Have you ever heard of or experienced a Porsche IMS bearing failure or wondered how it could impact your vehicle and how you should go about fixing it? Intermediate Shaft (IMS) bearing is a notorious problem in some Porsche models. If not fixed, it can cause serious damage to the engine. It is important to know what IMS Bearing Failure is, how to identify it, avoid it, and where you should take your prized Porsche if you find yourself in such a situation.
What is the IMS Bearing?
The IMS is an essential part of the engine of the Porsches 911, Boxster, and Cayman, produced between 1997 and 2008. It helps position the camshaft for rotation and is pinned to the crankshaft. The IMS bearing facilitates the rotation of the intermediate shaft. However, in certain Porsche models, this bearing wears out earlier than expected, and this leads to failure. If the IMS bearing fails, the camshaft and crankshaft can get out of phase and lead to serious internal damages that may necessitate full engine replacement or rebuilding.
Typical Signs That Indicate IMS Bearing Is Faulty
- Metal Shavings in Engine Oil: One of the first indications of IMS bearing failure is fine metallic chips floating in the oil. When the bearing is worn out, it releases small particles of metal which find their way into the oil.
- Oil Leaks: Another sign is oil seepage around the rear of the engine, where the IMS bearing is situated. If you see oil leaks on the garage floor or realize that your car loses oil often, it may be due to IMS-bearing failure.
- Engine Misfire: When the IMS bearing starts to fail, the engine may stumble or run roughly because some of the moving parts in the engine synchronize poorly.
- Unusual Engine Noises: Abnormal vibrations or thumping noise from the engine, might suggest that the IMS bearing is on its way out. The noise arises from the worn bearing and the overall effects that this wear has on other parts of the surrounding area.
Preventing IMS Bearing Failure
- Regular Oil Changes: Do you know that frequent changing of oil can assist in prolonging the lifespan of the IMS bearing? Clean oil ensures that the bearing is always lubricated and bad particles are not in contact with the bearing. It’s also important to use high-quality engine oil and filters to ensure your engine works as it should.
- Install an IMS Bearing Upgrade: For many Porsche owners, the only way to prevent an IMS-bearing failure is to fit an improved version. There are quality aftermarket parts that can be purchased and are more durable than the bearing initially installed in your old model Porsche.
- Monitor for Warning Signs: Always look for indications that may warn of IMS bearing failure, including metal in the oil or oil leaks. If these complications are not treated early, they can cause more harm to your engine.
- Regular Inspections: Regular checks by a qualified mechanic, preferably someone with experience with Porsche engines, will ensure that IMS bearing problems are noted early enough to prevent complete engine breakdown.
Repairing a Failed IMS Bearing
- Replace the Bearing: If the IMS bearing is worn out, but the other parts of the engine are not damaged, a standard yet stronger IMS bearing can solve this problem.
- Engine Rebuild or Replacement: In the worst case, if the bearing has failed and there is internal engine damage, a total engine overhaul or replacement may be required. This is an expensive fix that also takes a lot of time to be done.
