A few days later we’re back in the garage armed with a few drill’s and screw extractors. The 3 bolts have been soaking in a mixture of acetone/ATF. Unfortunately the don’t move a tiny bit. The OAS and water bridge can’t be moved either so drilling isn’t easy with limited movement. After a bit of a struggle we manage to get the gasket from underneath the water bridge. It’s still not moving but we have enough space to squeeze a saw blade into it. With a lot of sweat and small movements the 3 bolts are cut short and the water bridge can be moved. Finally we have space to work.
3 short parts of bolt are still stuck in the valve housing but even now they don’t move.
Drilling them out is the only option but when the drill breaks in the first bolt we quit. We’ve been busy for 7 hours. (The day after at the WEC in Spa Francorchamps the Porsche 919 get’s a new front suspension in 16 minutes!)
