.
  • Based on Mileage and Age: Camshaft seals are usually to be replaced after 60,000 to 90,000 miles of the car’s operation. But if your car is of an older model, then you may have to replace the seal at an earlier date. Seals which are usually made of rubber can wear out with time, not necessarily because the car has been in use but due to the fact that rubber does wear out with time. One may need to check from time to time to see whether the seal is still intact or whether it requires replacement.
  • When You Notice Signs of Leakage: Some of the common signs that you may require the services of an expert include; oil leakage, low oil levels, and a burning oil smell. These are the symptoms that suggest that the camshaft seal could be on the way out. If left unchecked, they could progress to a more severe level of engine damage and therefore would cost more to repair.
  • During Major Engine Work: If you have your car engine opened for major work like the timing belt replacement it is advisable to replace the camshaft seal as well. This is economical and effective because all related parts are checked to ensure they are in the correct working condition. To avoid the necessity to disassemble the engine once again, it is better to replace the seal during major overhaul works.
