Intermediate Shaft Failure

[Boxer]

Hi guy's .

I wondered is any of you have any information on this failure.

Can it be prevented?

Or is there any advance warning of failure ?

Thanks in advance for any info.

The intermediate shaft is supported by a bearing on the rear of the engine. This shaft drive things, like the cams via chains. The bearing was a double bearing then Porsche switch to a single bearing. When the bearing fails it damages the engine. I think this change was made in 2001.

Don't know of any way to prevent it since it is a design issue.

You hear a noise like marbles in a can then the engine stops. A nut on the end of the shaft shears off which leave a hole in the back of the engine for oil to pour out. It is too late for you to do anything.

That is the way I understand it.

Thanks for the replie Tool Pants.

Can the bearing be replaced on a service schedule to prevent failure ?

I know its not part of the standard porsche service schedule but would it prevent complete engine failure if it was replaced every 20,000 miles.

Or is it a complete engine strip to extract the bearing ?

Are you aware of many failures ?

Thanks in advance

Search on this board and others. It has been discussed many times and there have even been polls.

The bearing is not available separately, you have to open the engine and change the intermediate shaft completely.
