LN Engineering IMS Bearing Retrofit UpgradeFrom £995


What is an IMS Bearing and why upgrade?


One of the weaknesses identified in recent years by Porsche has been the intermediate shaft bearing (IMS bearing), which supports the intermediate shaft on the flywheel end of the engine.


The IMS bearing is a sealed ball bearing which is pressed into the intermediate shaft and is designed to be used in dry conditions, so the area where Porsche designed the bearing to sit must be dry.


After years of use, it would appear that oil and contaminants from the engine seep past the bearing seal, wash out the original lubricant and become trapped inside. The result is that the bearing now operates in a less-than-ideal environment and begins to wear prematurely.


When the bearing wears out, the timing chains on the engine may disengage, causing major damage to the engine (in most cases, it's usually terminal). Also as the bearing deteriorates, swarf debris from the bearing circulates throughout the engine, causing damage to other areas in the engine.


If you are concerned about an IMS failure, we are offering the intermediate bearing retrofit upgrade from £995.00 + vat. The LN Engineering bearing kit is a world leading IMS upgrade that has the reputation of being the best IMS solution available for either the Porsche Boxster 986 or 911 996.



What cars are susceptible to an IMS failure?


All model year 1997-2008 Boxster, Cayman, and 911 models can suffer from IMS failures, with exception of Turbo, GT2, or GT3 models.



How can I check for an IMS bearing problem?


At every oil change, check the filter and magnetic drain plug for any debris (swarf) and/or small pieces of plastic (bearing seal). If sparkly metallic debris is present, you must stop driving your car immediately and install an IMS Retrofit upgrade. Even if there is only a small amount, it is probably a good indication that your bearing is starting to fail.


Other indicators that you may have an IMS issue include oil leaks at the rear of the engine. Oil leaks between the engine and gearbox or usually an indication that there is an RMS leak. However, if the IMS bearing is starting to fail, the IMS flange seal will start to leak oil and this will cause an oil leak between the engine and gearbox (same area as RMS).



How do I know which IMS my engine has?From £995


As long as the engine in your vehicle is original to the car, you can expect to find the following:


If your vehicle has a replacement engine, expect to find the prevailing bearing used by Porsche in those years. If the engine was made for MY06 or later, it will have the late revision, larger IMS bearing which is not serviceable without complete disassembly of the engine.





Is a new oil filter and oil included in the price?


Yes. We will change your oil filter and drain and re-fill your oil with a choice of Mobil 5w40 or 0w40. Also as a matter of course, we will also replace your RMS.


How much will it cost?



All prices are subject to VAT.

Porsche Cayenne V8 Coolant Pipe upgrade from £695From £695


Cayenne Coolant PipesAll Porsche Cayenne V8 models (4.5S and Turbo) manufactured between 2003-2006 came from the factory with plastic coolant tubes located beneath the intake manifold and they are notorious for splitting and leaking due to overheating.


We can remove the original plastic coolant tubes and replace them with the new aluminium pipes which Porsche introduced in 2007 to superseded the older plastic design.


Being made from aluminium, they are far more resistant to heat so as the coolant temperature rises, the pipes do not expand and contract in the same way as the older plastic pipes and therefore are not prone to leaking. This gives you a permanent fix and peace of mind.


Please note: Our price includes the full aluminium coolant pipe upgrade and NOT just the main coolant pipes found under the intake manifold. We only supply geniune Porsche parts.
