broken AOS middle tube

[dsulu]

Hello,

Finally have sometime this Thanksgiving weekend to work on my 98 Boxster, (2.5 litre)

Two things I am replacing.

1 AOS and 2 Coolant reservior

Now I ran into some problem while removing AOS, I broke the tube that connects to the middle of the AOS, and it seems that it runs under air intake. Has anyone run into that problem while removing AOS and how hard is it to replace that tube. and what is the part number for it?

Like always, any help is greatly appreciated. :)

The only difficulty with replacing that tube is the limited access, otherwise it's straightforward.

Part number for your '98 is 996.107.147.55, crankcase breather hose.

Maurice,

Thank you for the reply.

Limited access, indeed.

I thought about removing both air intake manifold and it turned out to a huge production. Once again, limited access to that as well.

I am now thinking about using a tube (typical radiator hose) to link the broken parts together and just use a few clamps to keep the tube air tie.

I want to advise everyone that doing AOS is not hard but be VERY careful w/ that middle tube.

I will keep you guys updated! :)

dsulu:

Take a look at the possibility of just removing the two air intake distributors (big black rubber tubes between the manifolds) and the throttle body to gain better access to the crankcase breather hose. Those are only held on with large diameter hose clamps and are relatively easy to remove and replace.

Even if you still go with the "patch" route, it will probably make it easier for you to access the breather hose in that location and will be easier to install a patch there. Also, this will give you a perfect excuse to clean your throttle body, which is also a good idea anytime you have reason to replace the AOS.
