... and talking about vibrations, AGAIN!

Maybe one of the last indian summer days to drive my Seven was yesterday, but when I started the engine, the needle of my Stack rev counter just broke :-( One more on the list of winter projects.
Cheers.

Rust + vibrations = fracture

Only a frew droplets of coolant on the garage floor and a loose waterpump mounting bolt... but when I wanted to tighten it, it showed that the bolt had broken. Since it is the same bolt used to tense the belt, vibrations may have killed it together with some rust inside the block. I had to use an 'easyout', a conical left drill bit, to get the remainings of the bolt out of the block. An M8 Helicoil repair kit did the rest. Always thrilling to bore into the block. Remount with new gasket and stainless bolt.
Cheers.

Cosmetics

While experimenting with the lambda sensor, I had more or less tinkered an adaptor to the old exhaust. Not beautiful, but functional. With a used exhaust offered from a friend, I took the opportunity to change for a permanent installation. It's an original Westfield can, but I had to weld a lambda boss to it and made a few other mods prior to mounting.
The pic shows the close to finished work in comparison with the old exhaust tube. I have to weld the rear support for the can but haven't started the engine yet. Curious to know how it sounds with the new can.
Funny enough, there is a part numbers match between the can and the manifold I purchased four years ago from another seven driver (16521 to be found both on the can and the manifold).
Cheers.
