I spoke to a mechanic, as this was new to me. He has seen this a few times.

The nut goes on the shaft for the intermediate shaft bearing support. When the nut shears off it is disaster waiting to happen. The bearing for the intermediate shaft falls into the engine and you have engine damage. That is when oil pours out of the hole left by the broken nut.

He has seen just a very few cars where the nut has sheared off and the bearing has not yet moved. Porsche puts a lot of loctite somewhere (I forget where he said) and the bearing may stay in place for while. But when the engine gets hot and/or you rev it up then boom.

He said the bearing support cannot be removed and replaced from the outside of the engine. The engine has to be taken apart. At his dealership the engine is simply replaced.

That is what I was told.

Don't drive the car.

How much does your dealer want to try to fix this?

To replace the shaft and bolt they said it would cost $1200. If the engine needs replacing it would be $6000.

This is a 2003 2.7 that I took in 2003.

The upper green line is where the nut is supposed to be. The lower green line is the broken off nut that fell down. That car was towed in because the engine had already been damaged. That engine was replaced.

This is a good engine. The yellow arrow points to where the nut should be. Right in the middle of the intermediate shaft flange.

Thanks for the information. I will take a look at the engine when I'm back at the dealer.

Hopefully the shaft replacement with solve the problem.
