If you lot're a late model Porsche owner, y'all would have heard the acronym IMS but every time you've jumped on the internet, yous've come away with more questions than answers.

We've spent the time in the workshop speaking with our technicians and distilling the very all-time factual information about IMS bearings, their importance and what exactly does go wrong. Below you'll find the about ordinarily asked questions regarding the IMS bearing along with a simple piece of cake to understand caption of the issues!

Nosotros hope this will help you have a better overall grasp of what exactly the IMS begetting is, what goes incorrect and what is involved to make certain it doesn't happen to you.

What is an IMS bearing?

IMS stands for 'Intermediate Shaft', and the IMS bearing supports the intermediate shaft, on the flywheel end of the motor (See here). The purpose of the intermediate shaft is to bulldoze the camshafts indirectly off the crankshaft. By using an intermediate shaft, the speeds of the chains are reduced, which is meliorate for the chain life. This basic design was used through the entire lifespan of aircooled 6-cylinder Mezger engines used through to 1998. The inclusion of an intermediate shaft which drives the camshafts indirectly off the crankshaft has been a mainstay of the horizontally-opposed apartment 6 engine utilised by Porsche.

The same design has been retained with the water-cooled Turbo, GT2 and GT3 models as their engines are based off the same 964 engine example with the same internals equally the earlier aircooled engines. Although these engines employ an intermediate shaft, with a bearing, they have a fundamentally different blueprint, and are not subject to the same type of failure as the M96 engine.

What Porsche models are decumbent to IMS failure and would benefit from an IMS upgrade.

- All 986 Boxster models.
- 987 Cayman & Boxster models up to engine number 61504715
- All 996 models (not including: GT and Turbo models)
- 997 three.6ltr with M96/05 upwardly to engine number 6950745

What actually goes wrong?

There are so many reasons for bearing failure, and usually each failure is due to a combination of causes, non just a single crusade. Spalling (Ascertain: Spalling) occurs as a upshot of normal fatigue where the bearing has reached the terminate of its normal lifespan merely this is not the about common crusade of IMS failure. Spalling detected in bearings tin generally be attributed to other factors; a common crusade of begetting failure is due to high load and lack of lubrication to the IMS begetting, causing continuous over heating. This volition ultimately weaken the bearing and fracture information technology, leaving backside a jagged depression (or a 'pit'). Once this cycle begins, wear is greatly accelerated and the begetting will fail prematurely.

What is the worst case scenario?

In worst-example scenarios, the cam timing can also be thrown off, causing valve to piston contact. In that instance, the engine will need a full strip downwards and rebuild.

1 thing is for sure; once y'all have experienced an IMS bearing failure, at that place is NO turning back. A complete engine disassembly is required to supercede the intermediate shaft and in most cases, complete rebuild or engine replacement is your ONLY option.

What can be done to fix this mutual problem?

Aside from the proactive arroyo of replacing the IMS bearing prior to such a failure, prevention and early detection are some of the steps that tin can exist taken to try and minimise the take a chance of a costly engine failure.

With model year 1997 through 2005 engines, the bearing is indeed accessible. Any IMS bearing replacement is intended to exist installed as a pro-active measure in preventative and regular maintenance. In one case an engine has suffered a failure, replacement of the intermediate shaft bearing is no longer an option. Installing a replacement IMS bearing in an engine that has already suffered a failure will outcome in a subsequent failure due to collateral damage, including but not limited to debris contaminating the new bearing.

Are there whatever warning signs?

In that location are three warnings signs which tin can indicate a bearing is failing; you lot've institute metallic droppings in the oil filter while conveying out an oil change, or y'all may take found that there'southward an oil leak located at rear of engine, or y'all would accept started to hear knocking and metallic sounds coming from the rear of the motor.

It's of import as soon as y'all spot or hear the problem, call us on (02) 9417 0911for some communication. Do not drive the automobile until it has been inspected by a trained Porsche technician, equally you could cause catastrophic engine damage and failure.

Need more aid?

Nosotros hope we've been able to shine some light and aid you lot take a meliorate understanding of what exactly an IMS bearing is and what can actually go wrong with them.

To hash out the best approach for your machine, give our service squad a phone call on (02) 9417 0911 or electronic mail service@autohaushamilton.com.au
